Buck Island Wall, also known as Dive Flag Rock or Andres' Reef, is a reef wall on the north side of Buck Island off St. Thomas and one of the deeper dives on the island's list. Stingrays and eagle rays regularly cruise along it, and its two levels suit a multi-level dive.

Also known as Dive Flag Rock, Andres' Reef.

The dive

The top of the reef lies at 9 m (30 ft) and the sand at its foot at 18 to 21 m (60 to 70 ft). That spread lets the dive run on two levels, along the sand at the base of the wall and over the reef top above it.
