Our Favorite Big Island Snorkeling Spots
Kealakekua Bay

Arguably the most famous snorkeling destination on the island, Kealakekua Bay offers pristine waters and plentiful marine life. It’s also home to the iconic Captain Cook Monument. Snorkel here to explore vibrant coral gardens, spot spinner dolphins, and marvel at clear water with unparalleled visibility.
Pro Tip: This bay is best accessed by kayak or a guided tour, as the surrounding trails can be challenging.
Honaunau Bay (Two Step)

Known locally as Two Step, this spot earns its nickname from the two rock “steps” that make entry into the water easy. Honaunau Bay is celebrated for its calm waters and abundance of colorful fish and sea turtles.
Pro Tip: Arrive early before the crowds and enjoy the serene waters in the morning light.
Kahaluu Beach Park

This family-friendly spot is excellent for beginner snorkelers. With shallow waters and a high likelihood of spotting sea turtles, it’s a great place to introduce kids and first-timers to the joys of snorkeling.
Pro Tip: Stay on the right side of the beach for the clearest waters and best underwater sights.
Green Sand Beach (Papakolea)

While famous for its unique green sand, Papakolea also offers adventurous snorkeling opportunities in certain areas near the coastline. This spot is more remote, so it’s ideal for those seeking an off-the-beaten-path experience.

Mahukona Beach Park

Less crowded but equally enchanting, Mahukona Beach Park is perfect for snorkelers who cherish tranquility. The underwater scenery features colorful coral reefs and a variety of fish species.
