Golden Gate Park, San Francisco

In the late 1800s, a Scotsman named John McLaren transformed more than 1,000 acres (405 hectares) of sand dunes into a wondrous haven in the midst of busy city life. Stretching over 50 blocks from Stanyan Street to the Pacific Ocean, the lush landscaping features ever-changing settings at every turn. There are trails for walking, jogging, biking, horseback riding, as well as a golf course, lawn bowling greens, a lake with paddle boats, soccer fields and a baseball diamond. For those seeking less strenuous diversion, check out the California Academy of Sciences and an authentic Japanese Tea Garden. For families with children, there are playgrounds, a live buffalo reserve and a carousel. A Shakespeare Garden can also be found by going down a hidden lane in the park.
