We could have tried the one-day £12 Charles Rennie Mackintosh Trail Ticket. Not only does it give you unlimited travel on the city’s subway and First bus services in Greater Glasgow but it also includes entry to the main Mackintosh attractions. If you limit your visits to The Glasgow School of Art and The Hill House, which will already take you a lot of time, this ticket will be well worth the purchase, for an adult entry to the School of Art will cost you £ 6.50 and one to the Hill House £8
