Regent's Park - London. Expansive, peaceful, picturesque, and a surprise around every turn for the newcomer. And I was lucky enough to attend a semester of college situated right in the middle of the park. No trouble finding a private spot to study or just "cop a squat" here!
Hyde Park covers an area of 625 acres, split into two pieces – Hyde Park forms the eastern half (350 acres). Anything west of the Serpentine is known as Kensington Gardens (275 acres). The park was the site of the Great Exhibition in 1851, and is also known for Speakers Corner. During the time of the Suffragetes, protests were held in the park
