About FRR

Flat Rock Mountain Biking Ranch is now CLOSED for HUNTING SEASON! We re-open January 1, 2019.

Flat Rock Ranch is located in the beautiful Texas Hill Country about 45 miles Northwest of San Antonio. The ranch consists of 1,300 rugged acres that have been in our family for over 100 years. It is part of the original ranch founded by English architect Alfred Giles in the 1880's. In fact, we still raise Black Angus cattle and Angora goats.

Currently we have 28 miles of existing single track with some double track. The trails lead through typical hill country terrain, with spectacular views, hill climbs, long downhill sections, technical single track, and several creek crossings.


Flat Rock Ranch closes for hunting season. Last day to ride is usually the last weekend of October. Exact date will be announced through social media. When we re-open January 1st, our hours of operations will be from sunrise to sunset. Please call in advance to schedule night riding.  

For other things to do in the area check out the Comfort Chamber of Commerce.
