A convenient 10-15 minute ride or short drive from nearly all of the city’s surrounding neighborhoods, Camel’s Back Park is a gateway into the Ridge to Rivers trail system. With hundreds of miles of trail in 80,000 acres of land, this Boise Foothills trail system is a crown jewel of the city. 

What Makes It Great

On a warm spring evening, riding the Red Cliffs to Lower Hulls Gulch Loop is an unbeatably fun end of the day. From the south end of Camel’s Back, pick up the trail behind the tennis courts. This is a major entry point into the Reserve so be prepared to share the trail. Under wonderful shade of tall, rustling trees (also the home to resident owls) ride Gold Finch to Owl’s Roost Trails, which offer a good warm-up. 

The turn up steep Red Cliffs Trail gets quads burning and while no game ender, this first climb requires commitment – or a quick shift into granny gear. The dramatic panorama views of the vast green valley below bisected by the Boise River and edged by the Owyhee Mountains dominates the steady, moderate climb up to Crestline Trail.

After an exhilarating descent to a bridge at the top of Lower Hulls Gulch, the ride switches from rolling sand-dirt to more technical, creek-side terrain. There are two gigantic trail-hogging boulder features along the way that all but the most advanced rider will want to walk– you cannot miss these. Winding along a gurgling seasonal creek, this portion of the trail can be ridden fast with sharp skill, or taken slow while brushing off winter’s cobwebs.  

Insider tip: In spring and early summer when temps hit sweat-inducing highs, the creek crossing at the Lower Hulls Gulch / Crestline junction offers a great opportunity for head dunking.

Who is Going to Love It

This route has some technical sections and can be tricky to maneuver. It's recommended for intermediate to advanced riders.

Directions, Parking, & Regulations

Remember trail etiquette: Bikers yield to all others. Downhill riders yield to uphill. Be a trail steward – don’t ride when trails are muddy and vulnerable to a trashing by tires. The trail is also rideable in winter for hearty souls who don't mind bitter temps and occasional snow.
