“A really nice trail through some beautiful country with nothing but the cows to keep you company.”— Phil H

The trail is well marked with diamond signage, and Forest Service signage posts. The Centennial Trail symbol is a cow skull with horns. If you take this route as mapped, you'll start at a closed road with a metal gate, just off of Sheridan Lake Road. The trail starts right there and there is room for three maybe four cars.
There is some sustained climbing from the start, but I did not find it terribly strenuous. This area has free range cattle running around. They don't get many visitors and the cattle seemed very confused and scared. Sorry moo's.
As it continues, the trail connects the dots between a few abandoned doubletrack roads. It's important to pay attention to the Forest Service placards because they route you off of one road to another many times. You may also want to keep the MTB Project mobile app handy to avoid having to double back.
The trail mixes from singletrack to doubletrack and when you come to the power lines the trail goes right off of the road you have been riding on. Continue climbing then come to a meadow with some downhill. The trail diverts you off of this road with signage and some downed logs crossing the road.
Eventually, the doubletrack climbs up to a stunning vista of grassland in the middle of this forested area. The next downhill is a treat as the singletrack snakes through the grasslands. The trail turns right, and climbs. Keep an eye peeled for the cairns (stone piles) as the trail was completely gone here.
After this climb riders will reach the best part of the trail. The descent is fast, flowy, and giggle inducing. You cross a stream and then the trail goes up through some areas that are newly planted. After climbing for a while, you come to another downhill section. Pay attention because there are some sharp 90-degree turns in this section.
Finally you'll end up on a well-used road that makes for a good exit. We went to YMCA Road and then rode out to the highway.
