This lovely lake sits just off Roche Harbor Road. As you pedal by, you might also spot a series of yurts on the peninsula that extends into the lake, giving it its name. This is Lakedale Resort, where you can book a stay in one of the yurts if you so desire.

This lake is the most popular one in Moran State Park. It's an ideal spot for a picnic by the water or for engaging in your favorite water activities. Additionally, there's a small shack that serves snacks, drinks, and even ice cream if you need to cool down from your ride.

At an elevation of 2,399 feet, Mount Constitution is the high point and pinnacle of Moran State Park. You have your choice of road or trail for climbing up to the summit, and you're rewarded with awesome views of Summit Lake, Twin Lake, and the bay.

Mountain Lake OSU is in a fantastic location and is not very busy. The circular route is very beautiful and pleasant to walk through the forest, even in warm summers. Of course, losing weight is also possible. Best at the height of. Parking spot.
