Discover Serene Granite Islands and Crystal Waters on the St. Lawrence River
Scattered across the St. Lawrence River where it meets Lake Ontario, Thousand Islands National Park protects a stunning chain of over 20 granite islands and countless smaller islets. This Parks Canada gem sits near Mallorytown Landing, about 30 minutes east of Gananoque, and offers one of the most visually striking waterscapes in eastern Ontario.
What Makes Thousand Islands National Park Worth Visiting?
The park’s defining feature is its dramatic geology. Ancient Canadian Shield granite pushes through the river’s surface, creating wind-sculpted islands draped in white pine, red oak, and pitch pine. The water itself shifts between deep emerald and slate blue depending on the light, and visibility is remarkably clear in sheltered bays. You’ll find some of the best kayaking in Ontario here, paddling between islands where great blue herons stand motionless along rocky shorelines.
How Do You Get Around the Park?
Since most of the park is water-accessible only, you’ll need a boat or kayak. Parks Canada operates a water taxi from Mallorytown Landing to several islands, including McDonald and Georgina. Camping is available on designated islands with oTENTik structures for those who want a roof overhead without sacrificing the waterfront experience. Reserve early for summer weekends, as sites fill quickly by late spring.
The park’s Day Use area at Mallorytown Landing is free to access and includes a visitor centre, swimming area, and short hiking trails along the riverfront.
Fall brings fewer crowds and brilliant foliage reflecting off the St. Lawrence, making September and early October ideal for a quieter visit.
Seasons
Late April–June: wildflowers bloom, migratory birds arrive, and weather is mild—ideal for hiking and boating.

September–October: calm waters, cool air, brilliant fall foliage, fishing and photography with fewer crowds.
