Sand Castle on the Beach This welcoming “castle” has two distinct faces: breezy suites and villas on the ocean side are steps from the pool, beach, and the Beach Side Cafe, which serves three meals daily and is a popular gathering spot for sunset cocktails. Across the street is a private enclave with hotel-style rooms surrounding a clothing-optional pool. Which ever option you choose, you’ll find Sand Castles to be a fun and friendly place to spend a few nights in Frederiksted.
