Expect winter conditions throughout the park. Snow amounts range from a few inches at 4,000 ft to over a foot at 6,000 ft and more at higher elevations. Though snow amounts may seem modest, even a little bit of snow can obscure all indications of a trail, making navigation difficult. Further, travel over snow is slower than hiking and can be very slippery at times. Snowshoes or skis should be used when planning on traveling over snow covered areas.
Be prepared for freezing temperatures at night and cold or cool temperatures during the day. Except for the lowest elevations and exposed areas, plan to camp in the snow. Winter storms can come at any time with heavy snowfall, making travel and navigation very difficult. Always be sure to check a current weather forecast before you start your trip and be prepared for a multitude of conditions.
Ski conditions are listed on the Tuolumne Meadows Ski Conditions page.
Due to increasing bear activity along the Snow Creek trail and the potential for bear/human interactions the area to the south and east of the footbridge [3.3 MB PDF] is closed to overnight camping. The National Park Service will continue to monitor the bears' activity and will re-open the area to camping as soon as possible. The trails and areas are open to day hiking.
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.
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, tentatively on July 25, 2016. (Check back for possible date changes.)
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.

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.
