Hollywood is fun to explore on foot but, by far, the best way to see Hollywood and all of its sights is by taking a narrated bus tour of the city, especially if it's your first visit. Visitors will find lots of companies with kiosks on Hollywood Boulevard touting their tours as the best available. In fact, many of them are very good and will provide you with an excellent overview of the landmark attractions in the city.
Some of the tours are fairly short while others will consume the better part of the day. Which you choose will depend on just how star-struck you might be! Most of the tours also venture into nearby neighborhoods, particularly Beverly Hills, the area where many stars make their homes and have for decades. Though the buses aren't allowed to come to a complete stop in front of the houses, you'll still get a good look at them.
