Izbucul Izbândiș (Izbândiș-forrás)
Karst spring near Șuncuiuș in the Pădurea Craiului, home of Romania's cave-diving depth record. Salvamont Cluj divers reached 121 m in 2022 and 129 m in February 2024, turning back where the passage narrows because of decompression; it continues downward. The water is no more than 9 °C. Earlier underwater exploration of the spring cost a life.
