Event description


On May 18, 2019, The Groveland Trail Heads in partnership with the Stanislaus National Forest, Yosemite Lakes RV Resort and Campground, and the Adventure Sports Journal present the 2019 Groveland Grind, a Yosemite area Adventure Ride! This is a multi terrain (pavement, broken pavement, gravel, small rocks and dirt) adventure ride that takes riders through some of the most beautiful and historic sections of the majestic Stanislaus National Forest. All three routes are truly special as they hug the border of Yosemite National Park! With some sections on the original road and railroad to Yosemite!

The town of Groveland is a short 2.5 hours away from the Bay Area and Sacramento, and offers an abundance of activities for both riders and non-riders alike.


The GROVELAND TRAIL HEADS mountain bicycling club, a non-profit educational association whose mission is to create, enhance and preserve great trail experiences has been partnering with the Stanislaus National Forest, Groveland Ranger District to develop a public use, mountain biking specific trail system in Groveland, CA. The proceeds from this event support this mission as the project has recently been approved and we are able to start the process of building mountain bike trails!

"Super ride yesterday! Loved having the Gatorades at the rest stops!!!! Plenty of rest stops! Planning on next year already. We went up the easterly route to 5 Corners and down the westerly, dirt road from 5 Corners. Really like that direction as the downhill on the dirt road is the best!!!!!! The view from Trumbell Lookout was beautiful. We have been meaning to get out there for years....thanks to you guys.....we finally dragged our butts out there :) Thank you for a wonderful day, and thank you for planning such perfect weather!"

"Epic ride! Beautiful scenery. Couldn’t get enough pictures!"

"The fun of the whole ride was the unknown! You explained everything perfectly. This type of riding took me out of my comfort zone and I am so glad I did it. Thank you for introducing me to a whole new type of riding."
