Mona Island / Mona Passage

Mona Island, located in the Far West of Puerto Rico, is a remote, uninhabited protected island. It features 150 ft+ visibility, sharks, sea turtles, and untouched coral.

Diving is the primary activity on the island, with typical conditions including 100–150 ft+ visibility, pelagic sharks, and a requirement for a permit and liveaboard accommodation. The best time to visit is from February to April, when the passage is calm, although a permit is required year-round.
