High Water Caution

Streams are running high and many are too dangerous to cross. Streams which are crossable in the morning may rise to unsafe levels by afternoon. Don’t get caught on the wrong side of a stream. If you must cross – scout out the safest location, the best crossing may not be in the exact location where the trail meets the stream. Above all use caution and be safe around all streams. Yellowstone’s backcountry does not have many bridges, please evaluate planned travel routes for any potentially hazardous stream crossings.

Snow Levels

Yellowstone has had above average snow fall this year which will result in delayed access into many areas of the backcountry, as well as above average river levels. Click on this link to find out more about current snow levels in the park.

Bear Management Area

In order to reduce human related impacts on bears in high density grizzly bear habitat the park has established several bear management areas.

Please reference the Bear Management page for further details and locations of closure area .

Ticks are out. After your hike check your body for ticks. Visit the CDC website for more information.

Fishing Season

The general fishing season is open. Some areas are closed until July. See the fishing regulations for more information.

Boating Season

The boating season is open. All watercraft (boats, float-tubes, stand-up paddleboards, etc.) must have a permit and a free Yellowstone aquatic invasive species inspection.

Horse Use

Some trails are currently open for day riding use only. Other trails for day riding will open as conditions allow. Trails currently open: Blacktail Deer Creek, Hellroaring, Garnet Hill, Specimen Ridge, and Coyote Creek.

Overnight horse use is closed until July 1st.
Check the specific trails below to see if they are opened for day use. Make sure to review our horseback riding page.

Food Storage Reminder

Do not leave food unattended at any time. All food, trash, and odorous items must be properly stored (hung 10 feet above ground and 4 feet from side supports or kept in one of the installed metal bear proof boxes, or an approved bear resistant food container) whenever the items are not in immediate use. Day hikers should keep their packs with them at all times. In past years, there have been several instances of bears obtaining food from unattended packs. Backpackers should hang their food immediately upon entering their campsite – before setting up camp.

Food Caches are not allowed in the backcountry. Hanging food overnight in an unoccupied campsite or elsewhere is not permitted – this is considered unattended food. Yellowstone allows only the use of certain bear resistant food containers.
