The helmet cam takes us to northern Oakland County to Holly Recreation Area, specifically Holdridge Lakes mountain bike trails, about 4 miles west of the main park.
Close to 30 miles of trail, it offers something for all types of riders. Short loops north and west with the east loop, Gruber's Grinder, 15 miles and the marquee loop of the network. The first four miles of Gruber's aren't heart attack hills but there are many (many) of them. Once you get past those though, the flow levels out a bit and is a fun, twisty trail.
trailhead
As noted above, the trailhead is not in the main portion of the park; it resides off of Hess Rd which runs off of Grange Hall Rd, east of the town of Holly. The sign for the road/trailhead off of Grange Hall always seems to be blocked by some shrubs so best to have the idiot phone warn you when you are close.
positives
Again, a trail for all riders. Even Gruber's, while a bear, has two exit points at miles 7 and 9 if the mojo is not there.
negatives
No trail negatives but Hess Rd scares the hell out of me as it is one narrow dirt road with trees hovering over it. A dead end to boot, I'm waiting for either a tree to fall onto my vehicle while coming down the road or getting stuck at the trailhead because of a tree blocking the road.
Attached is a mix from Gruber's with yet another fall from yours truly at about the 40 second mark. A lesson learned in respecting the caution signs and not trying to start pedaling in the middle of a large downhill.
