Tons of lakes scattered between Canada and the USA on Lake Ontario provide endless recreation opportunities. Long Point State Park is a nice little park that juts out into the lake and is known for water activities. Not a ton to do on site if you don't have a boat or don't want to swim, but very close to lots of options. Exceptional birding in the area. Camp right on the water. Pretty standard facilities, nice and clean as you'd expect from a NY State Park. Not super shady but climate is pretty mild. Bring bug spray (as all over NY!).
