10. Bath, England: Rooftop Views and Roman Waters

Tap into Britain's only natural thermal hot springs at the contemporary Thermae Bath Spa. While located in a historic spa city, this modern facility offers relatively affordable spa sessions compared to private luxury options. The highlight is the stunning open-air rooftop pool with panoramic views over the city, including Bath Abbey. Access includes the multi-sensory Wellness Suite and the Minerva Bath. It provides a unique blend of history (using the same waters the Romans did) and modern spa relaxation.
