Alum Creek's 3,387-acre reservoir and 4,630-acres of gently rolling span of fields and woodlands provides a hub of recreational activity just minutes from Ohio's capital city. Quiet coves nestled among shale cliffs await the solitary fisherman in the park's northern reaches while sunseekers mingle with thousands on Ohio's largest inland beach.
From the pics/map and dozens of times I've been there this looks like its the Alum Creek Phase 2 mountain bike trail. If so: this trail is amazing. COMBO does a great job with upkeep and it's both more smooth and more challenging than phase 1 (slightly less rooty/slightly more challenging obstacles and hills). I think it's actually about 6 miles total. Great place to ride!
While this is a Mountain Bike trail, it is also a great hiking trail. It has been well prepared for bikes for the ground is hard in most places and bridges for every gully. It has built to follow the water line of Alum Creek Lake and does so by often backtracking itself. The Nature is beautiful and on the whole six mile trip, I only had to move off trail to let 4 bikes pass. All in all a great hiking trail. Go counter clockwise to have the bikes coming at you or Clockwise to have them coming from behind. Hiking Time BTW is about 1.75 hours.
I have only ridden Phase 1 a few times. I don't think its a good trail, mainly because some of the roots can stop you and your bike dead. I had to abandon one run because of a fall and large cut on my knee. Phase 2 seems easier to me. It is called a technical run, but I think of it as more of a fun free-style. Prob one of the better runs in Ohio I've been on.

Awesome trail, has everything you could want. Hills, wood bridges, lots of them, roots, log jumps. First time on this trail, I'll be here for 3 days, gonna ride it everyday I'm here.
I didn't quite hike this trail; I actually left the trail because it was very boring in my opinion. I spent my hike walking along the shores of the lake. I really liked doing so; the lake was pretty and fairly clean and the shoreline wasn't dirty either.
Same as what Ron said, there are 2 trails. Phase 1 and Phase 2. I hit phase 2 the most " about 2 times a week" phase 1 is kinda boring after riding phase 2 hard. Phase 1 is still nice to hit when my girlfriend wants to come and ride with us. Challenging for her , but nothing to really get her into trouble... Like some of the bridges in phase 2
