Blue Trail: I believe this is the most difficult trail in the Enterprise South trail system. It's not long, and has a good mixture of climbs and descents. Nothing too long on either. There is a bit of gravel, so keep an eye on the inside of corners.
Trial directions change depending on the day you go, so be careful and read the signs. There is ample amounts of parking around the park.
Overall, it's a nice system of trails. Great for beginners.
