These Are the 11 Best Caribbean Beaches You Can Visit Without Needing a Passport, From St Thomas to Puerto Rico

Magens Bay, St Thomas

The mile-long curve of Magens Bay is enclosed by two green peninsulas, creating calm water that often feels more like a lake than the open Caribbean.

You can rent a paddleboard, swim across the protected bay, order lunch near the center of the beach, or walk toward the quieter ends beneath the sea grapes. The broad stretch of sand gives families, couples, residents, and cruise visitors room to find their own part of the bay.

Magens is also one of the best places to experience the local rhythm of St Thomas. Island families come here for weekend picnics and long afternoons by the water, adding a genuine sense of community to one of the territory’s most famous beaches.
