Trevor’s Rocks - Poor Knights Islands

Arrecife Norte offers a decent wall dive, starting shallow at 8 meters before dropping to 15m. From there, it’s a gentle slope down to 24 meters, navigating between coral mounds. The reef here is healthy; we’ve spotted plenty of reef fish, and occasionally a nurse shark or stingray cruising by. Visibility averages around 11 meters, so it’s not always crystal, but it’s a good spot for a relaxed dive if you’re looking for a bit of wall action in the Tayrona area.
