Magens Bay Beach Day Guide: Swim, Snorkel & Arboretum on St. Thomas
A nearly perfect crescent of white sand and calm turquoise water, Magen's Bay on St. Thomas is an ideal half-day escape for swimmers and snorkelers. Read on for what to expect, how to plan your visit, and practical tips to make the most of this protected Caribbean bay.
The Experience
Before You Go
Arrive early
Beat the cruise crowds—early morning gives glassy water for snorkeling and far fewer beach chairs to navigate.
Use reef-safe sunscreen
Protect coral and marine life by choosing mineral-based sunscreen and applying before entering the water.
Bring small bills
Pay vendors and any modest park fees with cash; some services accept cards but smaller operators may not.
Stay hydrated and shaded
Bring a refillable bottle and a light shade; the sand and sun can drain energy quickly on a four-hour visit.
