Long Island's North Shore has many inlets and bays. Most have free access to put the boat in the water. Some towns require a town sticker or you can pay for day access. If you are computer savvy you can look for local streets to park on. The bays are sheltered and are usually calm. However, you must keep an eye out for boats and jet skis. You must also be careful during high tide. If you go to far into the estuary you may get caught on a mud flat and have to wait for the next tide to get out. On calm days you can head out to the open sound and paddle to Connecticut, 12 miles one-way, and take the ferry back. There are many other places on LI. We are surrounded by water. The Island is 120 miles long and 42 miles wide.
The are a couple of B&Bs in town and a couple of motels.
