Hotels in Southeastern Ontario, Canada

Southeastern Ontario stretches along Lake Ontario and the St. Lawrence River, famous for the 1,800 islands of the Thousand Islands and historic Kingston, a former capital with limestone buildings and Fort Henry. The climate brings warm summers (75-85°F / 24-30°C) perfect for boat tours through the St. Lawrence River's narrow channels and swimming at Sandbanks Provincial Park's freshwater sand dunes in Prince Edward County, while snowy winters (15-30°F / -9 to -1°C) are ideal for ice fishing on the Bay of Quinte or skiing at Calabogie Peaks Resort. You'll find a different vibe between Kingston's 19th-century military history and Prince Edward County's over 40 wineries, with fall harvests and spring blooms offering quieter visits.
