Overview


Thousand Island Lakes is a breathtaking region known for its countless small islands, crystal-clear waters, and incredible outdoor recreation. It is a popular destination for boating, fishing, and sightseeing.

Located along the St. Lawrence River, this natural wonder is home to over 1,800 islands, each with its own unique charm and ecological significance. Some islands are large enough to support entire communities, while others are tiny, uninhabited outcrops covered in lush vegetation.

The region’s scenic beauty attracts nature lovers, adventure seekers, and history enthusiasts alike. Many of the islands feature historic castles, picturesque lighthouses, and protected natural reserves that provide habitats for diverse wildlife.

Boating is one of the most popular activities in the Thousand Island Lakes area, with numerous marinas, rental services, and guided boat tours available. Whether you are exploring hidden coves, fishing in the rich waters, or simply enjoying a relaxing cruise, the experience is unforgettable.

Fishing is another major draw to the area, with abundant populations of bass, pike, and muskellunge making it a favorite destination for anglers. The clean, nutrient-rich waters provide excellent conditions for both recreational and competitive fishing.

Visitors also enjoy kayaking, canoeing, and paddleboarding, as the calm channels between islands create the perfect setting for exploring at a leisurely pace. Many of the islands have designated picnic areas and hiking trails, allowing guests to step ashore and experience nature up close.

In addition to outdoor activities, Thousand Island Lakes is rich in history and culture. The region was once a summer retreat for wealthy industrialists, and remnants of their grand estates, such as Boldt Castle and Singer Castle, can still be visited today. These historic sites offer a glimpse into the luxurious past of the area.

Wildlife enthusiasts will find plenty to admire, as the islands serve as important nesting grounds for birds such as ospreys, herons, and bald eagles. The surrounding waters are home to various fish species, and the forests provide refuge for deer, foxes, and other native animals.
