- Ascent: 700 feet
- Difficulty: Moderate
- Hiking: Both directions
- Biking: Both directions for 2020; uphill only in the future
Argentine North Fork is A-Basin’s primary singletrack trail. It begins near Mountain Goat Plaza in the base area and ascends to Black Mountain Lodge at mid-mountain. Hikers and bikers will find wildflowers, scenic vistas and crystal-clear streams along the way. Mountain bikers can turn around at mid-mountain or continue climbing to the summit on Upper Summer Road.
Wheels Up: Bike-only DH trail
- Distance when complete: 2.5 miles (one-way)
- Distance available: 1 mile
- Descent: 700 feet (total when finished)
- Difficulty: Moderate

Wheels Up is our featured downhill, bike-only flow trail from Black Mountain Lodge to the base area. Full of berms, rollers and optional lines, this playground of a trail was built specifically for bikes. Wheels Up is suitable for intermediate riders (all features can be rolled) and extra-fun for advanced mountain bikers. Currently, one mile is complete. Climb ANFT to connect to Wheels Up for an awesome descent. Stay tuned for the full ride!
Summer Road, Upper & Lower
- Distance: 2.6 miles combined (one-way)
- Ascent: 1,676 feet total
- Difficulty: Moderate to difficult
- Hiking: Both directions
- Biking: Both directions
Summer Road is a steep and rocky service road running from top to bottom. The 1.3-mile Upper Summer Road begins at Black Mountain Lodge and takes you well above treeline. It is currently the only way to access the summit at 12,456 feet. Enjoy stunning views of A-Basin, Loveland Pass, multiple 14’ers and our resident mountain goat herd. We recommend using ANFT and Wheels Up on the lower half of the mountain. Please watch for vehicles!
Pali Road
- Distance: 0.6 miles (one-way)
- Difficulty: Difficult
- Hiking: Both directions
- Biking: Both directions
Pali Road is a very steep service road that takes hikers and mountain bikers from the Upper Summer Road (just above mid-mountain) to the top of Pallavicini Lift. From there, enjoy dramatic views of The Beavers and Pallavicini ski terrain.
COMING SOON: A HIGH-ALPINE SINGLETRACK ADVENTURE
We are working in conjunction with IMBA Trail Solutions on a 10- to 12-mile backcountry mountain biking loop that will be directional and mostly bike-only.
The loop trail will offer an intermediate to advanced, old-school cross-country riding experience on bike-optimized trails. The high-alpine loop trail will ascend from mid-mountain to 12,500 feet at the top of the lift-served terrain, head west traversing the ridgeline, descend into The Beavers ski terrain, and finish by crossing the top of the Pallavicini terrain before connecting to a bike-only downhill trail for the final descent. It is scheduled to be completed over the next few summers.
There are currently no plans for lift-served mountain biking.
LENAWEE TRAIL, OFF THE BACKSIDE
If you know, you know. We are famous for this gorgeous but difficult U.S. Forest Service trail. From the top, a skilled backcountry rider can descend the 3.3-mile, black-diamond Lenawee Trail one ridgeline east of A-Basin’s Montezuma Bowl, ending at County Road 260/Peru Creek Road. From there, connect to additional trails and dirt road riding, if so desired. Please note this is outside our summer operating boundary.
Lenawee is steep; it’s technical and it requires a shuttle or a big loop with significant time spent pedaling on roads. Please review the elevation profile and map before attempting Lenawee for the first time. It’s worth it the adventure if you are prepared. (Please be prepared!)
RENTALS? EMTBS? BIKE HAUL?
We do not offer bike rentals, beginner trails, mountain bike programming or bike haul on our lifts.
eMTBs (electric-assist mountain bikes) and motorized vehicles are NOT allowed on our singletrack trails. We are entirely on U.S. Forest Service land and that is a USFS restriction. You may ride them on the dirt roads, only.
Arapahoe Basin is located on Loveland Pass, the finish for Stage 2 of the 2015 USA Pro Challenge. The category 1 climb up Loveland Pass is a must-do for visiting road cyclists, combining a winding 8-mile climb with an exhilarating downhill on the scenic Continental Divide.
Loveland Pass is open to vehicles throughout the year, including tanker trucks, so please use caution on this roadway. You can get to Loveland Pass from the Summit County bike path system and enjoy lunch on the deck of the 6th Alley Bar & Grill at the Basin on your way back home!
