What are some options for exploring nearby islands from Portstewart?

Ballycastle is another resort town with a harbour and beach, from where campers can take a ferry to Rathlin Island, six miles out to sea. The island is a renowned bird sanctuary and ideal for exploring on foot or by bicycle to learn about the thousands of birds that visit the island, including puffins. You can make your visit a day trip or stay overnight—you just need permission from a landowner to camp, and both tent camping and glamping options are available.
