The Beavers and The Steep Gullies

This terrain is closed for the season. Thank you for making 2018-19 an awesome first season for The Beavers & The Steep Gullies!

The Beavers & The Steep Gullies is Arapahoe Basin's newest terrain, added for the 2018-19 season, and includes 34 runs over 468 total acres for ability levels from intermediate through expert.

Approximately 339 acres of terrain in The Beavers are served by a four-person chairlift which opened in the 2018-19 season. Runs include two new intermediate groomed routes (steep blues), open bowls and some of the best glade (tree) skiing in Colorado.

The extreme terrain of The Steep Gullies (129 acres) is for experts only. All skiers using that terrain are required to hike back to the bottom of the Pallavicini Lift; this hike takes approximately 20-30 minutes.

Located to the west of the current ski area boundary, the new terrain added approximately 468 acres of skiable terrain to Arapahoe Basin, bringing the ski area’s total acreage to 1,428 acres. The new terrain accommodates a wide range of skiers, from intermediates to experts. 


About the Terrain


The Beavers

Terrain in The Beavers runs the gamut from intermediate (blue square) groomed runs to most difficult and extreme (black and double-black diamond) tree skiing. The terrain is rolling and varied, with open bowl skiing at the top and glades on the west side and the lower 2/3 of the terrain. Loafer and Davis are our new groomed intermediate runs in The Beavers.

The Steep Gullies

The Steep Gullies is the most challenging skiing at Arapahoe Basin. These steep, narrow chutes vary in pitch and width, and are rated as "extreme" (double-black diamond). All terrain in The Steep Gullies is designated as "hike back," meaning that guests must hike or skin back to the bottom of the Pallavicini Lift upon completion of their run.
