Thermae Bath Spa

Britain's only natural thermal spa where you can bathe in mineral-rich waters at 33-35°C in modern pools fed by the same springs used by Romans. The rooftop pool offers views across Bath's skyline while you soak in naturally heated spring water. It ranks among Bath's most visited sights, and for good reason - most itineraries include it on day one. Tickets cost £47 for 2 hours, £57 for 4 hours, treatments extra and 2-4 hours minimum session is enough to see everything without rushing.

Experience the same thermal waters Romans used, with modern spa facilities and city views. That puts it near the top of any Bath visit, and it deserves the spot. Combine it with The Roman Baths and Bath Abbey - they are close enough to walk between and together make the strongest half-day in Bath. Afternoon tends to work best here.
