General Conditions
Autumn has arrived in Yosemite. Temperatures are dropping and the potential for snow increases with each passing day. After a long hot and dry summer, recent rains have reinvigorated creeks that had dried up.
Visitors should be prepared for a wide variety of conditions. Conditions can vary from sunny and warm to frigid with early season snow storms. Expect that temperatures could drop well below freezing. Even the smallest amount of snow can obscure the trail and make travel difficult. Always check a current weather forecast and be prepared for any type of conditions.
Beginning October 15, overnight parking is not allowed anywhere along the Tioga Road between Tuolumne Grove and Tioga Pass; this includes all parking area, turnouts, and side roads accessed from Tioga Road. Overnight parking is also prohibited along Glacier Point Road (including Glacier Point).
| Area Specific Conditions | ||
| Park Area | Locations | Trail Conditions |
| North and South Rim of Yosemite Valley | Yosemite Falls, North Dome, Dewey Point, McGurk Meadow | With recent rains, Yosemite Creek, Indian Canyon and Lehamite Creeeks are flowing again. Snow and Cascade Creeks continue to have water in them. The camping closure between the top of the Snow Creek switchbacks and the Snow Creek footbridge is still in effect: there is no camping allowed in that area. On the south rim, Meadow Brook and Bridalveil Creek are flowing. |
| Glacier Point Road | Ostrander Lake, Illilouette Creek | Water is available in Triple Peak Fork, Merced Peak Fork, Bridalveil and Illilouette Creek. Water is available in lakes. |
| Wawona Area | Chinualna Creek, Buena Vista Loop | Chilnualna Creek is flowing. Water is available in lakes. |
| Hetch Hetchy | Beehive Meadows, Laurel Lake, Jack Main Canyon | Hetch Hetchy is hot and dry. Plan to carry water between the larger water sources. The only water source from Hetch Hetchy to Lake Vernon is the Beehive Meadows spring |
| Tuolumne Area: South of Tioga Rd | Lyell Canyon, Rafferty Creek, Ireland Lake, Fletcher Creek | Rafferty Creek is dry. Echo Creek is flowing on trail between Sunrise and Merced HSC but dissapears before Echo Valley. Water is available in Lyell Canyon. Fletcher and Lewis Creeks are flowing. |
| Tuolumne Area: North of Tioga Rd | Glen Aulin, Cold Canyon, May Lake, Murphy Creek & Polly Dome Lakes | Murphy Creek is dry. Cold Canyon has standing pools of water. The larger creeks in the northern canyons are all flowing. The only available water between Harden Lake and Pate Valley is from a spring just before Harden Lake; no water in Morrison Creek. Both the bridge to the Glen Aulin backpackers camp and the bridge crossing the Tuolumne River in Pate Valley are out. Conness Creek must be crossed to access Glen Aulin HSC- flow is very minimal. The Tuolumne River must be crossed to access Pate Valley from the Grand Canyon of the Tuolumne. Water flow is low. |
| Tioga Rd: West | Half Moon Meadow, Ten Lakes, South Fork Cathedral Creek | Standing pools only in the South Fork of Cathedral Creek. Water still available in tarns and creeks below Tuolumne Peak. One small creek is flowing between Tioga Rd and Ten Lakes. |
| JMT (Happy Isles to Tuolumne) | Little Yosemite Valley, Sunrise Creek, Sunrise HSC, Cathedral Lakes | Bears have been very active along the JMT corridor. Please store food (and toiletries!) properly to prevent them from obtaining it. Store bear canisters outside backpacks to avoid property damage. Sunrise Creek is flowing. There is limited water availability in the Sunrise HSC area. There is no water in Long Meadow and only a few inches remain in the creeks surrounding the HSC. These are not reliable water sources. |
The bridge to Glen Aulin High Sierra camp is out and will not be installed for the 2018 hiking season. Please be prepared for an unbridged creek crossing.
The bridge over the Tuolumne River is Pate Valley is out and will not be installed for the 2018 hiking season. It is not recommended to hike this route. With fall here and water levels lower, there is a possibility of crossing at an alternate site significantly downstream. As the crossing is over a river, not a creek, and an alternate crossing site must be found, this should only be attempted by experienced hikers.
See a map of trails that have been cleared of downed trees for the season. Please note that though most tree failures occur during the stormy winter months, trees can fail at any time.
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 6, 2018.
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.
