Perhaps Miami's most popular attraction is its incredible 35-mile stretch of beachfront, which runs from the tip of South Beach north to Sunny Isles, then circles Key Biscayne and numerous other pristine islands dotting the Atlantic. The characteristics of Miami's many beaches are as varied as the city's population: There are beaches for swimming, socializing, or serenity; for family, seniors, or gay singles; some to make you forget you're in the city, others darkened by huge condominiums. Whatever type of beach vacation you're looking for, you'll find it in one of Miami's two distinct beach areas: Miami Beach and Key Biscayne. And in keeping up with technology, Miami Beach is now officially a hot spot -- as in a wireless hot spot, offering 95 percent coverage outdoors (70 percent indoors) of free Wi-Fi throughout the entire city and yes, even on the sand.

Miami Beach's Beaches -- Collins Avenue fronts more than a dozen miles of white-sand beach and blue-green waters from 1st to 192nd streets. Although most of this stretch is lined with a solid wall of hotels and condos, beach access is plentiful. There are lots of public beaches here, wide and well maintained, complete with lifeguards, bathroom facilities, concession stands, and metered parking (bring lots of quarters). Except for a thin strip close to the water, most of the sand is hard-packed -- the result of a $10-million Army Corps of Engineers Beach Rebuilding Project meant to protect buildings from the effects of eroding sand.

In general, the beaches on this barrier island (all on the eastern, ocean side of the island) become less crowded the farther north you go. A wooden boardwalk runs along the hotel side of the beach from 21st to 46th streets -- about 1 1/2 miles -- offering a terrific sun-and-surf experience without getting sand in your shoes. Miami's lifeguard-protected public beaches include 21st Street, at the beginning of the boardwalk; 35th Street, popular with an older crowd; 46th Street, next to the Fontainebleau Hilton; 53rd Street, a narrower, more sedate beach; 64th Street, one of the quietest strips around; and 72nd Street, a local old-timers' spot.

From Desert Island to Fantasy Island -- Miami Beach wasn't always a beachfront playground. In fact, it was a deserted island until the late 1800s, when a developer started a coconut farm there. That action sparked an interest in many other developers, including John Collins (for whom Collins Ave. is named), who began growing avocados. Other visionaries admired Collins's success and eventually joined him, establishing a ferry service and dredging parts of the bay to make the island more accessible. In 1921, Collins built a 2 1/2-mile bridge linking downtown Miami to Miami Beach, creating excellent accessibility and the longest wooden bridge in the world. Today Miami Beach has six links to the mainland.

Key Biscayne's Beaches

If Miami Beach doesn't provide the privacy you're looking for, try Virginia Key and Key Biscayne. Crossing the Rickenbacker Causeway ($1.50 toll), however, can be a lengthy process, especially on weekends, when beach bums and tan-o-rexics flock to the Key. The 5 miles of public beach there, however, are blessed with softer sand and are less developed and more laid-back than the hotel-laden strips to the north. In 2008, Key Biscayne reopened the historic Virginia Key Beach Park, 4020 Virginia Beach Dr. (tel. 305/960-4600;, the former "colored only" beach that opened in 1945 and closed in 1982 because of high maintenance costs. After an $11-million renovation, the 83-acre historic site features picnic tables and grills, shoreline renourishment, a new playground for children with special needs, and a miniature railroad. The beach eventually plans to open a civil rights museum as well. Open from sunrise to sunset daily, with free admission.
