Above the Rock: Soaring Castle Rock’s EDGE Zip Line
A half-day of controlled flight over Colorado’s oak-and-pine ridgelines—fast, accessible, and rooted in open space
The morning air tastes like scrub sage and diesel—clear, dry, Colorado. You step out of the shuttle and your harness snaps snug against your hips; two guides run through checks with the efficient calm of people who live where exposure is everyday conversation. The landscape around you is honest and rugged: oak-and-pine ridgelines, wind-shaped rock outcrops, and a patchwork of 320 acres of protected open space that unfurls below. The ziplines don’t just cross land, they cross perspective—each run rearranges the scale of the plateau, the town, and the distant spine of the Front Range. For 2 to 3 hours, gravity is your locomotive and the guides, your conductors.
Trail Wisdom
Secure small cameras
Use a wrist strap or chest mount; loose phones are easy to lose in wind and speed.
Wear closed-toe shoes with grip
Trail runners or hiking shoes give you traction on platforms and while walking between lines.
Layer for variable temps
Mornings can be cool and afternoons warm; a lightweight wind layer stashes easily under a harness.
Hydrate before you arrive
Bring a small bottle; half-day tours have short breaks but limited time for long rests.
