Mary Island State Park

Mary Island State Park offers a unique island escape for those looking to immerse themselves in the natural beauty of the Saint Lawrence River. Situated just 2.7 miles from the bustling village of Alexandria Bay, this state park provides a serene, remote setting perfect for campers who want to experience the river environment firsthand. The park is accessible primarily by boat, offering a quiet, secluded atmosphere that feels worlds away from the mainland.

This destination is ideal for tent campers and those who enjoy a true outdoor experience, as the campground is primitive and does not offer utility hookups. It is a beginner-friendly location for those looking to practice their wilderness camping skills in a manageable, scenic setting. Because the park is open year-round, it provides a flexible option for outdoor enthusiasts to visit throughout the different seasons.

Visitors should come prepared for a rustic experience, as the site offers basic accommodations for tent and car camping. Whether you are looking to fish, explore the river, or simply enjoy the peaceful sounds of the water, Mary Island serves as a perfect base camp for your Thousand Islands adventure.
