Barnston Island sits in the Fraser River along the Surrey section of the river. Barnston's a small island, (only about 2-3 square miles) and you get to it by taking a 5 minute ferry ride across Parson's Channel to the island. The ferry ride is free. Actually, it's not much of a ferry but rather a tug with a small barge tied along side of it. The ferry ride makes this activity a bit of an adventure for small children. Barnston Island is flat with not much on there but farms. A road circumvents the island, and takes about an hour by bike.
