Chutes and Ladders is a current-driven reef drift in Culebra’s protected channel reserve, known for the way the run starts by working into the current and then turns into a drift back across the reef. The route moves over coral heads, sand, and broken reef, so navigation stays straightforward even as the tide changes the feel of the dive. Plan on a boat drop and choose conditions carefully, because the current can swing from mild to strong. The reserve’s reef structure helps support turtles, reef fish, and rays.
