Houghtong Falls is a land and water tour. The sandstone features on the water are mainly mermaid rocks which are large sandstone chunks that are mainly beneath the water but come up above the surface enough for you to get out and sit on them, like a mermaid. There are 2 small caves on this tour but the true highlight are the waterfalls on land. The Bed of the creek at Houghton Falls is all sandstone. It’s an amazing reality to walk through the bed of an ancient sandstone river, it’s like walking through sea caves, but no kayak necessary.
