Plan on getting muddy in Loud Thunder State Park. There are several short trails consisting of single track. You must connect them to make the ride worth the effort. Even at 8 miles you could do the circuit of trails twice in under two hours. The ride is sort of technical due to how wet the trail is.
How to get there:
Take Hwy 67 into Andalusia. Then head west on Andalusia and follow it until you come to the entrance for Loud Thunder State Park. Enter and follow road to horse stables. Park here and trail should be visible.
