For New Yorkers, a trip to Long Island is an escape to the sand - specifically Jones Beach (6.5 miles long, parking for, gasp, more than 20,000 cars) and Robert Moses State Park (5 miles long, 8,000 cars). But another 100 or so beaches line Long Island, some of them with remote outer beaches (Cedar Point in The Hamptons among them) favored by the surf-fishing/4-WD set. Not surprisingly, the Hamptons are blessed with the finest beaches, although exclusivity sometimes carries a hefty price tag: seasonal beach permits can range from $200 to $500. One way to beat the crowds? Bike to Wainscott Beach. The neighboring real estate is pricey, the parking facilities minimal, and the beach is priceless.
