4 Cave Snorkeling and Swimming in the USA Worth the Trip

1.Kona Snorkel Tour: Captain Cook Reef Snorkel, Dolphin & Sea Caves

★★★★★★★★★★4.5 · 1,411 reviews · 2 hours 45 minutes (approx.) · from $71Our pick

Ride a fast Zodiac RIB from Kailua-Kona to Kealakekua Bay with guides such as David, Chip, Sage, or Danielle. Snorkel near the Captain Cook Monument, then cruise past lava tubes and sea caves. Pineapple, water, and basic snorkel gear are included. Dolphins and whales are possible, never promised.

“Danielle and David took us to where Finding Nemo and Moana got their inspiration and we can see why. The water was so calm and pristine, our best camera couldn't capture the beauty of it. You just have to be there truly. They were rather knowledgeable and told lots of stories and history tidbits about the region. My parents came to visit from China and don't swim very well. They were beyond patient and kind making us feel comfortable. This was the highlight of our 10 day Hawaiian trip honestly. PS: If David's mother is reading this, David is a terrific captain and really great at his job!!! 🌴”
