Ennis Lake is relatively shallow and acts like a giant solar collector. The waters in the lake can heat up to 85º (the temperature of a very warm swimming pool) in the summertime making it a great place to swim. Kobayashi Beach is a favorite locals hangout. Its sandy beach is managed by the BLM for Montana Power Company. It’s easy to find and makes a great place to take a break from the traveling. At the tiny town of McAllister just north of Ennis, take the road heading east out of town for a little over 3 miles. After you pass through a housing area, you will see the signed beach.
