Sail and power boats use one side but rarely venture to the other because of a low bridge and rocks that have a habit of popping up just about anywhere. Swimming and wading is not permitted but there are some very nice beaches where you can fish or have a nice lunch.
Loons are a very common site here.
As you all know it's a huge lake where you can swim, fish, basically anything you want. There are a lot of boats to avoid, many traveling a lot faster than they should on a lake. We took a trip last year from Center Harbor to the Burger King in Paugus bay, roughly 14 miles with shore line and islands the whole way. Best done at the end of the season or during the week when most people aren't out in power boats. A beautiful lake with a tremendous amount of ski-doos and power boats.
