    Table of contents

    North Boulder Valley is a fun cross-country trail perfect for ripping around on your gravel grinder or cross bike. We love it because it is pretty much accessible year-round, with few trees and lots of sun exposure it dries out fast and its quick to get to if you don’t have a lot of time!

    Route Description for North Boulder Valley

    North Boulder Valley is a combination of single track and gravel trails that are perfect for ripping around on your gravel grinder or cross bike. If the flat gravel track isn’t enough for you, there is always a single-track trail next to the gravel path.

    From the Eagle Trailhead, you will start on a flat gravel trail, Eagle Trail, towards Boulder Valley. At a junction, drop down onto Sage Trail to loop around Boulder Valley. Sage Trail will eventually meet back up with Eagle Trail at the Boulder Valley Ranch Trailhead parking.

    From here, you will want to hop on Left Hand Trail which is a great out-and-back single-track trail that cruises around Left Hand Valley Reservoir. Left Hand Trail will dead-end into a parking lot on Neva Rd. Turn around and retrace your tracks back to Eagle Trail.

    Complete the loop around Boulder Valley by taking the section of Eagle Trail you skipped when you hopped on Sage Trail, returning to the trail junction for both. Make your way back to Eagle Trailhead as you blast back down the flat gravel trail.
