Overview

Single Track Biking is growing in the nation and Girdwood is rapidly making its mark. Alyeska Bike Park is routinely in the top 10 list for resorts with downhill mountain biking. The Girdwood Mountain Bike Alliance (GMBA), recognizing a need for non-lift access single tracks, started the daunting venture of building a park. Every year they add to the park with the expectation of multiple trails in the future.

Getting There

The Girdwood Mountain Bike Park (GMBP) is 45 minutes from Anchorage and right next to Alyeska Resort. The GMBP Single Tracks are accessed via the 5K Nordic ski loop. The beginning of the bike trails is on the back part of the 5K loop which is about 1-1.5 miles up the nordic loop. There is a paved parking lot at the end of Arlberg Road.  

The Trails

Currently, there are three main trails on the system totaling about 2 miles. The trails contain features like banked turns, rolling terrain, various types of jumps with consistent and predictable surfaces. This location was chosen because of the rolling terrain and the perfect amount of gradient. It’s not too steep, yet provides features for fun mountain biking.   

Small House is the easiest trail system and provides an easy gradient to give you speed with nice banking opportunities. As you bike up the 5K loop, take the road to the left and look for the single track sign for Small House. It will be on your left about a mile up the 5K loop. In 2020, they were adding on to Small House with an extension. 

Two cents and Earnagain are connected and both are quite steep. Two cents is the trail that heads uphill with switchbacks in some places. Once you get to the top, the trail changes to Earnagain. The downhill is fun but riders should expect some steep banks and jumps that drop 2-3 feet. To access this trail, stay to the left of the road after entering the 5K loops and take it all the way to the top...about 1.5 miles. It’s past Small House. All trails are also listed on Trailfoks.

Winter Considerations

This trail is ONLY opened for bike riders in the fall, last spring, and summer. Once it snows and the 5K Nordic Loop is groomed for winter use, they close it to bikers and walkers.
