This is cliff jumping at sand hollow. The cliff we were jumping off of was unique because it was diagonally shaped so you could jump off at different heights depending on how manly you are. The first time I went I started at the lower parts then worked my way up to the top. But you didnt know for sure how high you jumped because the water would often rise or fall. Im not sure why it does that. We also went tubing here for a high adventure I went on its a great place. I got a really bad sunburn spending two whole days on the lake. The cliff was estimated to be about 40 ft tall.
