University Parks, Oxford
Huge parts of Oxford are green - meadows, parks, gardens, college lawns... One of them, and also one of the nicest places for a walk is the University Parks which stretch out between River Cherwell in the east, Parks Road in the west, Lady Margaret Hall (Oxford's first women's college) in the north and South Parks Road in the south. While parts of the park are well-kept and rather urban, others are wilder and more natural. River Cherwell's many arms flow through the park, whirling waters with ducks, swans and geese swimming on them; knotty trees growing on its shore. Dogs run along the water fetching the sticks that somebody threw for them; students go running, elderly people enjoy a quiet moment on one of the many benches... Typical things to be seen in a park, but lovable nonetheless.
University Parks is also a place of bio-diversity: More than 800 kinds of trees are found there! Similarly unusual is the Victorian cricket pavillion which to me resembled more a seaside residence hotel on the German island of Rügen than a sports grandstand.
One last fact: Don't be confused if Oxonians want you to join them for a walk in Mesopotamia - a part of the park bears this name as it "resembles" the original Mesopotamia: It is located between two arms of River Cherwell, hence the name (deriving from Greek meso potamos - between two rivers). Oxford's Mesopotamia, or more specifically a place called Parson's Pleasure, used to be a men-only nude bathing spot until 1991. A similar spot for ladies, called Dame's Delight, was officially in use until the 1970s. Given the not-only proverbial English prudery, however, I doubt that these places were actually used very often.
The Parks is one of the nicest areas of Oxford. I often go jogging here, and in summer it's a great place to relax, read and play sport (though not all at once!)
