Basically perfect ... super well maintained, flowy, a few basic features (good for a advanced beginner like me). Cool breezes, plenty of shade. Sandy parts can be tricky but they are few and fairly short. Some rooty sections, a bit of elevation change here and there. It's biggest flaw is that it's fairly small. I ride a 4 mile loop, reverse it, then repeat a couple of times. Works for me.
Have to say now that COVID restrictions have eased, the crowds (walkers, runners, many with dogs) have lessened. This reserve never closed and it has been busy over the past couple of months, especially on the trail that circles the lake. The trails that go deeper into the reserve are the highlight of the place, IMHO.
