Dad's Notes:  Dripping green fern-canopied cliffs, sporting a breathtaking waterfall display into a deep, clear pool. Easily one of the most incredible sights in Texas. You can swim in the natural pool - it is not treated and no lifeguard, but you may find the sheer beauty calls you into the water!
     For effect, I recommend going during the week in the spring or fall (not crowded then). Swimming is not always allowed depending on the water quality - call ahead. Oh, and bring a camera to this one! The beautiful wilderness water trail is about a mile from the pool down to the river and back. (good shoes recommended)
     Bring water and a picnic - no drinking water or other concessions available. Parking capacity is 75 vehicles - so call ahead or go early if on the weekends!
     This pool and trail are protected habitat of endangered and rare plants and animals. So they ask you not bring dogs, glass bottles, no fires, no camping, no fishing and dont take anything from the site. This is a be sure not to miss site for the soul!
     Site/trail maps are available at entry. Picnic areas near the parking lot or you can carry down the steep trail to the pool. They also have special guided nature tours on Sundays @ 10a, call ahead.
