Groveland Grind 2024! Our 4th Groveland Grind on Saturday, June 8th!

The Ultimate Gravel/MTB Cycling Adventure Returns to Groveland, CA!

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! Three amazing routes with amazing views to choose from- Ride the 48 miles Long route- The Rumble up to Trumbull(Peak), the 30 miles medium route or the 21 miles Short route through the majestic Stanislaus National Forest on historic sections of the original roads and railroads to Yosemite! Groveland is just 2 to 3 hrs from San Jose/San Francisco/Santa Cruz/Sacramento and 1 to 2 hrs from the Central Valley.

The event takes place at Thousand Trails Yosemite Lakes, 31191 Hardin Flat Rd., Groveland, CA, 5 miles from the “Big Oak Flat” entrance to Yosemite National Park and next to the South Fork of the Tuolumne River! Camping is available for tents, vans, RV’s and trailers, please see ADDITIONAL INFO below.

The Groveland Grind supports the Groveland Trail Heads and their development of a mountain bike specific single-track trail system that is inclusive while promoting health(physical and mental), outdoor recreation, adventure and economic development throughout the Groveland area. We’re trying to raise $20K to help fund our next mountain bike trail in the Ferretti Trails trail system!


You must be in good physical condition for all routes.

Safety and fun go hand-in-hand, and there will be both aid stations, medical personnel, route marshals, communication and transportation if needed.

The Long and Medium routes go through beautiful Hazel Green Ranch(private property)which borders Yosemite.
