Mountain Areas The Front Side

A-Basin’s front side terrain offers a little of everything, from the most casual runs to advanced moguls to the three terrain parks. Most of the Basin’s intermediate routes and all on-mountain beginner runs are accessed via this area’s Black Mountain Express and Lenawee lifts. 

The Legend’s front-side skiing and riding is still a big-mountain experience. Two, short lift rides and you’re at 12,500 feet—above treeline at the top of the lift-served terrain—exploring wide-open intermediate groomers and introductory glade runs. The front side lifts also offer access to the rest of the mountain areas, making A-Basin extremely easy to navigate.


  • EASIEST WAY DOWN: Wrangler to Chisolm. Sundance is a steeper green. 

  • FIRST TIME ON BLUES: Lenawee Face --> Dercum's Gulch --> High Noon

  • MOGULS: Exhibition, Ramrod (Looking for serious moguls? Get on the Pali Lift)

  • EASIEST TREES: Easy Gully, Cabin Glades, Lynx Lane

Please note that the green-blue-black trail ratings are relative to an individual ski area's unique terrain. Some of our greens and blues might be steeper than what you're accustomed to. If you're just starting out, please visit our Molly Hogan learning hill. 

The Beavers and The Steep Gullies

The Beavers and The Steep Gullies are 468 acres of terrain added in the 2017-18 season, growing A-Basin’s skiable area by nearly 50 percent. Construction was done with minimal environmental impact and completed the vision A-Basin’s founders had back in 1946. A quad lift gives you access to 36 runs in The Beavers, including rolling intermediate groomers, open bowls, steep chutes and some of the best glades and powder stashes in the state.

  • Please note that the two blue runs in The Beavers are considered to be the most challenging blues on the mountain. 

  • WHEN DOES IT OPEN? Late November - late December (Beavers). The Steep Gullies require significant snow coverage and avalanche mitigation work. Expect that terrain to open late winter. 

The Steep Gullies is as-advertised and features expert-only terrain comprised of steep, narrow and rocky chutes. This is some of the most challenging in-bounds terrain you'll find in the state. Skiing or riding it requires serious skills and commitment, followed by a 20-30 minute hike back to the base area.  


Montezuma Bowl

“Zuma” was A-Basin’s first major expansion, completed in 2007-08 season, and grew the mountain’s terrain by 80 percent. This south-facing backside bowl offers stunning mountain scenery including views of multiple 14,000-foot peaks. The terrain is home to 400 acres of wide-open intermediate groomers, well-spaced trees and rocky cliffs. A small hike-back zone below the lift almost always guarantees great snow and solitude. 

  • EASIEST WAY DOWN: Larkspur --> Independence

  • EASIEST TREES: Miners Glade

  • WHEN DOES IT OPEN? Mid December - mid January



The Pallavicini area is A-Basin’s legendary, front-side advanced and expert terrain. Served by a lift of the same name, the primarily double-black Pallavicini runs are accessible directly from the base area with a single lift ride. Don't miss The Spine, one of our favorite runs on the mountain. 

Pallavicini has also been hosting the A-Basin Enduro for 30 years. During the event, teams of two ski and ride as many runs as possible off the “Pali Chair” over 10 consecutive hours to help raise funds for a community member in need. 

WHEN DOES IT OPEN? The lift usually starts turning after Thanksgiving. The steep terrain requires more snow coverage than other parts of the mountain. Not all of the runs open right away or at the same time.


The East Wall

A-Basin is an adventurous mountain and to hike the East Wall is to experience one of The Legend’s biggest adventures. Make your way to 13,050 feet to enjoy the ski area’s most iconic views and some of its most extreme terrain. Access the East Wall chutes with just two, short lift rides, then use the hiking routes to spend an entire day (or lifetime) exploring.

Important information for skiing / riding The East Wall

  1. Enter through gates only (do not duck ropes)

  2. Observe all signage and closures

  3. Rescue from this area can be difficult and time-consuming

  4. Do not hike above the traverse except via designated bootpacking routes (Willies Wide, Tree Chutes)

  5. Expect hidden and unmarked obstacles

  6. This is expert-only terrain

WHEN DOES IT OPEN? The East Wall requires significant snow coverage and avalanche mitigation work. It usually opens in February, beginning with terrain below the East Wall Traverse. Sometimes it opens in January, sometimes in March. The East Wall is conditions-dependent and can open/close at any time. 

Molly Hogan (Learning Area)

Molly Hogan is A-Basin’s learning hill at the base of the mountain. Easily accessible from the lodge, Snowsports headquarters and the rental shop, the area is served by two magic carpets and one lift. Molly Hogan has welcomed multiple generations of fresh faces to The Legend not just teaching them to slide on snow, but transforming them into skiers and snowboarders. When you learn to ski or ride here, you can ski or ride anywhere!

WHEN DOES IT OPEN? Early to mid November.
Ski + snowboard lessons start mid-November
