It services the Grand Lake, which is located in the Rocky Mountains and is Colorado's largest natural lake. The lake allows for a variety of watercraft, including motorized boats, sailboats, kayaks, and canoes. However, there are certain restrictions in place, such as a speed limit of 25 mph and a ban on personal watercraft. It is important to note that regulations and restrictions may change, so it is always recommended to check with local authorities before using the boat ramp and the lake.
