About Snorkeling in St. John USVI
Snorkeling in St. John USVI is an independent guide to the best ways to get into the water on the island — from guided catamaran tours out of Westin St. John to the free shore-entry snorkel spots you can reach with your own mask and fins. We compare every option in one place so you can choose the right experience in minutes. Ready to book? Browse the St. John snorkel tours on the homepage.
Why we built this site
St. John has some of the best snorkeling in the entire Caribbean — protected by the Virgin Islands National Park, which covers about 60% of the island and most of its offshore waters. But finding accurate, side-by-side information about guided tours, free spots, and what each one actually includes is harder than it should be. Booking platforms shuffle results by commission and sponsored placement, and most guide sites are thin content with no real comparison.
We fix that. Every tour on this site is researched in detail: departure point, inclusions, boat type, which reef sites are visited, what the crew is actually like in the water, and what the food situation is. We also cover the free shore-snorkel spots — Maho Bay, Salt Pond Bay, Cinnamon Bay, Trunk Bay's underwater trail — because the best morning of snorkeling on St. John might cost you nothing.
How we choose the tours
We do not list every tour on the market. We feature tours that meet a consistent set of standards:
- Run by licensed, insured operators with USCG-certified crew
- Strong, consistent reviews across verified booking platforms
- Clear inclusions — gear, food, drinks, and transport listed honestly
- Fair cancellation policy — all tours featured here offer free cancellation 24 hours in advance
How we make money
This site is free to use. When you book through a link on this page, we may earn a small commission from the booking platform — at no extra cost to you. The price you see on the operator's page is the same price you pay whether you arrive from this site or any other.
Commissions never determine the order or ranking of a tour on this site. Our comparisons reflect verified reviews, real inclusions, and honest value.
