Uphill Access

Earn Your Turns by Skinning or Split Boarding Uphill

Skip the lift and get your lungs burning. We offer 3 uphill routes that are easily accessible from each of our base lodges – view the uphill trail map below. Be sure to be in the know of all uphill access rules and safety information, and check the uphill trail status for route closures, as well as weather and conditions reports before you start ascending.

Uphill Skiing Permitted During Operating Hours Only

8:30AM–4PM Daily (weather and conditions permitting)

Uphill Ticket Required

Available at any base lodge ticket window. All uphill skiers and split boarders must obtain a specific uphill ticket that allows uphill access on designated routes only; chairlift access is not permitted. Uphill tickets are only valid with use of authorized uphill-use equipment.

Authorized Uphill-Use Equipment

Skis & Split Boards

While ascending, only authorized uphill-use equipment can be utilized; snowshoeing, boot packing and hiking are not permitted. All skis, including Nordic and split boards, must be fitted with retention devices. Skins or climbing scales are required for skis and split boards while ascending.

Uphill Rules & Safety

Be Safe & Have Fun

We insist upon personal responsibility and respect for others and our environment. Prior to any uphill activity, it is your responsibility to check the trail status for any route closures, as well as weather and snow conditions. It is common for uphill routes and downhill trails to open and/or close any time during normal operating hour.

Mammoth works hard to provide a safe, consistent and fun mountain experience. To ensure a great day on the hill, please adhere to following uphill safety guidelines.

Uphill Rules

  • Uphill access is only permitted on designated uphill routes during ski area operating hours.
  • Be aware of your visibility. Avoid blind spots by remaining visible to all downhill skiers/riders, especially on steep terrain and below abrupt rollovers.
  • You must stay on the side of the ski trail while ascending; switchbacking across the trail is not permitted.
  • Use caution – snowmobiles, snowcats and snowmaking may be encountered at any time.
  • Never ski or split board over a snowmaking hose or power cable. If you encounter one in your pathway on an uphill route, you must backtrack to go around it.
  • Use of headphones is discouraged to ensure you can hear downhill skiers/riders as well as approaching snowmobiles, snowcats and other on-hill vehicles.
  • Never duck a roped or signed closure. Uphill users must never cross any snowmaking hose or power cable. 
  • You must stop ascending and head downhill if Ski Patrol closes the ski trails/uphill route in use due to changes in weather or conditions, or if you are still ascending at the end of the ski area’s operating hours.
  • Dogs are prohibited on the slopes. Only service
    animals are permitted at ski area facilities.


Know the Code

We’re committed to promoting safety. In addition to people using traditional alpine ski equipment, you may be joined on the slopes by snowboarders, telemark or cross-country skiers, people with disabilities using specialized adaptive equipment and others. Always show courtesy and be aware that there are elements of risk in skiing/snowboarding that common sense and personal awareness can help reduce. Know your ability level and stay within it. Observe the National Ski Areas Association’s “Your Responsibility Code” listed below to ensure a great day on the hill.

  • Always stay in control, and be able to stop or avoid other people or objects.
  • People ahead of you have the right of way. It is your responsibility to avoid them.
  • You must not stop where you obstruct a trail, or are not visible from above.
  • Whenever starting downhill or merging into a trail, look uphill and yield to others.
  • Always use devices to help prevent runaway equipment.
  • Observe all posted signs and warnings. Keep off closed trails and out of closed areas.


California State Penal Code

Uphill skiers and split boarders must obey all on-mountain signage, including roped or signed closures; entering closed terrain is prohibited and punishable by law. Those who enter a closed area will be suspended from the ski area for a minimum of thirty (30) days, and may be prosecuted. The following misdemeanors are punishable by a fine of up to $1,000. Violators will lose lift privileges.

  • Skiing/riding within or entering a CLOSED area. PC 602r.
  • Leaving the accident scene if involved in a collision, except to notify authorities or obtain assistance. PC 653i.
