Ensure you pay the Kiosk for parking. I wasn't able to complete all the trails. However, from what I was able to ride today, was very smooth. In most spots the flow was fast. I enjoyed it. I'm definitely coming back for more this weekend.
The green trail by the creek is a beautiful hike. It's about 5 miles if you start at the park and loop all the way around the nature center. There are a lot of older trail markings of different colors painted on the trees and a couple of unmarked splits, so it's easy to get confused. The metal diamonds nailed to the trees are the more current markings.
My only complaint is the bathroom. I can never unsee what I walked into. The nastiest gas stations have cleaner bathrooms. Other than that, the trails are easy to navigate and falls are nice. although care should be taken, watched a lady bust her ass while taking a photo.
This is one of my favorite parks to go to without traveling over an hour to get to a decent but secluded park. I recommend coming on weekdays oppose to weekends due to it being crowded on weekends. There's 2-3 man-made waterfalls from old mills and one natural waterfall that's roughly a 4 mile hike on the opposing end of the main park! Enjoy!
