Hill Country Edge
In July 2002, a massive flood overtopped Canyon Lake's spillway and carved a 1.5-mile gorge up to 80 feet deep in just three days — exposing dinosaur tracks, ancient fossils, and rock layers formed 100 million years ago. The Guadalupe-Blanco River Authority runs guided hikes through the gorge on weekends (reservation required). It's one of the most geologically significant sites in Texas and remains relatively unknown.
Shade Details
The gorge bottom offers some shade from the canyon walls. Most of the hike is in direct sun. Morning guided tours are more comfortable in summer.
Conditions & Tips
Guided tours only — reservations required through GBRA. Tours run Saturday and Sunday mornings. Summer tours are hot; bring plenty of water.
