Near the waterfall and for something out of the sun, take a hike to the popular Mai Kaeo Cave. Turn right off the paved road just after the mosque till you see the parking place. A guide from the family owning the land will take you up through rubber tree plantation and jungle over rope bridges to the cave entry.

Teh caves consist of a series fo spectacular chambers with rock stalagmites, stalactites and rock formations. It involves some climbing up and down of rope ladders but is not too strenuous.

When you spot people with muddy clothes and big smiles, they're just back from the caves.
