Just 22 miles from Los Angeles, Catalina Island has clear, clean water that’s great for snorkeling. Giant kelp forests wave just beneath the surface, and you can go snorkeling from the beach, or rent a kayak to paddle to a quiet cove. Guided snorkel tours can get you even farther afield, but a wetsuit is a must in the chilly off-shore water. If you're sifting through search results to find the top snorkeling vacations in the USA, stop here. We—or rather, all of our TripAdvisor reviewers—have already done the hard work for you. Our algorithm analyzed every traveler review on our site, identifying which USA destinations are among the world's top places to snorkel.* Go beneath the surface on both coasts, and you can swim with manatees, spot shipwrecks, or go eyeball-to-eyeball with a giant sea turtle.
