Thing to Do
Alley Slough Trail

0.3 mile loop. This easy hike begins at the historic Alley Mill located on the banks of Alley Spring. Following a tour of the old turbine powered grist mill, visitors can walk the perimeter of the deep blue spring along a trail that hugs the base of a massive dolomite cliff. The remnants of the old stone impoundment and mill sluice send the 81 million gallons of water per day that flow from Alley Spring cascading into the spring branch. The trail continues for a short distance along the spring branch past a series of small caves and moss-covered rock outcroppings and continues down the branch to the visitor parking area.
