Originally used as a fire tower near Isle, Minnesota, this 100-foot tower was relocated to the park in 1981. It is situated on one of the highest hills of the Mille Lacs Moraine, a glacial ridge that acts as a natural dam for Mille Lacs Lake. If you climb the staircase to the top, you will be rewarded with spectacular views! Just keep in mind that you'll need to climb 133 steps to reach the summit.
