Blue Lagoon Lake is a great place to spend the day as a family. Located just outside of Huntsville,TX, this lake is perfect for divers and swimmers. There are no boats to worry about. The water is warm and clear. We found a great spot with some rocks that were fun to jump off of and swim around. There is no wildlife to be seen underwater due to the Ph balance of the water, but they have decided it is worth the trade off in visibility for divers. Even when the area is full, crowding does not seem to be a problem. There is a place to fill scuba air tanks as well as to get a few snacks. There are shelters and port-a-potties locate throughout. It is a really nice area to spend a day.
