Pinnacle has some awesome views and if you choose a good trail its a pretty sweet ride. Following Kellys run does involve a lot of picking up your bike and carrying it over rocks. Im not talking small stuff here. There are a number of small cliff things that hikers have to scale.
The fire road starts off as a fire road and quickly thickens up with brush. Watch out for spider webs! At the bottom there is a brige thats out and you have to cross the stream to the other side.
There are a number of trails here, a number of which are rideable. There are a couple for hiking only and several horse trails to follow.
One note tho, the map is the worst. Its little more than a doodling. (you can find it if you google Kellys run Pinnacle trail. Its the one thats pplweb) I have yet to figure out exactly where I am at any given time. A number of trails cross others that just arent on the map, and the trail marking system is sad to say the least. Sometimes youre lucky if you can find a trail mark. There are also 2 red trails and 2 yellow trails!
Other than that, its pretty nice.
