The Franklins are the largest sustained mountain range in Texas, with the summit of North Franklin Peak rising to an elevation of 7,192 feet, approximately 3,000 feet above the city below. On the eastern flank of North Franklin Mountain lie the remnants of our nation's only tin mining, milling and smelting operation, which was active from 1910 through 1915.Two hiking trails are currently accessible off of Loop 375/Trans-Mountain Road. Work is underway for a trail network that will ultimately offer a system of more than 100 miles of trails. Rock climbing is one of the park's newest recreational activities, with established climbing areas in McKelligon Canyon.
A limited number of primitive tent-camping sites are available in the Tom Mays Unit. Traditional sites allow for tents placed on the ground. Five self-contained RV sites have also been added. All potential campers should be forewarned: there are no ground fires allowed within park boundaries and no water or electricity supplies. Those desiring camping reservations may contact the park office. Reservations are recommended.
