Northwest of San Antonio near Bandera, the 5,369 acre Hill Country State Natural Area in Texas Hill Country has a wide variety of terrain and a mixture of single track and old jeep trails totaling 40 miles. Hillier than Austin, which is about two hours away, Bandera offers some longer climbs than Austin cyclists are used to, which in turn means some lubed downhill rewards. Moco miles of well-marked trails, an excellent swimming hole and some of the best enchiladas in the state will send you home from this day with a big silly grin. Bandera is the heart of Dude Ranch country so remember that bikers always yield to horses. There are a ton of trail options here so there are rides for all levels. Stick to the double track lower elevations trails for easier rides or pick out a killer loop with lots of single track and hills for a difficult grunt.
Make sure to check out the Three Sisters Trail if you are looking for a challenge. It climbs 2,000 feet over 5 miles.
