South Texas Edge
Purgatory Creek Natural Area protects 900+ acres of Balcones Escarpment cedar-oak woodland on the edge of San Marcos, about 45 miles northeast of San Antonio. The trail network is particularly popular with mountain bikers — technical limestone singletrack through dense cedar makes for challenging riding. Hikers share a subset of the trails. The preserve sits on critical golden-cheeked warbler habitat and is excellent for spring birding.
Shade Details
Dense cedar provides heavy shade on most trails. Actually one of the cooler summer trail options — cedar canopy blocks direct sun effectively.
Conditions & Tips
Spring is best for birding (April–May for warblers). Mountain biking trails can be technical — full-suspension handles the limestone better. No facilities; bring water.
