Best Time for Chobia Pass Expedition — Month-by-Month Guide
Mid-June to early October. Earlier crossings face massive snow accumulation.
Pass Window
When is it climbable?
The trekking window is microscopically small. It is exclusively an end-of-summer and early-autumn route. Attempting it outside of a 6-week window in late August and September invites overwhelming risk.
Season at a Glance
Editor's Notes
September allows you to visibly see the black cracks of the crevasses against the white ice. In early summer, they are hidden under soft snow, framing lethal traps.
