Key Largo or Key West Snorkeling?
Key Largo: the technical choice
John Pennekamp Coral Reef State Park sits in shallower water and is protected from open ocean swell. Visibility is often 20–40 feet. The reef is pristine and the water is so clear that nervous swimmers report feeling safer. The downside is that tours are pricier and boats take longer to reach the reef (about 45 minutes from shore). If you want the most technically sound reef dive in the Keys, it is Pennekamp.
Key West: the social choice
We sell the Key West reef tour ($35 per person). It departs from a busier port, the reef is closer (about 15 minutes by catamaran), and the boats get crowded during peak season. Visibility can be spotty (10–20 feet in rough conditions). That said, the price is unbeatable, the boat includes drinks after snorkeling, and you can add a sunset sail. The tour is 4.3 stars from 493 reviews — solid, with honest notes about crowds.
The honest trade-off
If you are nervous, new to snorkeling, or want the best technical reef, Key Largo is the better choice. If you want the cheapest entry to the real reef, do not mind a crowd, and value the post-snorkel drinks and sunset option, Key West is the better value. Both are North America’s only living coral reefs. Neither is wrong; they are just different.
If you go to Key West, book a morning tour. The afternoon boat gets crowded and the water gets choppy. Morning is significantly calmer.
