A-Basin Frontside + The Beavers
DRONES ARE NOT PERMITTED AT A-BASIN. This is a US Forest Service rule and is for everyone's safety. There are no exceptions -- including for personal or news media use -- without prior written consent from both the USFS and A-Basin, and payment of the required fee.
Molly Hogan is our learning area / ski school hill. Find it adjacent Mountain Goat Plaza (base area) at the bottom of the main lifts. Check out our lesson offerings.
The frontside greens and blues generally get steeper farther to skier's left. (EX: Sundance is steeper than Wrangler; West Wall is steeper than Powerline)
The blue runs in The Beavers (Loafer, Davis) are the most difficult blue runs on the mountain due to their pitch, length, variability, and snow conditions.
Visit our Terrain Status page for the most current info on what runs are open at A-Basin.
Scroll down for a detailed map of the East Wall hike-to routes.
Take virtual tours of all of our frontside terrain by visiting our Mountain Areas page.
Montezuma Bowl (A-Basin Backside)
The backside ski and snowboard trails are intermediate to expert.
Expert skiers and riders seeking untracked powder should explore the EX terrain below the lift. The return hike is only about 10 minutes.
Check out a virtual tour of Montezuma Bowl and the A-Basin backside trails.
East Wall Routes
Important East Wall Access Info
Experts, only. Enter through open gates only (do not duck ropes; you will lose your pass)
Observe all signage and closures
Rescue from this area can be difficult and time-consuming
Do not hike above the traverse except in designated areas (Willies Wide, Tree Chutes). See these bootpack routes on the main frontside map above
Expect hidden and unmarked obstacles, variable conditions, as with all expert terrain
This terrain is conditions-dependent and requires a significant amount of mitigation work. It can open/close at any time.
Marjorie Bowl is NOT part of Arapahoe Basin; it is outside our boundaries.
Check out a virtual tour of the East Wall, guided by one of our ski patrollers.
