This is the Pecos River near Pandale (just South on Ozona).  I only rode around, and in, the river so I don't know if there are any trails in the area.  There are dirt roads all over the area and there is potential for some great riding.  This is also a great place to swim and fish if you like doing that kind of stuff.  There are no hotels but there are some cabins or you can camp..  There is a store/restaurant just up the road from the Pecos River but there is no gas to be found.  Be sure to fill up in Ozona before making your way down here.

    The surface under the water is solid granite so I didn't damage anything.

    After a good rain riding like this would not be possible.

    Be prepared to get wet, the rocks are slick.
