Round Valley Reservoir is a perfect place to paddle with its vast beauty and deep blue waters. It’s located in Clinton Township, New Jersey by Route 78, also not far from Spruce Run Reservoir. It’s a very large and active lake, you’ll see sailboats, canoes, kayaks, paddle-boarders, fishermen, people swimming and hiking. Paddling near the middle of the lake was a bit choppy, staying along the coastline was more enjoyable for us.
