About The Groveland
Trail Heads 

Creating, enhancing and preserving exceptional trail experiences for all trail users.

The GROVELAND TRAIL HEADS mountain bicycling club, established in January, 2013 is an educational association, non-profit 501c(3) Chapter of the International Mountain Bicycling Association(IMBA).

We partner with the Stanislaus National Forest’s Groveland Ranger District to develop and mange the Ferretti Non Motorized Trail System (Ferretti Trails) as public use, mountain bike specific trail system. 

We also host our annual signature event under a Special Use Permit with Stanislaus National Forest.  The Groveland Grind is a Yosemite Area Adventure Ride on mixed terrain (pavement, broken pavement, dirt, ruts and gravel) on Yosemite National Park’s doorstep.

Why It Matters

Trails transform communities. They offer spaces for physical activity, mental rejuvenation, and connection with nature. In rural areas like Groveland, trails provide vital recreational opportunities, boost tourism, reduce wildfire danger and serve as a buffer for local businesses during park closures or other disruptions. By promoting responsible trail use and stewardship, we’re ensuring these benefits endure for generations.

Our Impact 

Environmental Stewardship

Removing dangerous fuels and creating sustainable trails helps prevent wildfires and protects our watersheds. Sustainable trail practices also reduce erosion and safeguard the delicate ecosystems that make our area unique.

Youth Empowerment

Teaching forest stewardship and conservation skills equips the next generation to care for our natural resources. Our programs inspire confidence and curiosity in young people while fostering a love for the outdoors.

Cultural Connection

Highlighting the historic and cultural significance of our lands fosters a deeper appreciation for the region’s heritage.

Health and Well-being

Trails encourage physical activity, reduce stress, and provide opportunities for social interaction. They create a space for individuals and families to enjoy outdoor recreation, promoting both mental and physical health.

Economic Resilience

By offering year-round recreation opportunities, our trails help stabilize the local economy. During periods when Yosemite National Park is inaccessible, our trails draw visitors to the region, supporting local businesses and tourism.
