A classic Stack Rock ride up in the trees above Boise.

Chris Wandervans


Snowbound until mid-May.


The Eastside Trail is the main trunk trail in the Stack Rock trail system. It can be combined with many other trails to form a great all-day ride. The first part of the trail was constructed in 2003 and 2004 on mostly old logging roads from the 50s and 60s by mountain bikers. The trail is fast and swoopy and has a number of stream crossings and technical features. Technical features have been added along the sides of the trail for years to provide some alternatives for more experienced riders.

The main trail is an intermediate trail and can be used to avoid any technical features along the sides of the trail. Technical features are all difficult and some involve log rides or picking your way through tight rock sections.

The best place to start the trail is from Bogus Basin road. After leaving the road you'll drop onto the XC ski trails for a little ways. You'll just need to make sure to stay left at any junction, but everything is signed well. Once off the XC ski trails, the trail will continue descending down the mountain. At a viewpoint a trail drops in from the left and then shortly afterwards sinker creek trail peels off on the right, follow the signs and stay on Eastside. The next junction will be a sharp turn at the DB connector. Turn left and continue down the trail all the way to the creek bottom at Sinker Creek. At this junction follow the signs across the creek and begin climbing out of the drainage. The Eastside trail then terminates at the Stack Rock Trail.

You can park at the pullouts along the road or at the ski resort and then use the Stack Rock Trail to return to the road at the end of the trail. This trail is also used to connect to Sweet Connie or to access Stack Rock. There are no bail out points that take you back to the road until the end of the trail, so please be prepared.

I recommend this ride. Especially combining it with Jacobs(?) Stack Rock Trail. For an 18-mile lollypop ride.

Did this ride in conjunction with the loop part of Stack Rock Trail. Very Fun. The trail stays in the trees the whole time.

Getting dry. Avoid the outer edges of the trail, they are soft ans sandy. You can see where others got sucked off the trail.
