Emily and Albert Friedrich Wilderness Park features 600 acres of undeveloped Hill Country terrain, with over 10 miles of paved and unpaved trails. Trails are graded at varying difficulties, including wheelchair-accessible segments. The park is home to two federally listed endangered songbirds—the Golden-cheeked Warbler and the Black-capped Vireo. To protect Friedrich Wilderness’ trails and ecosystem, dogs, and bicycles are not permitted.
