Stony Brook State Park is absolutely stunning year round, but my favorite time to visit is on a mild November day, once the crowds and heat of summer have slipped away. There have been times where we have had the park nearly to ourselves! Be advised, though many of my photos show people in the water, wading into the water is not allowed and there could be fines issued for doing so.
From the NYS Parks website
“Stony Brook State Park’s terrain comprises hilly woodlands, a deep gorge with rugged cliffs overlooking three waterfalls and fascinating rock formations. Visitors can hike rim, gorge or nature trails, play tennis on park courts, or picnic. Some winter hiking is allowed, but not on the gorge or rim trails.”
