This is a great set of trails for everyone from beginners to veterans. It isn't the most technical trail out there, but it is well-maintained and has a great variety. There is one big loop "main street" from which most of the other trails can be accessed. These trails are all loops of various shapes and sizes off and includes some great climbs, some good technical rocky sections, some good downhills and much more. Mowed and great after a good rain shower. I personally recommend bb loop and powerline.
How to get there:
Take exit I-40 at Russellville exit 81. Then take highway 7 south all the way through town (around 5 miles). After going about 4 miles begin looking for a Honda shop on your left and a Kroger on your right. Turn right at the next light (Lock & Dam road). Drive all the way down Lock and Dam road until you arrive into the park.
Car parking at the first pavillion on the right (across the street from the tennis courts). There is a map posted of all the trails
