St. John might have the lion’s share of the Virgin Islands’ natural attractions, but the extraordinary concentration of flora and fauna in St. Thomas’ Mangrove Lagoon makes it a top eco-tourism destination.
Small kayak groups thread through the lagoon’s tiny red mangrove islands, with guides pointing out the huge diversity of birds they attract, including herons, egrets and ducks.
The route takes you to deserted Cas Cay island, where hermit crabs dart about among mangrove roots. On your gently-paced travels you’ll see young fish darting around this natural breeding ground. Low-impact snorkeling will get you even closer, and you’ll spot rays, eels and jelly fish as well as a host of colorful tropical fish.
Mangrove Lagoon is in the southeast of St. Thomas, less than 15 minutes’ drive away from the capital, Charlotte Amalie.
