Congratulations on your marriage! Now for the fun part: planning an unforgettable honeymoon. If you're a couple who craves both adventure and relaxation, with a landscape that changes dramatically every hour you drive, look no further than Hawaiʻi Island. Its sheer size and diversity—from fiery volcanoes to lush rainforests and pristine beaches—make it a destination unlike any other for starting your new life together.

Why Choose the Big Island for Your Honeymoon?

Unlike any other Hawaiian island, the Big Island is a world of its own. It’s home to 8 of the world's 13 climate zones, meaning you can go from sunbathing on a white-sand beach to bundling up for stargazing at nearly 14,000 feet in a single day. It’s the island for couples who don't want to choose between adventure and luxury. You can hike across a still-steaming caldera in the morning and sip cocktails by an infinity pool in the afternoon.

Here you’ll find active volcanoes, sand in shades of white, black, and even green, and a palpable sense of history and culture. It’s less about the high-energy nightlife and more about profound, shared experiences—watching the cosmos unfold from a mountaintop, swimming alongside gentle manta rays, or simply holding hands on a secluded beach.

Where to Stay: Romantic Resorts & Secluded Retreats

The island has two distinct sides: the dry, sunny Kona side (west) and the lush, tropical Hilo side (east). Where you stay will shape your experience.

  • The Kohala Coast: Located on the northwest side, this is the island's epicenter of luxury. You'll find sprawling, world-class resorts with stunning pools, championship golf courses, and decadent spas. This area is known for its reliable sunshine and postcard-perfect beaches. It’s the quintessential choice for couples who want to be pampered.

  • Kailua-Kona: The main town on the west side is a more bustling hub with a wider range of hotels, condos, and vacation rentals. It’s a convenient base for activities like snorkeling tours, boat trips, and exploring the famous Kona coffee belt. The atmosphere is more energetic and less secluded than the Kohala Coast.

  • Volcano Village & the East Side: For a unique and rustic experience, consider spending a few nights in a cozy cabin or boutique inn near Hawaiʻi Volcanoes National Park. Waking up in a misty ʻōhiʻa rainforest is incredibly romantic and provides easy access to the park for early morning hikes. Nearby Hilo is the island's lush, rainy capital, offering a more local, less-touristy feel.

For most honeymooners on a trip of 7 days or more, we recommend a split stay: start with luxury and sun on the Kohala Coast, then move to a more intimate setting in Volcano or Hilo for a few nights of adventure.

Unforgettable Activities for Two

The Big Island's adventures are perfect for making memories together. Here are a few essential experiences.

Stargazing on Mauna Kea

The summit of Mauna Kea is one of the most sacred places in Hawaiian culture and one of the premier sites for astronomy on Earth. While access to the true summit is restricted after sunset for commercial tours, the Maunakea Visitor Information Station (VIS) at 9,200 feet offers a phenomenal vantage point. The clarity of the Milky Way is breathtaking. Remember to acclimatize to the altitude and dress warmly in layers—temperatures drop significantly.

Exploring Hawaiʻi Volcanoes National Park

This UNESCO World Heritage Site is a dynamic landscape of creation and destruction. It's home to Kīlauea, one of the world's most active volcanoes. Drive the scenic Chain of Craters Road down to the coast, walk through the Thurston Lava Tube (Nāhuku), and hike the Kīlauea Iki trail across a solidified lava lake. Before you visit, always check the official National Park Service (NPS) website for current conditions and closures. For real-time eruption updates, the USGS Hawaiian Volcano Observatory is the definitive source.

Snorkeling and Marine Life Encounters

The calm, clear waters of the Kona coast are legendary. Kealakekua Bay, a protected marine life conservation district, is a snorkeler's paradise. For a truly magical, only-on-the-Big-Island experience, book a night snorkel or dive with manta rays. Tour boats use lights to attract plankton, which in turn draws these gentle giants. Watching them glide and somersault through the water just inches away is an experience you will never forget.

Chasing Waterfalls on the Hāmākua Coast

The windward Hāmākua Coast, north of Hilo, is a stunning stretch of lush valleys, sea cliffs, and dramatic waterfalls. A scenic drive will take you to ʻAkaka Falls State Park, where a pleasant loop trail leads to views of the towering ʻAkaka Falls (442 feet) and the smaller Kahūnā Falls.

Relaxing on World-Class Beaches

The Big Island is famous for its rainbow of sand colors, a direct result of its volcanic geology.

  • White Sand: Hāpuna Beach State Recreation Area is a long, wide stretch of perfect sand, consistently ranked among the world's best beaches. It's ideal for swimming and sunbathing.
  • Black Sand: Punaluʻu Black Sand Beach is the most famous, where you can often see honu (Hawaiian green sea turtles) basking on the jet-black shore. Please admire them from a respectful distance of at least 10 feet, as recommended by state and federal guidelines.
  • Green Sand: Papakōlea Green Sand Beach, one of only a few in the world, gets its unique color from olivine crystals. Reaching it requires a strenuous 5-mile round-trip hike or a paid ride from locals with 4WD vehicles, but the reward is a truly unique landscape.

Romantic Dining Ideas

Many of your most romantic moments will be over a shared meal. The Kohala Coast resorts offer exceptional oceanfront dining, perfect for a sunset dinner. For a true taste of the island, seek out farm-to-table restaurants like Merriman's in Waimea, which pioneered the Hawaiʻi Regional Cuisine movement. Don't be afraid to explore the casual eateries in Kona and Hilo for authentic local grinds like poke and plate lunches.

Sample Honeymoon Itineraries

The 7-Day Romance & Relaxation Itinerary

  • Base: A resort on the Kohala Coast.
  • Focus: Unwind and connect. Spend your days enjoying the resort pool, getting a couples massage, and relaxing at Hāpuna Beach. Plan a sunset sail, a romantic dinner, and a half-day trip to snorkel at Kealakekua Bay.

The 10-Day Ultimate Adventure Itinerary

  • Base: 6 nights on the Kona/Kohala Coast, 4 nights in Volcano or Hilo.
  • Focus: See it all. Use your time on the west side for sun and sea: snorkel, take a surf lesson, and do the manta ray night swim. Then, transfer to the east side to explore Hawaiʻi Volcanoes National Park for two days, drive the Hāmākua Coast to see waterfalls, and enjoy the lush scenery.

Practical Tips for Your Honeymoon

  • Car Rental: A rental car is essential. The island is large, and public transport is not geared for visitors. Book your car far in advance, especially if you want a 4WD, which is useful for reaching some remote areas.
  • Packing: Pack for multiple climates. You'll need swimsuits, reef-safe sunscreen, and sun hats, but also a warm jacket, long pants, and closed-toe shoes for visiting Mauna Kea and the cool uplands of Volcano.
  • Book in Advance: For a honeymoon, it's wise to book accommodations, rental cars, and key activities (like a manta ray snorkel or luau) several months ahead of time to ensure availability and better pricing.
  • Luxury Touches: For those seeking the pinnacle of luxury, a curated experience from a service like High End Hawaii can elevate your honeymoon with private tours and exclusive accommodations.

Frequently asked questions

How many days do you need for a Big Island honeymoon?
We recommend at least 7 days to enjoy one side of the island without feeling rushed. For a more complete experience that includes both the sunny Kona coast and the volcanic east side, 10 to 14 days is ideal. This allows for a split stay and minimizes long driving days.
What is the best time of year to visit for a honeymoon?
Hawaiʻi's weather is beautiful year-round. For the best combination of great weather, fewer crowds, and potentially lower prices, consider the 'shoulder seasons' of April-May and September-October. These periods are fantastic for a more relaxed honeymoon atmosphere.
Should we stay in one place or move around the island?
For trips under a week, staying in one location on the Kona or Kohala coast is simplest. For longer trips of 10 days or more, a split stay is highly recommended. Spending a portion of your trip in Kona/Kohala and another portion in Volcano or Hilo lets you experience the island's incredible diversity.
Do we need to rent a car for our honeymoon?
Yes, a rental car is absolutely essential on the Big Island. The distances between sights are vast, and public transportation is not a practical option for visitors. Book your car well in advance, as they can sell out during peak seasons.
What's the most romantic side of the Big Island?
The sunny Kohala Coast is traditionally seen as the most romantic, with its luxury resorts, spas, and spectacular sunsets. However, the moody, lush rainforests and intimate inns around Volcano and the Hāmākua Coast offer a different, deeply peaceful and secluded kind of romance.
Can you see flowing lava on the Big Island?
Lava activity on Kīlauea changes constantly. Recent eruptions have typically been contained within Halemaʻumaʻu crater at the summit, creating a spectacular glow visible at night from overlooks in Hawaiʻi Volcanoes National Park. Surface flows are rare. Always check the official USGS Hawaiian Volcano Observatory website for the latest conditions.
