As one of the most densely populated cities in the world, San Francisco is a bustling hub of excitement and adventure for visitors. While the breathtaking Golden Gate Bridge serves as the signature landmark of the city, there are countless number of museums and attractions to enjoy, such as Golden Gate Park, the Mission District, Fisherman's Wharf, Yerba Buena Gardens, Alcatraz Island and more. The Bay Area has become the center of the technology universe, making San Francisco home to some the top young minds in the world. There are hundreds of superior restaurants and farmers markets that cater to both residents and visitors alike. Those that have seen the city in movies and TV shows are familiar with its signature hills and cable cars. These cable cars provide easy access to Russian and Nob Hills, though many may also want to savor the garden-lined stairway walks of beautiful Telegraph Hill. Arts and culture are vital to the city, as museums such as the California Academy of Sciences and the Asian Art Museum showcase the area's commitment to its signature communities. The Yerba Buena Arts district is home to hundreds of collections and exhibitions that spotlight the eclectic nature of the city. The Barbary Coast Trail displays the city's mix of modern and historic structures, while linking up to Union Square and Chinatown, home to some of the finest Asian cuisine in the country. The trail also allows you to experience Coit Tower, a landmark in the San Francisco skyline that sits atop Telegraph Hill while looking over the beautiful city waterfront. Though the city is known for its dense fog, its mild climate makes it ideal for all types of walking tours.
