Best Tours (Los Angeles), Beverly Hills

The experts behind Best Tours don't take their superlative lightly. Their array of international tours—based in cities from Sydney to London to LA—show off a deeply-researched array of hidden gems, always clustered around a theme. Guides can take groups to see beautiful local street art, decadent chocolate shops, or haunted spots like the White House, named for the color of its ghosts. There's no pressure to walk the whole way, either. While some tours are walking tours, on others tourists get chauffeured around town in private cars.
