As it emerges from Lake Ontario, for an 80km stretch the St Lawrence River is dotted with a thousand and more islands of varying sizes. Between Canada and the United States, this archipelago, with glistening waters lapping at forested shores, is a popular holiday area, dedicated to water sports. While large ships pass along the river's American bank, a host of recreational boats, yachts and dinghies criss-cross between the islands, affording a peek into the summer residences hidden in the trees... A cruise is a must!
