Thermae Bath Spa

"Thermae Bath Spa provides the opportunity to bathe in Bath's naturally warm, mineral-rich waters as the Celts and Romans did over 2,000 years ago.  You can enjoy a two-hour spa session which includes full access to the 35.5˚ centigrade waters and flowing curves of the Minerva Bath, a multi-sensory Wellness Suite, and the open-air Rooftop Pool with spectacular views across the skyline of Bath. 💷 40-45 per person (it includes a towel), it's a good idea to book your visit in advance. Also, they have certain time slots for adults only, which can be perfect if you're looking for a serene and tranquil environment."

"One of the highlights of this spa is the rooftop pool, heated by the natural hot springs, overlooking the city rooftops. You can book a 2-hour pass, which gives you access to the saunas, pools and ice chamber. Booking an early morning session will be the quietest time to go. "
