Kona, Hawaii: One of the Pacific's Best Adventure Destinations
If you're planning a trip and looking for fun things to do in Kona Hawaii, here's a quick overview of the top experiences:
- Manta ray night snorkel - Float above feeding manta rays after dark at Keauhou Bay
- Captain Cook snorkel tour - Explore the crystal-clear marine sanctuary at Kealakekua Bay
- Whale watching - Spot humpback whales along the coast (December to April)
- Beach days - Swim, snorkel, and watch sea turtles at Kahaluu Beach Park or Magic Sands
- Coffee farm tours - Taste world-famous Kona coffee straight from the source
- Pu'uhonua o Hōnaunau - Walk through one of Hawaii's most sacred historical sites
- Historic Kailua Village - Explore Hulihee Palace and Mokuaikaua Church on foot
- Local food scene - Try fresh poke, shave ice, loco moco, and malasadas at local spots
- Volcanic landscapes - Hike lava fields and explore lava tubes near Hawaii Volcanoes National Park
- Family attractions - Visit a working seahorse farm or catch an immersive indoor flight experience
Close your eyes and picture Hawaii. Rugged lava rock meeting crystal-clear water. Sea turtles basking in the sun. Manta rays gliding silently through the dark ocean at night.
That's Kona.
Located on the dry, sunny west coast of the Big Island, Kailua-Kona averages only about 20 rainy days per year. That means almost every day is a good day to get outside — and into the water.
Kona has a different energy from Maui or Oahu. It's less polished, more rugged, and feels genuinely lived-in. The town is small enough to walk, but the surrounding coastline, volcanic highlands, and coffee country stretch for miles in every direction.
Whether you have a single afternoon or a full week, Kona rewards curious travelers who want real experiences — not just resort pools. One traveler described seeing over two dozen manta rays on a single night snorkel, with the rays gliding close enough to nearly touch. That kind of moment is exactly what Kona does best.

Water Adventures: Fun Things to Do in Kona Hawaii on the Ocean
When you visit the Kona Coast, the ocean isn't just a scenic backdrop—it's the main event. Thanks to the towering peaks of Mauna Loa and Mauna Kea blocking the trade winds, the waters off Kailua-Kona are exceptionally calm, clear, and teeming with marine life.
From the historic waters of Kealakekua Bay to the sheltered sanctuary of Keauhou Bay, there are endless ways to get wet. To help you plan your aquatic itinerary, here is a quick comparison of the two most iconic water-based activities we offer on the Kona Coast:
| Feature | Morning Captain Cook Snorkel | Night Manta Ray Swim |
|---|---|---|
| Best For | Coral reefs, tropical fish, and historical sightseeing | Surreal, up-close encounters with gentle giants |
| Visibility | Exceptional daylight clarity (often exceeding 100 feet) | High-contrast viewing illuminated by powerful lights |
| Wildlife | Spinner dolphins, green sea turtles, hundreds of fish species | Reef manta rays (Mobula alfredi) feeding on plankton |
| Vibe | Sunny, scenic, relaxed, and highly educational | Adventurous, dramatic, and bucket-list worthy |
Snorkeling the Pristine Waters of Captain Cook
The Captain Cook Monument at Kealakekua Bay is widely considered the premier snorkeling destination in all of Hawaii. Because this bay is a highly protected Marine Life Conservation District, boat traffic is strictly regulated, keeping the coral reefs remarkably healthy and vibrant. On any given day, water visibility here can exceed 100 feet, revealing a bustling underwater metropolis of yellow tangs, parrotfish, and green sea turtles.
You might also spot a pod of wild spinner dolphins resting in the calm waters of the bay. Federal guidelines require staying at least 50 yards away from dolphins to protect them.
While you can reach the monument via a grueling, hot downhill hike or by obtaining a kayak permit, taking a dedicated boat tour is by far the most comfortable and reef-friendly option. Our Captain Cook Snorkel Tour starts at $79.99 per person for a 3-hour excursion, taking you directly to the best spots on a fast, small-group vessel led by certified naturalists.
Experiencing the Magic of a Manta Ray Night Snorkel
If you ask anyone who has visited the Big Island to name their single favorite memory, chances are they will say snorkeling with manta rays at night. This is not just one of the most fun things to do in Kona Hawaii; it is widely ranked as one of the top marine encounters in the entire world.
At Manta Ray Village, located just outside Keauhou Bay, high-powered lights are shone into the water after dark. These lights attract microscopic plankton, which in turn attract majestic reef manta rays (Mobula alfredi). Unlike stingrays, manta rays have no teeth, barbs, or stingers—they are completely harmless filter feeders.
As you hold onto our floating light board, these gentle giants—some boasting wingspans up to 16 feet—perform mesmerizing, acrobatic somersaults just inches beneath you. Our Manta Ray Night Snorkel Kona starts at $99.99 per person for a 2-hour tour, providing a safe, ethical, and incredibly intimate way to experience this nighttime phenomenon.
Seasonal Whale Watching Along the Kona Coast
If you are lucky enough to visit Kona during the winter months, you are in for a spectacular treat. Every year between December and April, over 8,000 humpback whales migrate from their icy feeding grounds in Alaska to the warm, shallow waters of Hawaii to breed, give birth, and nurse their calves.
Watching a 45-ton marine mammal breach completely out of the water is a heart-pounding experience you will never forget. On our Whale Watching Kailua Kona tours, starting at $99.99 per person for a 2-hour trip, we use our fast, maneuverable boats to get you close to the action while strictly adhering to ethical wildlife guidelines. Our expert naturalist guides will teach you all about whale behavior, and we even use hydrophones so you can listen to their hauntingly beautiful whale songs live.
If you want to customize your ocean adventure or host a larger group, we also offer Private Charters. Our customizable Kona Private Boat Tour on the "Holo Holo" starts at $1,050 for up to 34 guests, making it perfect for family reunions or special celebrations.
Sun-Drenched Beaches and Outdoor Land Activities
Once you've dried off from your ocean excursions, Kona’s diverse terrain offers plenty of dry-land adventures. From powdery white-sand beaches to rugged volcanic trails, the west side of the Big Island is an outdoor playground.
Relaxing on Kona's Best Beaches
Kona’s beaches are as diverse as they are beautiful. For a classic family beach day, head to Kamakahonu Beach (often called King Kam Beach), located right in downtown Kailua-Kona. Protected by a stone breakwater, its shallow, glassy waters are perfect for toddlers and paddleboarders.
If you're looking for excellent shore snorkeling, Kahaluu Beach Park is a must-visit. This sheltered cove is famous for its abundance of large green sea turtles (honu). Just remember to keep a respectful distance of at least 10 feet from these sacred creatures, and always wear legally required reef-safe, mineral-based sunscreen to protect the delicate coral.
For a bit of local magic, check out Magic Sands Beach Park (Laaloa). It earned its name because its soft white sands can completely disappear overnight during big winter swells, leaving only black lava rock until the gentle summer currents wash the sand back ashore. If you're willing to drive a bit north, Kua Bay (Maniniowali Beach) offers breathtaking turquoise waters and fine white sand that rival any beach in the South Pacific. You can find more detailed beach recommendations in the Kailua-Kona Travel Guide: Beaches, Activities & Local Tips (2026) .
Hiking and Exploring Volcanic Landscapes
Kona's dramatic topography is a direct result of volcanic activity, and there is no better way to appreciate this than by exploring on foot. For a unique hiking experience, make the 20-minute drive upslope to the Kona Cloud Forest Sanctuary. Located high on the slopes of Hualalai, this cool, misty sanctuary features towering tree ferns, native birds, and ancient volcanic trails that feel worlds away from the sunny coast.
If you want to see active volcanic features, a day trip to Hawaii Volcanoes National Park (about a 2.5-hour drive from Kona) is highly recommended. There, you can hike across vast craters, peer into active steam vents, and walk through the famous Thurston Lava Tube (Nāhuku), an easy 0.4-mile trail through a massive cave carved by flowing lava. To help you plan your land-based excursions, check out our guide to the Top 10 Things to Do in Kona Hawaii.
Rich Cultural Heritage and Historical Sites
Beyond its natural beauty, Kona holds a deeply sacred place in Hawaiian history. It was the birthplace of King Kamehameha I, who unified the Hawaiian Islands, and served as the capital of the Hawaiian Kingdom.
Stepping Back in Time at Puʻuhonua o Hōnaunau
Located about 20 miles south of Kailua-Kona, Puʻuhonua o Hōnaunau National Historical Park is one of the most culturally significant sites in the state. Historically, this "City of Refuge" was a safe haven for lawbreakers, defeated warriors, and civilians during times of war. If a person could reach this sacred ground, they were absolved of their transgressions by a priest and spared from death.
Today, you can take a peaceful self-guided walking tour through the royal grounds, admire the formidable Great Wall (built around 1550 out of dry-stacked lava rock), and view the menacing wooden carvings (ki'i) that guard the sacred temple house. It is a place of immense peace and historical gravity. To discover more sacred spots nearby, explore our guide to Attractions in Kailua Kona Hawaii.
Visiting Historic Kailua Village
You don’t have to drive far to experience Hawaiian history; much of it is preserved right in downtown Kailua-Kona (Historic Kailua Village). Take a self-guided walking tour along Alii Drive to visit Hulihee Palace, which served as a breezy summer residence for Hawaiian royalty in the 19th century.
Directly across the street stands Mokuaikaua Church, the very first Christian church established in the state of Hawaii (founded in 1820). Its historic structure, constructed using local lava rock and a mortar made from crushed coral, is a fascinating architectural marvel. For a complete list of historical landmarks and walking routes, check out this guide on What to do in Kailua Kona .
Kona's Famous Coffee Culture and Local Culinary Delights
Kona's unique microclimate—featuring sunny mornings, rainy afternoons, and rich volcanic soil—creates the absolute perfect conditions for growing some of the finest coffee beans on Earth.
Touring an Authentic Kona Coffee Farm
To truly appreciate Kona's agricultural heritage, you must visit a working coffee farm in the volcanic foothills of the Hualalai and Mauna Loa mountains. Many local farms, such as Hala Tree or Rooster Farms, offer fascinating tours where you can walk among the coffee trees, learn about the meticulous harvesting process (every single cherry is hand-picked!), and enjoy a fresh coffee tasting. You might even get to try unique products like tea brewed from discarded coffee cherry shells. For tips on how to integrate a coffee tour into your vacation, check out this detailed The Best Kona Itinerary: 3 Days in Kona, Hawaii .
Savoring Local Flavors and Fresh Poke
All that exploring is bound to work up an appetite, and Kona's food scene does not disappoint. If there is one dish you absolutely must try, it is fresh Hawaiian poke. Made with locally caught yellowfin tuna (ahi), soy sauce, sesame oil, and sea salt, it is the ultimate taste of the Pacific. Local spots like Da Poke Shack or Honaunau Poke Shop serve up some of the freshest bowls you will find anywhere.
For breakfast, treat yourself to hot, sugary malasadas (Portuguese-style yeast donuts) from a local bakery. And to cool off in the afternoon, nothing beats a towering Hawaiian shave ice drenched in tropical syrups like lilikoi (passion fruit), mango, and coconut. For more culinary recommendations, check out our guide to Things to Do in Kailua Kona.
Family-Friendly Attractions and Unique Indoor Experiences
If you are traveling with children, Kona is an incredibly welcoming destination with plenty of activities designed to keep young minds engaged and active.
Immersive Flying Rides and Indoor Fun
If you need a break from the midday sun or encounter a rare rainy afternoon, head to the lobby of King Kamehameha’s Kona Beach Hotel. There, you will find Flight of Aloha | Flying Ride in Kailua Kona, Hawaii , an immersive indoor flying ride.
This Native Hawaiian-owned attraction uses state-of-the-art 8K aerial resolution, motion seats, wind, mist, and signature scents to simulate soaring over Hawaii's most beautiful landscapes. It beautifully blends high-tech thrill with traditional cultural storytelling (moʻolelo), making it a fantastic experience for visitors of all ages, from toddlers to grandparents.
Educational Wildlife Encounters for Kids
For a unique, hands-on marine science experience, take the family to the Ocean Rider Seahorse Farm located near the Kona Airport. As a working marine conservation and research facility, it offers guided educational tours where children can learn about the plight of wild seahorses and the importance of ocean conservation. The highlight of the tour is undoubtedly the chance to hold a live baby seahorse in your hands as it wraps its tiny tail around your finger.

Frequently Asked Questions about Fun Things to Do in Kona Hawaii
What are the absolute must-do fun things to do in kona hawaii?
If you only have a few days in Kona, you should prioritize three signature experiences:
- Snorkeling with Manta Rays at Night: Easily the most unique and surreal marine encounter in Hawaii.
- Snorkeling Kealakekua Bay: Home to the Captain Cook Monument, offering world-class water clarity and reef health.
- Touring a Kona Coffee Farm: A wonderful way to experience the island’s rich agricultural history and volcanic highlands.
Is Kona or Hilo better for a family vacation?
Kona and Hilo offer completely different vacations, and many families choose to split their stay between the two sides.
Kona, on the west coast, is sunny and dry, making it the best choice for beautiful white-sand beaches, resort amenities, boat tours, and ocean activities. Hilo, on the east coast, is lush and rainy, making it ideal for viewing massive waterfalls, exploring rainforests, and visiting Hawaii Volcanoes National Park. If your family loves swimming, snorkeling, and sunny weather, Kona is the clear winner.
How many days do you need to experience the best fun things to do in kona hawaii?
While you can see the main highlights in a busy 3-day itinerary, we recommend spending 4 to 5 days in the Kona area. This allows you to experience a morning snorkel cruise, a night manta ray swim, a coffee farm tour, and historical sites without feeling rushed. Because public transit is very limited and rideshares can get expensive, renting a car is highly recommended to explore the coast at your own pace.
Conclusion
Kona is a place where natural wonder, rich history, and thrilling adventure come together to create lifelong memories. Whether you are floating in the dark ocean as giant manta rays dance beneath you, sipping fresh coffee in the volcanic highlands, or walking the sacred grounds of ancient Hawaiian kings, the spirit of aloha is alive in every corner of this beautiful coast.
At Dolphin Discoveries, we are proud to offer small-group, naturalist-led ocean adventures out of historic Keauhou Bay. We believe in ethical wildlife encounters, eco-friendly travel, and sharing the true magic of the Kona Coast with our guests.
