Arrive at Daniel K. Inouye International Airport and take a short taxi or shuttle to your Waikiki hotel; drop your bags, change into swimwear, and head straight to Waikiki Beach for a shoreline walk where the famed Waikiki Reef breaks frame your first Pacific surf views. The golden stretch is busiest at sunset, and walking hand-in-hand along the Kuhio Beach section as the light softens is an effortless, romantic way to reconnect after travel while your feet sink into warm sand; bring reef-safe sunscreen and a light wind layer since January mornings and evenings are breezy. After the walk, join a sunset sailing or catamaran cruise that departs from Waikiki Harbor and offers a front-row seat to Diamond Head silhouetted against a sun-dipped sky; choose a small-boat operator for a quieter experience — January is a calm time for Waikiki sails and you may spot the first migrating humpback spouts offshore. Finish the evening with a moonlit stroll through Kapiolani Park, where banyans and palms frame the skyline and you can plan the next day’s early hike up Diamond Head with an early-start tip: arrive before 7:30 AM to beat crowds and secure parking.

Start early with a hike up Diamond Head State Monument (Lēʻahi) to greet expansive views across Honolulu and Waikiki; the trail ascends through tunneling switchbacks, historic military bunkers, and a narrow summit staircase, culminating in a panoramic lookout where you can see the Waikiki coastline, offshore reefs, and the curve of the island. The climb is steep but short — plan 1.5–2 hours round-trip — and January’s cooler mornings make the ascent especially pleasant; carry water, a small headlamp for the darker tunnel sections if you like, and sunscreen for the exposed summit. Once down, reward yourselves by walking the surfside path toward Kapiolani Park and take an optional short snorkel at the calmer edge of Waikiki Reef to test your gear and the warm Pacific water; a gentle confidence-building snorkel here is a perfect prelude to deeper ocean adventures later in the trip.

Late afternoon, cross over to Ala Moana Beach Park’s Magic Island for an easy paddleboard or tandem kayak rental as a couple, gliding in protected lagoon waters beneath palms and between local paddlers; January trade winds are usually moderate, so choose the lagoon for a relaxed outing and a chance for playful close-quarters time on the water without full open-ocean exposure. Paddle out together toward the breakwall to watch surfers on the outside and listen for distant whale spouts during January’s peak humpback season, then return in time to dry off and watch a Waikiki sunset from the gentle gradient of Ala Moana’s lawn. Top the evening with a calm walk through Ala Moana Center’s open-air sections if you need supplies or a casual souvenir; plan the next day’s transport to North Shore or rental pickup if you’ll be exploring the island broadly.

Rise early for a guided sunrise ascent of the Diamond Head alternative if you prefer contrast — the Koko Head Crater Trail is a steep, stair-climb challenge that rewards you with expansive coastal panoramas and a shared sense of achievement; the 1,048 railroad-tie steps are hard but short, and tackling them together at first light makes for a quiet, bonding adventure. January mornings on Oahu are cooler and the air is crisp at the ridge, so layer up for the high-exertion climb and enjoy the dramatic feeling of being above the island as the sun warms the sea below. After descending, refuel at a local café in Hawaii Kai or back toward Waikiki and head to Hanauma Bay Nature Preserve for mid-morning snorkeling—note that Hanauma Bay is federally managed, closed on Tuesdays (verify the exact weekday before planning), and requires a short orientation video on-site, which is a great way to learn about local reef stewardship and marine life protection. The protected bay shelters vibrant reef gardens full of colorful fish and green sea turtles (honu) when conditions are calm; arrive early in January to avoid later crowds and to maximize calm water windows for snorkeling with a guided operator if you want extra local insight.

In the afternoon, take a scenic drive across to Makapuʻu Beach Lookout and, if conditions permit, hike the Makapuʻu Lighthouse Trail to watch for whale spouts in January’s active humpback migration; the paved ridge trail is moderate and offers dramatic cliffs, basalt outcrops, and close views of offshore islets. For a more intimate ocean outing, continue to Sea Life Park or book a guided kayak out to the offshore Rabbit Island (Manana) from Waimānalo for a sheltered paddle and wildlife sightings — these windward waters in January can be breezy, so choose a guided operator who times launches for the calmest windows. Wind down the day back in Waikiki with an evening stretch on the beach and plan tomorrow’s drive across the island to the North Shore for big-wave viewing and valley hikes.

Drive across to the North Shore and begin at the historic surf town of Haleʻiwa for a stroll through artful surf shops and locally run outfitters; take a private surf lesson at a calmer break suitable for beginners if you want a hands-on ocean challenge together, or instead choose a tandem SUP lesson for a cooperative balance test on gentler water. January transforms the North Shore into a big-wave theater farther up the coast, so keep lesson locations carefully selected with your instructor who monitors conditions; the learning vibe and lots of shared laughter make for an unbeatable couple’s memory even if the waves are modest where you practice. After your lesson, wander Haleʻiwa’s friendly main street and pick up a packaged picnic to enjoy at Haleʻiwa Beach Park while watching pros and local surfers pick lines at the famous nearby peaks.

In the afternoon, visit Waimea Valley for a cultural walk through botanical gardens and a hike down to Waimea Falls where you can swim in an enclosed pool beneath a broad cascade; the valley’s botanical and cultural center offers demonstrations of ancient Hawaiian crafts and chant (oli), bringing context to the landscape, and January rains usually keep the falls flowing beautifully. The valley walk is gentle and lush, with interpretive signs and a safe, supervised swimming area at the base of the falls — a romantic place to wade together and cool off after a morning of waves and sun. Finish the day at Ehukai Beach Park (Banzai Pipeline) or Sunset Beach to safely watch massive winter swells and champion surfers tackle the lineup; from the lookout points you’ll witness the raw power of the Pacific and perhaps catch a sponsored competition or free-surf session if events are scheduled in January.

Before driving back toward Waikiki for the night (or staying on the North Shore for a quieter evening), stop at the Polynesian Cultural Center’s gift area if you’d like more context on island cultures — though the main center’s evening performances run seasonally, the adjacent village atmosphere and craft demonstrations make for a calm cultural coda to a high-energy day. In January the North Shore’s large surf can create spectacular light and spray at sunset; time your return drive to coincide with golden-hour views across the windward side if you’re heading back to Honolulu, or choose a small beachfront guesthouse in Haleʻiwa for an intimate night under the stars.

Catch a morning inter-island flight from Honolulu (HNL) to Kahului Airport (OGG) — flights are typically 30–40 minutes — and pick up a rental car to head west into the lush West Maui Mountains; the short flight is convenient and the views of scattered islands and deep-blue channels set a dreamy tone. Drive to Iao Valley State Monument and take the short, shaded walks to the Iao Needle lookout and surrounding lush trail network; the valley is steeped in Hawaiian history and the cool, fern-filled air in January makes exploration comfortable and vivid, with waterfalls and streams fuller in the winter months. Spend a couple of hours exploring the interpretive trails and learning about the valley’s role in Hawaiian history, then continue toward the historic town of Wailuku for a coffee stop before heading to the coastal towns of Kaanapali or Lahaina for a late afternoon shoreline stroll and sunset vantage points.

In the late afternoon, choose a guided whale-watching trip departing from Lahaina Harbor — January is prime humpback whale season, and experienced naturalist-led charters from Maui reliably locate feeding and breaching whales when sea conditions are favorable. Opt for a smaller, more intimate boat or an eco-friendly operator that prioritizes respectful distances and education; being with an onboard naturalist in January will deepen your understanding as you observe tail slaps, breaches, and flukes in the cooler offshore waters. Cap the night with a relaxed walk along Lahaina Front Street or Kaanapali Beach to celebrate the day’s mountain-to-sea contrast and plan tomorrow’s Road to Hana departure early in the morning for the full adventure.

Leave very early from Paʻia (or your West Maui base) and set out on the Road to Hana, planning frequent stops for waterfalls, short hikes, and coastal lookouts; January’s winter rains mean waterfalls are typically flowing strongly and roadside pools and cascades look their most dramatic, so bring waterproof layers and expect lush scenery. Key stops include Twin Falls for a short morning walk and a quick dip when safe, the Garden of Eden arboretum for a forested stroll, and the dramatic roadside views at Keʻanae and the Hana town harbor area where tidal pools and lava rock formations create unforgettable seascapes. Move deliberately and prioritize a few deep experiences rather than trying to check every stop, because the road is about the journey—the curves, small roadside stands selling banana bread, and intimate rainforest clearings make for a romantic, on-the-road mood.

Press on past Hana to Haleakalā National Park’s Kipahulu District and take the Pipiwai Trail through towering bamboo and past ancient gulches to Waimoku Falls, a 400-foot cascade that feels like a secret revealed at the end of a cinematic forest hike; the trail is around 2 miles each way and January conditions mean muddy sections and spectacular water flow, so wear grippy shoes and plan 2–3 hours for the hike so you can savor the forest cathedral atmosphere. After the hike, pause at Waiʻānapanapa State Park on the return for the striking black sand beach and coastal sea arches—this is a highlight for photos and a quiet beach walk if conditions permit. Return to your accommodation in the late evening, tired but exhilarated; January’s earlier sunsets mean you’ll enjoy a slower, cozier night to reflect on the day’s dramatic landscapes.

Take a morning inter-island flight from Kahului to Kona (KOA), roughly 30–50 minutes in the air, pick up a rental car, and head south along the Kona coast to Pu`uhonua o Hōnaunau National Historical Park (Place of Refuge) where shaded stone enclosures, royal grounds, and coastal palms reveal a fully tangible chapter of Hawaiian history; wander the shorelines and learn about kapu systems and refuge traditions as you soak in the ancient dignity of the site. January’s trade winds are present but Kona’s west side is often sheltered, making coastal walks and shoreline exploration comfortable and evocative for couples interested in cultural backstory before setting off for sea-based adventures. Spend about 60–90 minutes here before continuing along the Kona coast toward Kealakekua Bay for your afternoon guided sea trip.

Book a guided kayak or small-boat snorkel excursion to Kealakekua Bay (the Captain Cook Monument coastal preserve) departing from Keauhou or nearby; the bay’s underwater visibility can be excellent in January and it’s one of Hawaii’s top snorkeling destinations for healthy reef, colorful fish, and sometimes spinner dolphins seen offshore. Many operators provide interpretive snorkeling guides who point out reef ecology and best viewing spots; as a couple, choose a small-group or private kayak to make the experience intimate and adventurous, paddling together to the bay and then snorkeling in the protected cove. In the evening, round the day with the iconic Kona Manta Ray Night Snorkel departing from Keauhou Bay — guided night dives or snorkels allow you to float above the ocean floor while plankton attract cruising manta rays that perform graceful barrel rolls close to your light; January is a reliable time for manta activity, and this gently thrilling encounter is one of the world’s most romantic and surreal marine experiences when done with a reputable operator who emphasizes safety and respect for wildlife.

Drive from Kona or take a short inter-island flight into Hilo (if you prefer to reposition by air) and head toward Hawaiʻi Volcanoes National Park, allowing roughly 1.5–2.5 hours driving time from Kona depending on stops; the route across the island is scenic and marks a clear landscape transition from sun-drenched coastlines to lush rainforests and volcanic desert. Start at the Kīlauea Visitor Center to get up-to-the-minute trail and safety information, then explore the Crater Rim Drive viewpoints where you can walk the short trails around the Kīlauea caldera, visit the Sulphur Banks boardwalk to see colorful mineral deposits and steam vents, and wander through the Thurston Lava Tube for that surreal tunnel-in-the-forest experience. January’s winter water patterns often keep the park green and flowing in parts, but dress warmly for higher elevations and reserve at least a half day to see the main sights comfortably; if there are current viewing advisories or after-dark glow opportunities from Halemaʻumaʻu, park staff will brief you so you can plan a safe evening visit or ranger program.

In the afternoon, drive Chain of Craters Road toward the coast for a long, scenic descent through varied lava flows with dramatic coastal views where lava once reached the sea; step out at select pullouts for short hikes across hardened pahoehoe fields and to view contrasting textures of newer ʻaʻā flows. If you’d like a more extended trek, choose one of the park’s longer backcountry trails for a truly immersive volcano-formed landscape walk, but always check conditions and carry water, rain gear, and warm layers—January brings cooler nights and possible light rain in the park. Return to a Volcano-area lodge for a quiet evening among cloud-forested ridges and plan the next morning’s short drives toward the airport for your flight to Kauai.

Take a morning flight from Hilo or Kona to Lihue (LIH) — inter-island flights are typically under an hour — pick up your rental car, and head west to Waimea Canyon (the drive from Lihue to Waimea Canyon lookout is about 75–90 minutes). Stop at the main Waimea Canyon Lookout for the classic panoramic view known as the “Grand Canyon of the Pacific,” where layered red-and-green cliffs descend into deep valleys and waterfalls visible in January’s wetter season. From the overlook, choose a couple-friendly hike such as the Canyon Trail to Waipoʻo Falls for an intimate descent through native shrubs to a waterfall viewpoint; allow 2–3 hours for hiking round-trip and take care on muddy sections in winter months—pack sturdy shoes, rain layers, and thermals for the cooler ridge temperatures.

In the afternoon, continue up into Kokee State Park for higher-elevation trails and additional lookout points that frame the Napali cliffs from the top; Kokee offers several shorter loops and birdwatching opportunities along ridge trails that feel wild and secluded even in January. Finish the day at a viewpoint to catch golden light across the canyon — winter light can be soft and dramatic — and return to a west-side lodge (near Waimea or Hanapepe) for a quiet evening, or position yourselves for an early Na Pali flight or boat experience the next morning.

Choose an early-morning helicopter tour from Lihue that traces the Na Pali Coast and Waimea Canyon for a breathtaking bird’s-eye perspective of sea cliffs, cascading winter waterfalls, and narrow valleys inaccessible by road; operators such as Blue Hawaiian Helicopters and Jack Harter Helicopters run flights from Lihue and offer narrated routes that highlight geological and cultural history. January can present dramatic cloud and water features over the cliffs—conditions that enhance the sense of scale from the air—so book a front-row seat and layer up for cooler altitudes. An aerial trip is a supremely romantic and adventure-rich way to see the inaccessible wildness of Kauai in a short timeframe, offering great photographic opportunities and a sweeping finale to your multi-island odyssey.

If weather cancels aerial options or you prefer sea-level drama, take a Na Pali boat cruise that departs from Port Allen (Eleele) or from the North Shore when conditions permit; experienced captains navigate winter seas to reveal sea caves, sea cliffs, and remote beaches, and some tours include snorkeling stops in sheltered coves. Boat cruises in January are operated by seasoned captains who watch for windows of safer passage—select a smaller, more agile vessel for a more intimate and adventurous experience and pack windproof layers, motion-sickness remedies if needed, and waterproof camera protection. Finish your final afternoon with a relaxed drive to Hanalei Bay (or nearby beaches) for a sunset stroll on the sand and a quiet moment reflecting on the week’s hikes, ocean encounters, and volcanic vistas before heading home the next day.

If you have additional flight time before departure from Lihue, stroll the Hanalei Town pier and crescent beach for a last taste of Kauai’s north-shore charm; January’s waters can be cooler and the surf more active, but the long beach and views across to the mountains make a languid final stop for a couple to savor the island’s softer mood and plan a return. Allow at least 45–60 minutes drive time back to Lihue Airport from Hanalei to accommodate traffic and car return, and check your inter-island flight schedule carefully—January’s weather can shift quickly, so leave buffer time for travel to the airport.
