Welcome to this forum and to the RV lifestyle. We used to live in the west island of Montreal which was where we really started camping. We met a nice group at Camping Daoust in Hudson, and developed many long time friendships. We are still very active in this group here in Ontario but remember some of the great places we camped durin our years in Montreal.
We really enjoyed High Falls Park in Chateauguay, New York, and we actually spent a night there last fall and it is still very nice. The walk to the Falls is outstanding. We also enjoyed the Massena International Campground as it too was an easy drive from Montreal. There are still two chapters active in that area and one is made up almost completely of retirees who love to enjoy the less crowded times at campgrounds. Many of them actually now live just across the border in Ontario.
