That's weird I've always wondered if one could go there but I don't see any access roads to it. There are some driveways for some houses there but they say no trespassing other than that there is no other access to those lakes and trails. So I think these are not open to the public. Says Local
This lake is so wonderful. This lake is so wonderful. Catch full-scale fish at close by Austin Fishing Service, and perfect family excitement is in store for
you at Zone Action Park. Bentsen-Rio Grande Valley State Park is a great site to go if you're at Bentsen Lake, and you'll possibly meet some folks from Mcallen here.
