While on vacation in London, we stayed at the nearby Sheraton Grand London Park Lane. One morning, we decided to go see the Changing of the Guard at Buckingham Palace. After awhile, we started walking towards St. James's Park.
Given the number of parks in London, St. James's Park is one of many but in my mind, it stuck out the most. The park has a small lake and a large number of birds waterfowl, including pelicans, wrens, mallards, Tufted ducks, various British duck species, swans (including black swans), and geese. There are also an abundance of grey squirrels here. The animals are not particularly afraid of people and will come up to you if it looks like you have food. In fact, two squirrels climbed on my BF thinking he had something to give them.
At the center of lake is the Tiffany Fountain. On special occasions, the fountain jet is illuminated in color. There's a bridge here called Blue Bridge that offers an amazing panoramic view eastward of the Horse Guards Parade, Old War Office, and Whitehall Court; southward of the London Eye, Shell Tower, and the Shard; and westward of Buckingham Palace.
This is a great place to leisurely walk around and take in the lovely views. Since it is next to all things touristy, it can get to be a bit crowded but it's well worth a stroll.
