----------What we do---------

Trails Initiatives

Our community service initiatives have led to the creation of many miles of trails across the reservation and we serve in an oversight capacity, promoting the developments of trails across the Nation. Our summer trails crews focus on trails in the tribal parks, with an ongoing efforts at LCR, 4Corners, Asaayi, Rainbow Trail and Window Rock.

Youth Programs

We began offering outdoor adventures for youth in the Shonto community in 1988. Since that time, we have been involved in offering positive programs and activities for youth and communities across the Navajo Nation.

Diné Bike Project

We began offering outdoor adventures for youth in the Shonto community in 1988. Since that time, we have been involved in offering positive programs and activities for youth and communities across the Navajo Nation, with over 300 outings at Navajo Mountain, Chuskas, LCR, Grand Canyon, Carrizo Mountains and Rainbow Bridge.

Navajo Parks Race Series

The Navajo Parks Race Series was initiated in 2015 as a partnership of NavajoYES with Navajo Parks & Rec and the Office of Navajo President & Vice President. The intent of the Series is to promote health and wellness, while exposing folks to the beauty of Dine’ Bikeyah. The 2018 Series will feature events at Navajo Mountain/Rainbow Bridge, Monument Valley, Little Colorado River Gorge, Window Rock, Shiprock, Camp Asaayi and Four Corners.

Education and Outreach

We love to visit schools and communities to share the message of health and wellness. We also have created a series of posters, trail guides and other resources to promote healthy living in Dine' Bikeyah. Whether it be a health fair, school presentation, chapter meeting, or other event, we'll be glad to be there.
