Saint Lawrence River is one of the borders between USA and Canada. The river lies between northern Newyork and Ontario. The huge river houses nearly 1000 small islands. Rich people have bought these islands and built castles in them.
St.Lawrence River is a nice place to visit. They take you in a ship around the river and you can visit the castles and peep at St.Lawrence statue in the Canada border. The 150 mins trip in the ship costs 18$ per person.
