Canoe-Picnic Point State Park

Sugar Island is located in the Thousand Islands region of the St. Lawrence River in the United Counties of Leeds and Grenville, Ontario. It is roughly 35 acres (140,000 m2) of undeveloped island wilderness. In the 1950s the local nautical charts changed the name from St. Lawrence Island to the name the island has now, Sugar Island. In the late 19th century the island was inhabited the year round by a farming family, and the maple trees were tapped for syrup, which gave Sugar Island its current name. In 1900, the American Canoe Association formed a committee to obtain a permanent site on the St. Lawrence River to hold its annual meet. On July 18, 1901, Sugar Island, then known as St. Lawrence island, was purchased for $1,000 on land set aside for use of the Mississaguas of Alnwick Indians. Starting in 1903 they hosted the annual meet for camping, competition and camaraderie between canoeists. Canoeists, kayakers and sailors come to visit from around the world and participate in longstanding competitions. The national encampment has been held every year since 1903 with the exception of Turtle Island in Lake George in 1926, no meets in 1944 and 1945, and one National Encampment in the Midwest in the 1970s. Members and their guests traveled for many years by train to Clayton, New York, or Gananoque, Canada, and paddled or traveled by ferry to the island. The ferry "Yenneck" serviced the island for twenty-five years. For many years the only buildings on the island were the mess hall, the storehouse, and the ice house, the latter a favorite gathering place of the younger generation. After World War II a limited number of cabin sites were made available to members. There is still no electricity or phone service on the island.

Murray Isle is an island in the Thousand Islands region of the St. Lawrence River in the U.S. state of New York. The island lies in the Town of Clayton, near its border with the Town of Orleans, in the northern part of Jefferson County. Today, Murray Isle is the site of many summer cottages. While the record is unclear, it is believed that the first cottage on Murray Isle was built in 1860. The structure, a simple log cabin, was owned by Daniel Sherman. By 1880, the island had four cottages, all located upriver, on the northern portion of the island. Murray was formerly known as Hemlock Island due to the presence of that variety of tree, but the name was changed in the late 18th century to Murray Hill Park after the Murray Hill area of New York City when the island was developed and lots sold off. The development was never finished. The name was shortened to its present form some time later. The Murray Hill Hotel was built on the island in the late 19th century, and served tourists who came over on steam ships from Clayton, NY through the early 20th century when it closed and was ultimately torn down. Today a community house and post office sit on the former site of the hotel. The post office operates yearly from June until September. An annual "Fish Fry" is hosted on the grounds of the community house every summer; the event takes place on the first Saturday of July. Murray Isle is bounded by channels on both its eastern and western tips. The channel on the island's eastern tip, known as "The Narrows" separates Murray Isle and Wellesley Island. A small islet known as Wintergreen Island (formerly Whippoorwill Island) is connected by a footbridge along the southern length of Murray.
