Season & Weather Guide
Mid-June to early October. Earlier crossings face massive snow accumulation.
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.

Important Tips
Late September is paradoxically safer because the snow bridges over the crevasses have melted, allowing you to clearly see and navigate the massive cracks in the ice.
