Grass Point State Park is on a point of land that projects into the American Channel of the St. Lawrence River, known for some of the best fishing in the country. The park is a popular spot for campers and day-users, who come to boat, swim, fish, picnic, or just to relax. There is a marina and boat launch, an area is available for games, and the sandy beach and shallow water are excellent for children.

Located on the west side of the beach is the Grass Point cottage, a full service accommodation. The two-story cottage has a bathroom with shower, kitchen with refrigerator, stove, microwave, cooking and eating utensils. Bedding, pillows and linen are also provided. The screened-in porch has some outstanding views of the river and sunsets.
