Mill Creek
The entire Empire 4X4 Loop provides a full "Colorado" experience, but Mill Creek takes it to the next level. This trail includes a well-preserved historic cabin, mining ruins, stream crossings, snow-patched mountains, aspen trees, rocks to crawl over, and wildflowers. This off-road trail has something for everyone and should not be missed. It sits about 1 hour from Denver, Colorado, and is within the Arapahoe National Forest. You can combine this trail with other trails in the area for a full day of off-road fun that is just challenging enough to keep the wheeling interesting while soaking in the amazing views of the Colorado Rocky Mountains.
