Ridge to Rivers Trail System

The Boise Foothills rise above Idaho's Capitol and largest city, providing a postcard backdrop that inspires and soothes the soul. An interconnected network of roads and trails courses through these hills, linking not only neighborhoods with public lands but also connecting people with the natural environment. With over 130 miles of trail, there is something for everyone. Here we provide ideas and tips about where to go, how to enjoy the Foothills without hurting them, and information about the area you may find interesting. As you explore, notice the diversity in the land, the plants and the animals, then imagine our community without this unique treasure. You can help protect and care for this special place by learning more about the land and its needs.

The Ridge to Rivers Trail System provides a variety of experiences and opportunities. Some trails are steep and require skill or stamina to negotiate, while others are more gradual and suitable for a wide range of abilities. The Hulls Gulch National Recreation Trail is part of this system.

This trail system is multi-agency partnership consisting of the City of Boise, the BLM Four Rivers Field Office, Ada County Parks and Waterways, the Boise National Forest and the Idaho Department of Fish and Game. Existing Ridge to Rivers pathways cross all of these jurisdictions, as well as many private lands via revocable or permanent easements.

Trail Etiquette

  • Be Courteous - Mountain bikers, please slow down for others, including other riders. 
  • Control your pets to avoid scaring people and wildlife. 
  • Share the trails. 
  • Respect private land by staying only on the marked trails. 
  • Be Careful - Rattlesnakes, ticks, poison ivy, heat, steep drop offs and rough trails are part of the trail experience. Use caution and be prepared.
  • Because many of the trails cross private land, it is important to stay on the marked trails. Landowners have been kind to allow public access on select trails so we must repay the generosity by respecting their land. Travel off marked trails is trespassing and puts at risk the future of public access on private land.

Purchase a map from the BLM at the Idaho State Office located at 1387 South Vinnell Way in Boise, Idaho. Maps can also be purchased from other vendors.

In the Spotlight

Are you interested in how these trails will be managed in the future? We want to hear from you! The Ridge to Rivers partnership is initiating a master planning process that will guide development and management of the popular trail system over the next 10 years. The planning process will take place over the next year. It will include an initial on-line trail user survey from October 1st through 15th, followed by two rounds of public open house workshops and additional on-line opportunities to provide input. The goal is to put together a plan that meets the needs of our trail users while balancing wildlife habitat, clean water and natural resources management. Learn more.
