Frequently Asked Questions
What can I do in an hour?
The Reef Bay hike takes almost six hours, starting from the Visitor Center at 9:30 a.m. Mondays and Thursdays (schedule changes during the winter months). Reservations are required and there is a transportation fee. Hikers should bring adequate water, lunch and a swimsuit. See the Weekly Programs brochure for more details.
Where is the best snorkeling?
The calm warm waters around St. John provide great opportunities for snorkeling. Some of the best areas for snorkeling can be accessed from the shoreline. Stop by the VisitorCenter for a park brochure and snorkeling guide.
Did You Know?
The mangrove forests found along the coastline in some bays serve as nursery habitats for juvenile fish. These beautiful trees with aerial roots provide filtration of the runoff and reduce the amount of sediment reaching the ocean. The Red Mangrove is one of several species found in the Park.
