Family of 4, with 2 teens, we are thinking about going to Hot Springs at the end of July, or first part of August for a 3 day weekend. One day we would like to go crystal mining. Are we crazy to do this in the heat of the summer? Has anyone gone recently and which mine(s) do you most recommend. We are thinking of the Clarion hotel because it is right on the lake. Any other suggestions welcome. Thank you.
