A historically dry and warm winter in Yosemite has left much of the park snow free as spring arrives. Snowline is roughly 8,000 ft, depending on the aspect, vegetation and micro-climate. For example, a forested north facing slope may still have some snow at 7,500 ft while an area of open granite on a south facing slope could be snow free at 8,600 ft. Be prepared for consistent snow coverage above 9,000 ft.
Although it may seem like summer, the weather can change abruptly. Be aware of the current weather forecast as well as monitoring the weather when you are hiking. Late season winter storms can come at anytime and bring much colder temperatures, significant snowfall or rain and strong winds. Winter storms pose a hazard to hikers.
Current trail closures are listed on the current conditions page.
Trails in Yosemite may be closed when there are hidden hazards or are impassable due to rock fall, snow, ice, or fire. Open trails are not necessarily free of hazards. By entering the wilderness, you are assuming responsibility for your safety and must use good judgment.
Free wilderness permits are required for overnight stays in the Yosemite Wilderness. Permits can be obtained at the following locations.
Wilderness Permit Reservations
The reservation office is open for the season. Reservations are available up to 24 (168 Days) weeks ahead of your entry date.
Yosemite Conservancy staff will be available Monday to Friday to process wilderness permit reservations for this year. Fax is still the preferred method for reserving wilderness permits. The fax machine is functioning well and is receiving permit applications as fast as we can process them.
Approximately 90% of permit applications for the John Muir Trail are rejected due to too many requests for the same trailhead on the same day.

Bear resistant food canisters are required in the Yosemite Wilderness. Use a canister to store all food or scented items when left unattended. Remember that anything used in, on, or around the body is considered a food item. Whenever food or scented items are out, please keep them within arm's reach, even while day hiking.If a bear approaches your camp, act immediately to scare it away. Maintain a safe distance while making as much noise as possible. Throw small stones or pines cones toward the bear, being careful not to strike the bear on the head. If the bear returns, repeat. Do not attempt to retrieve food or gear from a bear until it abandons the items.
