If you're here at the right time, go to The Races. The York Knavesmire racecourse is one of the finest in the country. Races usually take place from Tuesday to Thursday at various times throughout the summer. The racecourse is about 15 minutes walk out of the city centre.
When it's not a race day, the road by the course (Knavesmire Road) makes a great place to park your car for free!
