Commonly referred to as the "Cow Trails," the Highland Glen Nature Preserve has a network of single track and double track trails that are open to biking, running, and hiking. In the winter, this is a cross country ski area. The trails get their nickname from the herd of cows that lives in the preserve. Make sure to always close and latch any gates that you go through!

As you ride by on Manley Road, you get an epic view of Baldy across the water. The lake is surrounded by a host of unpaved trails within the Rotary Park, which are decent for gravel riding.
