If you are referring to the historic Roman Baths in Bath, England, the answer is a definitive no. Swimming in the Great Bath and other pools at the historic site has been strictly prohibited since 1978 for health and safety reasons. The water is untreated, contains dangerous levels of bacteria, and the lead-lined pools are not suitable for modern bathing. While you can walk around the stunning ruins and see the steaming green water up close, you cannot touch it. However, if you want to experience the same natural thermal waters that the Romans did, you can visit the nearby Thermae Bath Spa. This modern facility is located just a few blocks away and features a spectacular rooftop pool where you can soak in the warm, mineral-rich spring water with views over the city. Additionally, the Spa Village at The Gainsborough hotel is the only other place in the UK where you can legally bathe in these specific thermal waters. For those who enjoy "wild swimming," the nearby Warleigh Weir offers a more natural, cold-water experience in the river, but the actual "Baths" of Bath are preserved strictly as a museum and archaeological monument.
