Climbing the South Face
Take the Durango and Silverton Narrow Gauge Railroad to Needleton, then backpack 6 miles to Chicago Basin. The summit block requires short but precise Class 4 moves with significant exposure. The final moves can be intimidating for those uncomfortable with heights. Often combined with Windom and Eolus for an ambitious Chicago Basin tour. Plan for 2-3 days in the basin. Train reservations are essential in summer and fill up weeks in advance. Spectacular wildflowers in July. One of Colorado's most dramatic and remote 14er settings.
