1. Kealakekua Bay – Captain Cook Monument
Kealakekua Bay is the definitive destination for anyone seeking the best captain cook snorkeling hawaii experience. Located on the Big Island’s protected Kona coast, this Marine Life Conservation District is a pristine underwater sanctuary. The bay is historically significant as the site where British explorer Captain James Cook first landed on the island and was later killed in 1779.
Today, the bay's main draw is its exceptionally clear water, with visibility often exceeding 100 feet. This clarity reveals a thriving, vibrant coral reef teeming with diverse marine life. Snorkelers are treated to schools of colorful tropical fish like yellow tang and parrotfish, and it's common to spot Hawaiian spinner dolphins playing in the bay's deeper waters.
Why Snorkel Here
The primary snorkeling area is directly in front of the white obelisk of the Captain Cook Monument on the shore. This spot offers a dramatic drop-off, allowing you to float over shallow coral gardens before peering into the deep blue abyss. The calm, sheltered conditions make it an ideal spot for both new and experienced snorkelers. For those considering various options, learn more about why Kealakekua Bay is consistently ranked among the best snorkeling spots on the Big Island.

3. Sea Quest Hawaii – Rafting Adventures to Captain Cook
For those craving a more adventurous journey, Sea Quest Hawaii offers an exhilarating alternative for a captain cook snorkeling hawaii experience. Instead of traditional catamarans, they utilize rigid-hull inflatable boats (RHIBs) for a faster, more intimate tour.

The trip itself becomes a thrilling part of the adventure, as the rafts zip along the stunning coastline. Sea Quest has earned numerous TripAdvisor Travelers' Choice awards and recognition from the Hawaii Ecotourism Association for their engaging and responsible tours. Their focus is on combining the incredible snorkeling at Kealakekua Bay with coastal exploration and prime opportunities for dolphin watching.
Why Snorkel Here

The maneuverability of the rafts means you get a comprehensive coastal tour in addition to your time in the water at the Captain Cook Monument. This type of tour is ideal for adventure-seekers who want more than just a boat ride to a snorkel spot; it's a dynamic marine safari that provides a unique perspective of the Kona coast's dramatic volcanic landscape.
Practical Tips for Visiting
- Be Prepared: Wear quick-dry clothing as you will likely get sprayed. Bring a waterproof bag to protect electronics and other valuables.
- Gear Up: It's wise to accept the wetsuit tops they offer, even in summer, as the water can feel cool after the fast ride. Secure hats and sunglasses with straps.
- Comfort: For the smoothest ride on the raft, try to sit in the middle. The ride can be bumpy, so this tour may not be suitable for those with back problems or very young children.

Several local companies offer both guided tours and rentals, launching from Napoopoo Beach for the approximately 1.5-mile paddle to the monument.
The journey itself typically takes 30-45 minutes each way, offering breathtaking views and the potential for wildlife sightings before you even get in the water.

- Gear Up: Apply waterproof, reef-safe sunscreen before you leave shore and bring a small dry bag for water, snacks, and valuables. Water shoes are highly recommended for the rocky entry.
- Book Ahead: Especially during peak tourist season, it's wise to reserve your kayak rentals or guided tour at least 2-3 days in advance.
- Safety First: Check the weather and ocean conditions before departing. For safety, it’s best to follow the coastline rather than cutting straight across the bay’s open water.
5. Captain Cook Monument Hiking Trail
For adventurous and budget-conscious travelers, the Captain Cook Monument Trail offers a challenging but rewarding land-based route to the world-class snorkeling at Kealakekua Bay. This difficult 2-mile (one-way) trail descends a steep 1,300 feet from Highway 11 directly to the monument.

Despite the challenge, completing the hike provides a unique sense of accomplishment and grants free access to the pristine marine sanctuary. Hikers are rewarded with stunning coastal views along the way and a more secluded experience at the bay, often arriving before or after the main tour boat crowds. This trail is a favorite among experienced local hikers and is frequently featured in Hawaii adventure guides.
