Ennis Lake was formed when a dam was built on the Madison River at the head of the Bear Trap Canyon. The lake is shallow meaning the water is warm, just right for morning water sports and windsurfing in the windy afternoon. Ice skating and ice fishing is an option in the winter; due to the shallow water, the lake freezes easily.
From the town of Ennis, travel north along US highway 287, approximately 6.5 miles. At the McAllister Junction, turn right onto Ennis Lake Road and travel another three miles.
