Fort Mason City Park

This 125-acre municipal park offers camping, nature trails and mountain biking opportunities in the northwest portion of the Hills. RV sites also are available. No water to speak of here, but you could head down the road to the Llano River at the intersection with Highway 87 at Keller's Store if you want to rent a couple of kayaks for a paddle trip down to Castell. They are located on US Hwy 87 1 mile south of Mason.
