Need to Know

Parking is off of Hess Road, 1.5 miles north of Grange Hall Rd (Exit 101 off of I-75)

The trails are a mix of clay, sand and dirt. Please do not ride after rainfall.


Part of the Holly Recreation Area, the trail system consists of three main loops, North Loop, West Loop, and East Loop aka "Gruber's Grinder."

The Holdridge Trail system's flagship feature is the East Loop aka "Gruber's Grinder", a 15.5-mile advanced trail, Gruber's Grinder. It is very technical, much like Highland Recreation Area's mountain bike trails, and should be ridden by newcomers with caution.

The West Loop and North Loop are more accessible yet still quite fun, and the tech loop contains skinnies, drops, and rock and log piles for those who enjoy riding technical features. The Lake Loop adds an addition mile to the West Loop and consists of some tighter singletrack and many wooden boardwalks. While they are low/inset into the ground, riders should use caution as they are extremely slippery when wet!

Designed and maintained by the Michigan Mountain Biking Association CRAMBA Chapter, these trails are some of the best in southeastern Michigan. 25 miles of trail is broken into various loops that accommodate all age and skill level of riders, from beginner to expert. There are many lakes, ponds and swamp areas along all of the trails here. It's advised to wear bug spray in the summer months.

At the parking lot there is a small picnic shelter and grill, along with a hand pump that delivers great fresh water so you can come out and make a day of it!

Plenty of turtles can be seen sunning themselves on logs on sunny days!

History & Background

This trail system began its life as equestrian trails. When they had been all but abandoned, the Michigan Mountain Biking Association worked with the State on a trial basis to open it up to mountain biking. The rest is history!
