The diverse climate has four distinct seasons. Summers are comfortable and warm, with daytime temperatures averaging in the mid 70s to mid 80s (degrees F) and cooler evenings. The weather is moderately cool and sunny in springtime and autumn, when spectacular fall foliage attracts thousands of visitors. Cold, snowy winters create a wonderland of magnificent scenery.


1. The region actually has 1,864 islands. To be classified as an island, a land mass must be above water 365 days a year and support at least one tree. Many islands are privately owned, but some can be rented for a weekend, week, month or season. Many others have public and private campgrounds.

2. Thousand Island salad dressing was created in this region. The origin is subject to debate: one tale says it was created by a ship's chef; the other story credits a fishing guide's wife.

3. Two historic island castles are open for tours: the 120-room Boldt Castle, built by NYC hotel executive George C. Boldt, and Singer Castle, the summer home of Frederick Bourne. Both men were self-made millionaires who began their careers at entry level positions.


Whitewater Rafting and Kayaking: The Black River Canyon features class III and IV rapids that offer thrilling adventures and national competitions including the famous Blackwater Challenge.

Fishing:  Anglers come from around the world for trophy-sized catches and fishing derbies on Lake Ontario, the St. Lawrence River and smaller tributaries throughout the region year-round, including great ice-fishing in winter.

Hunting: State lands, including wildlife management areas, state forests and state parks are open for hunting during the appropriate seasons. Find information at

Hiking and Biking: Six hundred pristine acres on Wellesley Island include miles of scenic shoreline hiking trails.

Nature Centers: The Minna Anthony Common Nature Center is one of the largest nature centers in the state park system. Wildlife sightings include Bald Eagles and waterbirds such as osprey that nest in the park.

Winter Sports: In the Snowbelt, east of Lake Ontario, lake-effect snow covers the Tug Hill Plateau with an annual average of 300 inches. At its edge, Winona State Forest has over 30 miles of nature trails and unplowed roads ideal for snowmobiling, snowshoeing, cross-country skiing and even dog-sledding.
