When I was in high school (Schertz Clemens), we used to go down in Cibolo Creek and have some fun, but they shut that down around 2001 or so. There also used to be a place called Devils Den, but it is shut down to motorized vehicles as well. That pretty much leaves you with heading out to Hidden Falls.
there is a place over off judson rd. and toperwein rd.. it's by rollin oaks mall. it might be the one place where the second reply was talking about, I'll check to see if it's still there.I'm working on a place to wheel out by my house.. farmers land, but alot of mud and hills-trails...
I haven't been to that one. I have been exploring the stone oak/cibilo canyons area.
If you go down the hill to the intersection of Evans there's a Walgreens on one corner and a CVS on the other. Turn left into the Walgreens and if you follow the pavement of the lot it turns into a dirt road. PM me if you ever want to go.
