Snorkelers are often greeted by vast coral gardens teeming with schools of yellow tang, parrotfish, and butterflyfish. It’s also a frequent resting spot for pods of spinner dolphins, which can often be seen leaping from the water.

Its sheltered waters are home to beautiful coral gardens, a variety of colorful reef fish, and are a well-known hangout for Hawaiian green sea turtles (honu), making it an excellent spot for both new and seasoned snorkelers.

7. Night Snorkeling with Manta Rays: A Magical Underwater Ballet

For a truly unforgettable Kona experience, snorkeling with giant manta rays at night is an otherworldly adventure that simply cannot be missed.

This activity has become an iconic part of Kona's identity, offering one of the most unique and thrilling encounters with marine life available anywhere in the world.

The primary reason this experience ranks among the best snorkeling in Kona is the sheer spectacle and proximity to these massive, harmless creatures. Participants hold onto a floating light board while the manta rays perform their feeding dance below.
