Alta ski area is now closed to uphill travel. The Summer road is open with access to Grizzly Gulch and Catherine's Pass.
Grizzly Gulch will be closed to all travel, Friday 2/26 from 8am–4pm, while equipment works to put in the Grizzly road.
Uphill travel is prohibited in the shaded area in the maps below:
During the ski season when we have 24-hour-a-day operations going on with avalanche mitigation, grooming, maintenance and downhill skiers, the only uphill travel area that we approve is on the Summer Road and Grizzly Gulch, when open. Any other uphill travel presents a safety issue for our employees and skiers and interferes with our operations and the product we prepare and sell to our skiers.
The Summer Road starts at the gate where Little Cottonwood Canyon Road ends and may be used to access Grizzly Gulch and Catherine's Pass. Generally, when the Summer Road is closed, you should be able to get to the south-facing slopes above the Town of Alta.
These areas are subject to temporary closures for the Utah Department of Transportation (UDOT), Alta Ski Patrol avalanche mitigation and/or other operational reasons. Trailhead signs will indicate when backcountry closures are in effect. Updates are also available online via UDOT Avalanche, the Utah Avalanche Center and Alta Central.
When traveling uphill on the summer road to access Catherine’s pass or in Grizzly Gulch please note the following:
- Backcountry conditions exist.
- Hazards are not marked.
- You are responsible for assessing avalanche hazard and risk.
- Please treat the ski area as backcountry terrain.
- Carry and know how to use avalanche gear.
- There is no ski patrol.
- You are responsible for your own rescue.
There is no access to East Castle from Dry Fork. If touring in the Dry Fork area, please re-enter Alta Ski Area via the Point Supreme.
