Hundreds of thousands of visitors flock here each year to enjoy its matchless vacation facilities. They swim in the clear waters of the Frio River, scoot its rapids on inner tubes, rent pedal boats, and hike its fascinating nature trails. On long summer evenings, young folks (and the young at heart) meet at the concession building for jukebox dancing every night during the summer season. Nearby is a miniature golf course, which is lighted for nighttime playing. Meals and snacks are served in the concession building, though many families prefer to take advantage of the many camping sites and do their own cooking. A limited number of cabins are available for rent. The park offers camping, hiking, nature study, picnicking, canoeing, fishing, swimming in the Frio River (unsupervised), seasonal miniature golf, paddle boat and kayak rentals (mid-March through Labor Day weekend), bike riding (surfaced).
Amazing hiking trails. Lots to do here. The views where breath taking. The hike up to old baldy was worth the trip. There are trails to fit every style of hiking. Enjoyed the Donovan trail and campos trail. Crystal cave trail gets a bit crowed with hikers. But still a nice trail. Bridges trail is moderate, up hill. The frio canyon trail is the least traveled trail. The water is crystal clear. Would go back here in a heart beat. Truly amazing park.
