Kearsarge Pass Entry Permit: Mid-July Notes for Onion Valley Access to the JMT

Kearsarge Pass out of Onion Valley is one of the busiest side doors into the John Muir Wilderness, and mid-summer is when it sees the most traffic. JMT thru-hikers use it constantly as a resupply exit and re-entry point, and it also feeds into loop options deeper in the wilderness. If you're picking up this permit for a July or August start, plan around the fact that you're sharing the trail with a lot of long-distance hikers timing their food drops. This is a reservation permit through Inyo National Forest, managed on recreation.gov as a zone entry. There's no quota number or fee listed for this specific window in our data, so don't guess at numbers when you book — just get into the reservation system directly and lock your entry date and group size there. Walk-up availability on Kearsarge in peak summer is thin at best, so treat the online reservation as your real shot, not a backup plan. Trail conditions this time of year are typically snow-free from the trailhead to the pass, with the route climbing steadily out of Onion Valley through switchbacks before topping out on the pass itself. By mid-July the worst of the snowmelt runoff is usually behind you, but afternoon thunderstorms are a standard feature of the Sierra summer pattern — start early enough that you're not exposed on the switchbacks or the pass itself when storms build. We don't have a specific water source list for this stretch, so don't count on a fixed set of named creeks. Check the trailhead kiosk or ranger station for the current water report before you go, and carry enough to get through the dry sections comfortably rather than banking on a reliable source at a specific mile marker. Bear canisters are required, not optional, for anywhere in this zone — John Muir Wilderness is a hard canister zone, and the requirement applies above roughly 9,600 feet in most areas here, which covers nearly this entire route. There are no bear boxes at the trailhead or along the way, so your canister needs to hold your food from the first night on. Rangers do check at trailheads during peak season, and getting turned around because you're carrying a soft bag instead of a hard canister is a completely avoidable mistake. Common errors on this route: underestimating the elevation gain right out of the trailhead parking lot, not accounting for altitude if you're coming straight from sea level, and assuming your reservation covers a walk-up buffer day if weather or fires shift your start. Build in slack where you can, and always check current alerts for the forest before you drive up, since access points like this one can be affected by conditions that change fast in a fire-prone summer. If you're using this as a JMT exit for resupply, coordinate your permit dates with your food drop logistics in Independence or Bishop ahead of time — this is not a stretch where you want to be improvising once you're at the pass. — Compiled by the PermitSnag team from agency info, ranger updates, and public trip logs.
