Wilderness Conditions Update

August 7, 2020

General Conditions

Summer backpacking is in full swing. Trails are generally clear and dry. Due to the lower than average snowpack this year, water availability in the backcountry is not as plentiful as early summer and some water sources marked on the map have dried up. This includes seasonal water sources and spring run-off drainages. Some areas of mud do still exist in Yosemite Wilderness- please stay on the trail to mitigate resource damage.

Summertime can be hot in Yosemite. Be prepared for hot temperatures; bring plenty of water, eat salty snacks, and try to avoid hiking during the hottest part of the day. Afternoon thunderstorms can happen any day throughout the summer. Thunderstorms can form rapidly and bring heavy rain, localized flooding, strong winds, much cooler temperatures, and lightning. Backpackers should check a current forecast before heading out on their trip and know how to read signs of incoming weather.

Stage 2 fire restriction are in effect for all of Yosemite Wilderness. This means that wood fires are not allowed in the backcountry. This includes fires used for warmth and cooking. Liquid, gas, and jell based stoves are still allowed.

Bears have been active in Yosemite Wilderness and bear incidents (a human encounter with a bear) have occurred. Backpackers must be vigilant about storing all scented items properly in a hard sided bear canister. Store bear canisters outside backpacks to avoid property damage and never leave food unsecured.

Due to COVID-19 there are many changes to normal operations inside Yosemite this summer. Wilderness permit issuance, wilderness center hours & operations, bear canister rentals and public transportation will be much different than in years past. Please read all guidance carefully before arriving.

See a map of trails that have been cleared of downed trees for the season. Please note that although most tree failures occur during the stormy winter months, trees can fail at any time.

Park Area Trails, (landmarks included in description) Trail Conditions

Current Closures

Current trail closures are listed on the current conditions page.

Kerrick Meadow is closed each year to padstock grazing to reduce impacts to the federally-threatened Yosemite toad and endangered Sierra Nevada yellow-legged frog. The area will temporarily reopen to grazing on August 15, 2019.

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.
