Why this hike matters
A protected aquifer landscape inside the city.
Crownridge Canyon was the first City natural area developed through San Antonio’s Edwards Aquifer Protection ballot initiative. Its 210.5 acres protect a sequence of restored grassland, limestone slopes, wooded canyon bottoms, and aquifer-recharge terrain.
Canyon to canopy
The preserve’s signature sequence includes forested canyon bottoms, hillside vistas, restored grasslands, and a canopy-level bridge overlook.
Rare-bird habitat
Friends of San Antonio Natural Areas identifies the preserve as habitat for the endangered golden-cheeked warbler during nesting season. Observe quietly and remain on trail.
Route notes
Choose one loop—or link both.
Red Oak Trail
A 1.3-mile lower loop on stabilized base, rated Level 1 and designed to meet ADA accessibility requirements. It crosses Red Oak Canyon at the bridge.
Bear Grass Trail
A 0.6-mile upper loop on Level 4 natural surface. The official description rates it medium difficulty, with rocky ledges and a few steep slopes.
Linked outing
Walking both named loops produces an approximately 1.9-mile outing. Connector use, backtracking, and GPS recording can change the actual total.
Wayfinding
Carry the official map and follow posted trail signs. Do not interpret the linked mileage as a separately named City trail.
