Camping on Fire Island! No, Blanche, not that kind of camping - REAL camping. The National Seashore campgrounds at Watch Hill are a great way to experience the natural beauty and peace of Fire Island, the barrier island that protects much of Long Island's South Shore.
Reservations are a must, and sites go for about $20 a night. You don't reserve a particular site however, so the first task upon disembarking from the ferry is to claim your spot.
At the marina there is a interpretative center, store, bar and snack bar. Davis Park is a short walk. You can bring the family to the lifeguarded beach immediately adjacent to the campgrounds, or walk east on the beach to complete solitude and cothing optionality.
Bird and plant life abounds. There is also backcountry camping, but this is essentially a desert ecosystem, so you'll have to lug a lot of water with you. Fresh water and cold showers are provided at the campgrounds, along with charcoal grills and picnic tables.
One word of advice: bring lots of bug repellent -- mosquitoes can be a major problem.
