Leviathan Peak Overview

Leviathan Peak is located 0.7 northeast of the centennial thirteener Jagged Mountain. Jagged Mountain is composed of solid granite, but Leviathan is made of 3rd class quartzite slabs. Leviathan Peak is the 236th highest peak in Colorado and the 183rd highest thirteener in the state. Leviathan is rarely climbed. Prior to August 5th, 2007, the most recent entry in the summit register was in July of 2006. When Leviathan Peak is climbed, it is usually by its southwest ridge. Leviathan’s southwest ridge can be accessed many ways: Purgatory Trailhead, Vallecito Trailhead, Beartown Trailhead and Needleton Trailhead. Starting at the Needleton Trailhead appears to be the easiest approach and is described below.
