Lake Whitehall is part of a state park in Hopkington. It is shallow but very clean and quiet. The views are spectacular with very few homes visible from the water. You feel like your paddling in a lake in northern reaches of New England. There are very few boats; mostly fishermen. The lake is full of inlets, and is a maze of neat islands to explore. There is a waterway in the middle of the lake you follow like a river with islands and marsh on 3 ft either side of you. The lake is full of wildlife. Its a great size lake for a kayak or canoe. It takes me about 1 hr to get to the other side from the launch in a kayak. But you can go all around it in about 4 hours.
There is plenty of paved parking and a great boat launch. No bathrooms. There is also a hiking trail that goes all around the lake that takes about 3hrs to do.
