I most enjoy riding in quiet locations away from people. A couple years ago I discovered the Chimney Rock Road area on the other side of Utah Lake. There are miles and miles of dirt roads out there through beautiful, though sometimes rather harsh and desolate landscape. I have ridden out there quite a few times and have always enjoyed it. Conditions are best in the Spring and Fall. Summer is too hot and exposed. See this post:
In early Autumn I took my cyclocross bike and explored some new roads. I parked just past Chimney Rock, and instead of heading up Holmansville Pass Road, which I have ridden pretty regularly, I headed out across Cedar Valley on 12 Mile Pass Road for a few miles, then turned around and headed North on a track that got pretty rough in places. I then cut back East across very dry, powdery dirt tracks to the very straight road that goes to Fairfield. It was a nice exploratory ride, though at times I was wishing I had fatter tires.
