Crystal caves are definitely worth it....lost river is cool but its a very very short tour.....its been awhile but i think the CC were about an hour...LR was maybe 25 minutes...both are good but id put your money on CC.
2 different caverns. Lost River is 7$ and the visit is 20 to 30 minutes. Crytal caves are 16 $ and 40 to 50 minutes. I enjoyed both.
Unable to compare. Never been to Crystal Caves but on my bucket list.
