Momin Prohod
Bulgaria
Spa town in western Bulgaria whose mineral waters rank among the most radioactive in Europe, Momin Prohod sits in the Kostenets–Dolna Banya Valley within the Sredna Gora mountain range, roughly a short drive from Sofia. The town functions primarily as a therapeutic and rehabilitation centre, and the waters here are second in radioactivity only to Narechenski Bani within Bulgaria.
