Best place to dive around the Houston area. Take I-45 North through Huntsville, TX...exit 123 and go right about 4 miles. Entrance is on the left, you’ll see a painted rock that says "Blue Lagoon".
No running water. Porta-potties. No changing rooms (except porta-potties). Several underwater training platforms. Used to be quarry. Two lagoons to choose from. Lagoon 1 is mainly used for training, while Lagoon 2 is used by existing divers.
