I've hiked Half Dome for 20+ years: here's my playbook for landing the permit, gearing up, and safely handling the 400-foot cables.
You can do Half Dome as an overnight hike, and there are many options, but the most common is to overnight at Little Yosemite Valley, roughly halfway to Half Dome.
The ranger check is usually right before the Sub Dome.
Permits can be hard to get, and rangers do check for them.
You can technically hike Half Dome whenever you want, but the poles and boards you see here are only installed from late-May to mid-October every year.
You need to account for these 2026 closures depending on when you hike Half Dome.
