Good mountain biking trail. Unpaved and well maintained single-width path through the woods. Watch for roots, branches and other hazards. Traffic is in both directions. Lots of good elevation changes and challenges such as creek crossings without bridges. Loop entrance map claims that it's a 9-mile loop but different GPS units show between 9.5 and 10 miles. Trail is adequately marked but there are a few spots that aren't immediately clear.
Great hike. Will come back to run it next week. Not hard. Length is the only thing that makes it Moderate.
Either I got lost, or this trail is 10.5, not 9.5. I based my morning off of one less mile and was not happy about missing a work meeting.
As a hiker, I had a poor experience. I was continuously stepping aside as best I could to avoid large groups of mountain bikers. Trail was not clear and we managed to circle back to the start of the train twice, never getting to do the whole loop.
Did all 9 hiking today. Exhausting! Didn't even see a bug! But I like that. Probably beautiful as leaves change.
