Narechen Hot Springs is located in Narechen, Plovdiv Province, Bulgaria. The bicarbonate water surfaces at 38°C with a pH of 8, feeding indoor pools alongside a sauna.
Insider tip — Narechen lies in the Rhodope Mountains near Asenovgrad, where low-mineralised sodium-bicarbonate springs at 38 °C emerge in a deep river gorge and feed a cluster of sanatoriums from the Bulgarian socialist period. The gorge setting makes the spa unusually scenic, with vertical limestone walls and conifer forest rising above the bathing complex. Day-trippers from Plovdiv (40 km north) frequently combine a soak at Narechen with a visit to the dramatic Asen's Fortress ruins nearby.
