At 23 hectares, St James's Park is the second-smallest of the eight royal parks in London, falling behind only Green Park. But this green space more than compensates for its petite size with its meticulously groomed grounds. Spectacular views of the London Eye, Westminster, St James's Palace, Carlton House Terrace and Horse Guards Parade make this park a stunning sight to behold, with the view of Buckingham Palace from the Blue Bridge spanning the central lake being especially breathtaking.
