Wilderness Conditions

June 23, 2015

General Conditions

A historically dry and warm winter in Yosemite has left most of the park snow free as summer begins. Snow remains only on the highest peaks but is quickly melting. Trails are clear of snow while water is plentiful throughout the park with almost all streams and creeks flowing at this time. Stage 1 fire restrictions are in effect.

With the arrival of summer, be aware of the current weather forecast as well as monitoring the weather when you are hiking. Afternoon thunderstorms are often a possibility in the Sierra. Thunderstorms can form rapidly and unexpectedly, bringing localized heavy rain, strong winds, much cooler temperatures and lightning. Additionally, summer can also bring high temperatures. To help prevent heat related illnesses or injures, be aware of the current forecast, avoid hiking during the hottest part of the day, drink plenty of water and eat salty snacks throughout the day.

Current Closures

Current trail closures are listed on the current conditions page.

The trail to Rancheria Falls is open only to foot traffic for an undetermined amount of time east of Wapama Falls due to a large rockfall.

See a map of trails that are currently cleared of downed trees. Be aware that though most trees fall in the stormy winter months, trees can fall at any time of year and may cover some trails that have been cleared.

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.

Food Storage

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.
