If you love boating you can do that here too. There is a boat launch in the park.
We personally would love to do some canoeing into the marshes. Owners of larger boats find a boat launch and docking facilities.
Long Point is attracts in addition many bird watchers because it is an migration stop for birds and waterfowl. Elizabeth, my wife, wants to come back in September when the beautiful Monarch butterflies have here a stop over on their way to Mexico. I still have problems to understand how a delicate insect can make such a long trip and how they find their way.

The village of Long Point as well as the park can be reached by a narrow road which is surrounded by protected wet land.
Above picture was taken during our first visit in winter.
Despite the ice cold and windy weather we liked it here. There were almost no activities but the park is still a major attraction.
To stay here in a well equipped trailer or motor home is certainly a special kind of adventure. In Europe such vacations are pretty popular!
But I am afraid you cannot stay here in that season despite all the wrong statements of our tourism "experts" who declared Ontario as a year long destination for visitors. To find excuses for doing nothing is easier than to find solutions! We had so many European visitors who returned disappointed that almost everything was closed.
