Stillhouse Recreation Area (REC) · Open Access

Union Grove Park is located on the southwestern shore of Stillhouse Hollow Lake in central Texas. The lake offers a wide variety of recreation opportunities, including water sports, hiking, biking, horseback riding, picnicking, large group pavilions, hunting, fishing and simply enjoying the scenery. This facility has RV and tent camping sites with water and electric hookups available. The facility is one of only two reservable campgrounds on the lake. Stillhouse Hollow Lake was created by the U.S. Army Corps of Engineers with the construction of Stillhouse Hollow Dam in 1968. The 6,430-acre lake is located 16 miles upstream of the confluence of the Lampasas and Leon Rivers, which flow into the Little River.
With 58 miles of shoreline, Stillhouse Hollow Lake is an often uncrowded haven for boaters and fishermen. The campground has a four-lane boat ramp, and visitors who do not have motor boats, canoes or kayaks can rent them nearby. Birding is also a favorite pastime, with hawks, Great Blue herons, ducks, geese, many species of songbirds, bobwhite quail, Rio Grande turkey and even an occasional bald eagle, yielding year-round opportunities for bird sightings.
The campground has more than 30 campsites, including RV and tent sites with electric hookups and double sites. The park offers restrooms with flush toilets and hot showers, a fishing dock and a boat ramp.
Not recorded upstream: grills.
