The island is surrounded by warm, clear waters with a variety of vibrant coral reefs, schools of tropical fish, and an array of marine creatures such as sea turtles, dolphins, and even the occasional manta ray. The variety of snorkeling spots across Oahu means that whether you’re looking for shallow, family-friendly waters or more adventurous and less-crowded locations, there’s something here for you.
Oahu Snorkeling Locations
There are several Oahu snorkeling locations that are considered the best places to snorkel in Oahu. Let’s take a look at some of our favorite places:
1. Hanauma Bay
The Crown Jewel of Snorkeling Oahu
Hanauma Bay is arguably the most famous snorkeling spot in Oahu, and for good reason. This crescent-shaped bay, formed within a volcanic cone, is a protected marine life conservation area that boasts a staggering variety of marine life. With over 400 species of fish, including the brightly colored parrotfish, triggerfish, and the Hawaiian state fish, humuhumunukunukuapua’a (reef triggerfish), snorkeling here is like swimming in an aquarium.
Why Hanauma Bay is the Best Place to Snorkel in Oahu
• Calm, Shallow Waters: The bay’s natural shape protects it from strong currents, making it an ideal spot for beginners and families with children.
• Educational Experience: Before entering the water, visitors are required to watch a short video about marine conservation, which ensures everyone is aware of how to protect the delicate ecosystem.

• Protect the Environment: As a marine life conservation area, it’s important to respect the rules—avoid touching the coral, and don’t feed the fish. Protect yourself from the sun while minimizing your impact on the delicate coral reef ecosystem by applying reef-safe sunscreen.
• Closed Days: The bay is closed on Mondays and Tuesdays to allow the ecosystem to recover from the influx of visitors. Plan your trip accordingly.

Adventure Awaits on the North Shore
Don’t let the name scare you—Shark’s Cove is one of the best snorkeling spots on Oahu’s North Shore, particularly for those looking for a more rugged and adventurous experience. Despite the ominous name, Shark’s Cove is not known for actual sharks, but rather for its fascinating rock formations and the incredible variety of marine life that inhabit its waters.
