Lost maples state natural area is located 5 miles south of vanderpool texas, about 2 hours northwest of san Antonio. One of the more scenic parks we have visited, the park is at its most beautiful in the fall, with all the maple trees turning shades orange and red. enjoy over 10 miles of hiking trials, with one loop taking you along the top of a 2,200ft cliff! Enjoy a swim, or wet a line in the crystal clear waters of the Sabinal river, and watch for the many birds that call the park home, including the endangered golden-cheeked warbler and the recently delisted black-capped vireo. Camp in one of 30 rv sites, or hike in to one of the many primitive sites.
