Stony Brook Harbor Kayak & Paddleboard provides a great experience. This is not a tour, you are on your own. Groups are welcome.They also use Wilderness Systems' Pungo Kayaks for the single kayaker, which in my opinion provides a very comfortable and stable ride as you glide across the very calm waters of Stony Brook Harbor. Tandem kayaks are also available. The scenery is also very amazing from the Historic Stony Brook Grist Mill and water falls to the Harbor itself with its many species of birds. You will navigate along the coast in a very peaceful environment. This is my zen place! Nick (the owner) is an awesome person who sincerely wants his clients to have a great experience. He wears his enthusiasm on his sleeve. Groups are very welcome. Their tag line "Another day in paradise" says it all. However, due to the tide schedule, their hours of operation change everyday. Check out their rental schedule on line. You must call or text to make a reservation. Unfortunately, bathrooms are not readily available.
