Mountain Bike Trails Near A-Basin

Lenawee Trail

lenawee trail arapahoe basin

A-Basin is where you start your climb to access the Lenawee Trail, a famous and scenic high-alpine trail ride off our backside. The 3.3-mile, black-diamond Lenawee Trail descends one ridgeline east of A-Basin’s Montezuma Bowl, ending at County Road 260/Peru Creek Road.

Climb our Argentine North Fork Trail to the Upper Summer Road. The trail to access Lenawee heads east from the summit (to the left of the Lenawee Lift). When you finish your wild ride to the bottom, connect to additional trails and dirt road riding, if so desired. Please note Lenawee Trail is outside of our summer operating boundary, meaning mountain patrol services are not available. Be prepared and ride safe!

Lenawee is steep; it’s technical and it requires a shuttle or a big loop with significant time spent pedaling on roads. Arrange your shuttle to come back up to A-Basin to enjoy a cold beverage on the deck of the 6th Alley Bar & Grill.

Road Biking Near A-Basin

Loveland Pass Road

Arapahoe Basin is located just below scenic Loveland Pass. The category 1 climb up to the pass is a must-do for 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!
