Along Sunset Boulevard, Wilshire Boulevard, Hollywood Boulevard, and various other locations throughout Hollywood and the Los Angeles area, you'll find some of the world's trendiest nightclubs. As with any trend, the hot place to be seen in L.A. changes quickly, so ask your hotel's concierge to recommend the best clubs to visit. Most clubs have a dress code, and you must be either eighteen or over twenty-one to get in. Some offer live entertainment, while others feature some of the country's best-known DJs.

No matter what type of music you enjoy or what crowd you like to party with, chances are there's an L.A. club to satisfy your desires. Los Angeles for Visitors (http://golosangeles.about.com) lists the city's best nightclubs by type. You can also pick up a free copy of the LA Weekly (www.laweekly.com) at any hotel or newsstand for information about the club scene and a detailed calendar of events for the entire Los Angeles County area.
