Trail Overview

A rugged, tippy and bumpy climb to phenomenal views. Its short, so it's common to add a few other trails to your route to make a loop. ATVs, UTVs and dirt bikes will love this one. Open from May 21 to November 22.


Difficult. Very tippy, narrow and steep with several challenging rocky sections. Vehicles wider than 74 inches will find the last section of the climb especially nerve-racking as a small rock wall forces you toward the edge of the shelf road. Snow may block trail into mid summer.

Access Description

Get off Route 6 at east end of Keystone Ski Area following signs to Montezuma Road. (See map detail of exit.) Head south on Montezuma Road 5.2 miles where pavement ends. Continue into town of Montezuma. Unlicensed vehicles can stage south of Waypoint 02. You can also reach the bottom of Radical Hill from the south via Red Cone, Trail #76, or Webster Pass, Trail #77.
