Lexington Arch
Towering limestone arch above Lexington Canyon—geologically rare, carved by weather from a possible cave passage.
Natural Attraction
Towering above Lexington Canyon floor, this striking limestone arch creates an unusual geological spectacle—most western natural arches form in sandstone, but Lexington Arch's limestone composition hints at a different origin story. Evidence suggests this arch may have once been a passage in an underground cave system, with flowstone deposits at its base offering silent testimony to subterranean water activity. Weather has carved this formation over centuries, gradually sculpting the limestone into the graceful span visible today.
Getting there & parking
- How To Get There
- The approach begins with 0.5-1 mile of walking on a washout-damaged road before reaching the official trailhead. From there, the trail climbs 2.7 miles to the arch base (5.4 miles round trip total). The final quarter mile features switchbacks and elevation gain to reach the opening.
