If you can't stay longer, then the best way to make the most of a flying visit to this World Heritage Site is to take a free walking tour of the city centre with one of the Mayor of Bath Honorary Guides.
Tours depart from outside the entrance to the Pump Room daily at 10.30am and 2pm (Saturdays at 10.30am only) and last for approximately 2 hours. All tours include Bath's major sights such as Pulteney Bridge, The Circus and the Royal Crescent, and will give you a fascinating insight into how Bath became the world-class attraction it is today.
If walking is not your style, hop-on/hop-off open-top bus tours of the city depart at regular intervals and visit all the major sights.
After your tour, a visit to the world-famous Roman Baths is an absolute must-do. Based around Britain's only naturally hot springs, the Romans built a magnificent temple and bathing complex that still flows with mineral-rich thermal water. See the water's source and walk where Romans walked on the ancient stone pavements. The extensive ruins and treasures from the spring are beautifully preserved and presented using the best of modern interpretation.
Before leaving, stop for lunch or afternoon tea in the Pump Room, alongside the Roman Baths. Regarded as the social heart of Bath for more than two centuries, the Pump Room is a striking neo-classical salon and is the place to which hot Spa water is drawn for drinking. Today the Pump Room contains a restaurant that is open daily for lunch and light refreshments.
And if you've got time before your coach or train departs, pop into the Tourist Information Centre in Abbey Church Yard to pick up a memento of your visit, or better still to book accommodation for a longer stay next time.
