Take an ancient Quarry, let rain water fill it up a bit, call it "Grand Canyon", and charge 50 BHT entrance, which includes a free herbal drink (tastes good whatever it is). Cache is well outside, no need to go in. Good photo ops from outside as well.
Located on a popular bicycle route, with many old quarries and large raches.
