Welcome to the Shafer Butte Trail System

Boise residents and visitors are now able to mountain bike from the top of Bogus Basin all the way to the Boise foothills and eventually to the new Eagle Velodrome and Cycling Park on the new Shafer Butte trail system. 

The National Park Service, through its Rivers, Trails and Conservation Assistance program (RTCA) responded to a request for assistance from Southwest Idaho Mountain Bike Association (SWIMBA) to develop a plan and guide for a proposed trail system in and around Bogus BasinA number of critical partners including the Boise National Forest, Ridge to Rivers Partnership, Bogus Basin Mountain Recreation Area and SWIMBA, planned and implemented a trail system that complements and connects to the existing Ridge to Rivers Trails in Boise.

Food service is available on weekends 11:00am - 4:00pm at the JR Simplot lodge. Directions here >>>



Open mid-June (when snow melts and trails aren't muddy) through mid-October

No trail fees required. These are not chairlift-served mountain bike trails. There are limited resources such as water and food. Restrooms are available in the parking lot near the tubing hill. The lodges (Pioneer, Simplot, or Frontier Point) are not accessible. Please take all necessary precautions to have a safe, fun and adventurous outing.  Please pack-in/pack-out any garbage.

The Ridge to Rivers Trail System is a unique partnership among government agencies, private landowners, organizations and individuals.  Its exceptional roads and trails meander through approximately 80,000 acres of land between the Boise Ridge and the Boise River. These roads and trails link more than land and water...they connect people with each other and the environment.  Your care and courtesy will help protect these fragile foothills.
