January 30, 2025, Lafayette Reservoir Recreation Area

There are a bunch of great hiking and biking trails around the reservoir. Some, like the Shore Trail, are two-lane paved cycleways with no vehicle traffic, and others are unpaved dirt roads up in the hills. All are beautiful trails to explore on two wheels!
