First things first, this is a horse trail so if that bothers you stay away. There are several trails to choose from at the trailhead for a total of about 40 miles in this area.
The Yellow and the Red Trail begin together and overlap for the first two miles of this 5.5-mile loop. The first two thirds of this trail are typical horse trail that not many bikers would like. However, after a few miles, things level out and the trail become enjoyable. There are a few good views along the trail, especially in the hilly section.
The trail is also very wide, think ATV trail, but it is considered singletrack. The trail is marked with red arrows but they can be difficult to locate at times. It is highly recommend you download the GPX file to your GPS or use the MTB Project mobile app
and just follow the track verses getting lost.
The official trailhead is at Warden Station and camping is allowed there. However, I would highly recommend the camping at Coleman Lake which has power, dump station, and bath houses. You can access the trail from Coleman Lake by riding across the dam on the loop trail around the lake then go immediately uphill to the left but the trail eventually swings to the right and into the Yellow Trail
which leads to the Red Trail.
Though this is a horse trail, you are likely to have the trail to yourself once you get away from the trailhead. Remember to yield the trail to equestrian users. If you only have time for one loop I would ride the Yellow Trail
before riding the Red; as of this posting, I have not ridden the Blue Trail which is 20 miles long.
Pros: Hilly if you like hills, wide, remote (no cell service), camping, scenic
Cons: Hilly if you don't like hills, horses, briers can lean into the trail, little traffic so leaves can cover the trail in the fall
As a side note, this area has some awesome gravel roads.
