Commercial, public service vehicles and coaches are not permitted on park roads within the Royal Parks unless approved by The Royal Parks for official business.
However, The Royal Parks recognise the importance of St James's Park and their associated buildings as a visitor attraction and thereby permit coaches through St James's Park by advance purchase of a permit.
Unfortunately, coach parking has been cancelled indefinitely.
Coach drive-through permits can be purchased from the St James's Park Office for £7.20 (inclusive of VAT).
On purchase of a drive-through permit single-decked coaches are permitted to enter St James's Park via Admiralty Arch to drive along The Mall and to exit the park via Constitution Hill to Hyde Park Corner.
Stopping on roads within the parks is not permitted. Double-decked coaches are not permitted in the parks. Coaches are not permitted on any other road in St James's Park, The Green Park or in Hyde Park.
On Sundays and Public Holidays the Mall and Constitution Hill are closed to traffic.
