Trunk Bay is the most famous beach on St. John and possibly the most famous beach in all the Caribbean. It has perfect powdery white sand and an under water snorkel trail with plaques describing the various items that snorklers can see on the bottom. No visit to St. John is complete without a visit to Trunk Bay. Run by the National Park, there is a fee to access the beach from land, $4 for visitors over 16 years of age. There are facilities at the beach and visitors can rent snorkel gear as needed. There is also a new service that is called SNUBA, that allows visitors to simulate diving without dive equipment.

Trunk Bay has the most modern and convenient facilities and receives the most visitors of any beach on St. John. It is a breathtakingly beautiful beach, with perfect soft white powdery sand extending into the sea. The beach is bordered coconut palms, seagrapes and beach mahos and the lush tropical vegetation extends into the flat valley floor where the Trunk Bay facilities are located. The turquoise and blue water is crystal-clear and the panoramic view from the beach picture-perfect. More on Trunk Bay from the St. John Beach Guide
