Boat ride

After walking past the deepest part of the cave, you walk down the slope of the mountain until you reach the huge cavern (larger than two football fields) that contains the entrance to the underground lake. They have built a large pier with four boats. The boats seat about 24 people each. They are large rectangular flat glass bottomed boats with seats along the edge. They had to move the pier downward because the water level has dropped about 60 feet in the last 3 years.
