Glacier Point to Little Yosemite Valley: Early October Permit Notes

This permit covers the zone starting at the Glacier Point trailhead and dropping into Little Yosemite Valley, the staging area most people use for Half Dome, Clouds Rest, or a loop back down through the Mist Trail. In early October you're in the real shoulder season — the summer crowds have thinned but the route is still a known quantity, so don't expect to have it to yourself. This is a reservation-based zone permit through recreation.gov, not a walk-up or lottery system, so get your dates locked in as soon as you know your window. Availability tightens up on weekends even in fall, since this is one of the more popular exits out of Glacier Point and feeds directly into Half Dome traffic. If Half Dome is part of the plan, check the cable status before you build your itinerary around it. The cables typically come down for the season by mid-October, weather dependent, and once they're down the summit scramble is off the table for most hikers. Don't assume you'll get up there just because you have a permit for the zone. Water in October is thinner than summer. The Merced River corridor through Little Yosemite Valley is your reliable source for camp, but the smaller seasonal creeks and the upper stretch near Illilouette can be low or dry depending on how the fall has gone. Plan your refill points around the river and don't count on anything upstream of it. Temperatures swing hard this time of year. Days at Glacier Point elevation can still feel mild and sunny, but nights drop below freezing fast, especially once you're camped near the river in the valley bottom where cold air pools. Pack like you're camping in winter at night and hiking in fall during the day. Bear canisters are required for every overnight stay in this zone, no exceptions, and that rule holds regardless of season. If you don't own one, most outfitters near the park and ranger stations near the trailheads rent them, but don't show up planning to buy one on the fly — carry it in from the start. On timing: days are shorter now than they were a month ago, and the drop from Glacier Point into Little Yosemite Valley involves real elevation loss through forest and granite switchbacks. Start early enough that you're not finishing the descent in the dark, especially if you're also carrying water and food for a multi-night stay. Common mistakes people make on this route in fall: underestimating how cold it gets once the sun drops behind the valley walls, assuming Half Dome cables will be up without checking, and not carrying enough warm layers because the midday weather at the trailhead felt mild. Also watch footing — early cold snaps can leave icy patches on exposed granite sections even when there's no snow on the ground yet. If you're doing a loop that includes the Mist Trail on the way out, know that fall means lower flow at Vernal and Nevada Falls compared to spring and early summer, so the trail is less slick but also less dramatic. Either way, this is still one of the better multi-day combos in the park for granite scenery, waterfalls, and a real sense of elevation change without needing a full high-country permit. — Compiled by the PermitSnag team from agency info, ranger updates, and public trip logs.
