Sections of the trail is open to dual sport motorcycles seasonally, know the dates and plan accordingly.
A great way to try out rocky ridge riding, Middle Ridge is easy to get to and easy to bail from if you are in over your head. The trail is best ridden from East to West and seems to get slightly easier in that direction as well. The beginning is a jumble of rocks that its difficult to stay on top of, but remember that momentum is your friend.
The trail intersects with several trails that traverse between Hunter Rd and Henstep Valley Trail, so there are always options to shorten your ride. The intersections themselves aren't always marked, but its pretty clear that you want to stay on the ridge and keep following the trail on the spine itself.
There are a few rock outcroppings with cool technical lines thrown in, definitely take the time to play on these features. At the end, the trail drops off pretty steeply, including several water bars, so be careful and pick your line wisely.
