About Grayson Highlands

Grayson Highlands is arguably the best summer bouldering in the Southeast — 1,000+ problems on Whitetop rhyolite (with metaconglomerate and quartzite mixed in) scattered across the high balds of Grayson Highlands State Park, southwest Virginia. Main bouldering sits at 1,370–1,494 m (4,500–4,900 ft) so it's cool when Chattanooga is 35°C. VB to V12+ across every angle. Rhyolite dries fast; the high-altitude condensation/fog rule can fire in humid weather but rock quality isn't fragile like sandstone. AVP Boulders area now permanently public thanks to Central Appalachia Climbers Coalition + Access Fund. Crashpad rentals $10/day at the park.
