Trail Tending Outings

Give back to the lands that nourish your spirit. Trail day events are much more than moving dirt and boulders; spend time with friends enjoying backcountry scenic views, wildlife and wildflowers, while creating a space for others to do the same. Review the list of events below and RSVP soon and often!

Recreation Trips

Discover new places and make new friends while recreating on local Mariposa trails. The Mariposa front-country is an awesome place to hike, bike, run or to simply saunter while enjoying the local wildlife, plants and beautiful scenery. Be a participant, lead a trip on one of your favorite trails, or manage this program.

Race Events

Trail racing, whether on bike or foot, can be a fun way to experience the front-country of Mariposa County. Be a participant, a race event volunteer, or help manage this program. Volunteering on race day is a great way to build friendships and community while earning race apparel and free food and beverages!

Youth Pathways

MARIPOSA TRAILS embraces youth participation in our programs. This has taken many forms in the past; over time, this is anticipated to expand. To date, MARIPOSA TRAILS have programmed multiday backpacking trail-tending outings with colleges throughout the state; partnered with the US Forest Service for local students to develop cultural interpretation products for use on local trails; and, engaged Mariposa County High School students to manufacture trail wayfinding signs to be placed in recently burned forests.

We are currently looking for a volunteer to fill and expand this role.

I’d like to fill this role.
