On May 18, 2019, The Groveland Trails 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 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!

*18 miles of the original long route has been impacted by a Forest Closure Order due to the Ferguson Fire last year. We have worked with the Forest Service on a reroute of the closed section. The reroute is awesome! This new section added takes you to Pilot Peak Spring then past Pilot Peak, then down into Big Creek Basin and then climb out! We’re super excited about this new section we added! We apologize for the timing of this, it was out of our control but not a bad thing 😉 The red lined Forest Service road and Private Property road through Hazel Green Ranch may not be ridden before the day of the event. With the new section the long route is 41 miles with approximately 5,000 ft of climbing. Until we get more details for elevation gained on the new long route section we added you may use the medium route information for at least 30 miles of the long route

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

“Super ride yesterday! Loved having the Gatorades at the 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!”

“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.”

“Thanks for putting on a great event. I’d definitely do it again next year.”
