Spend time exploring the riverbanks of the River Ouse, which splits York in two. In addition to its numerous lovely gardens, you can see wonderful examples of riverside architecture, such as the majestic 15th-century Guildhall.
Another view of York is from a cruise on the river, either on an all-weather passenger boat or on a self-drive motor boat. In the summer, cruises also go to Bishopthorpe Palace, the riverside residence of the Archbishop of York.
