Great place to kayak! Try a twilight/sunrise trip. Gorgeous. Says John Pilla
A day on the slopes of Mount Sunapee is just what you need, and you'll meet a lot of folks from Harrisville here. The Route 9 and 123 to Hillsboro Fire Station sector is a splendid 6-mile-long class V segment of whitewater on Contoocook River - North Branch. This segment of Contoocook River - North Branch is well suited for whitewater paddlers who have been whitewater kayaking
or rafting for a period of time. The East Sullivan to Otterbrook Park portion has a span of 3.2 miles; you come across this bit of whitewater on Otter Brook.
