La Băltoacă — Romanian for 'At the Puddle' — is a naturally occurring bicarbonated mineral spring or seep in Romania, its endearingly modest name acknowledging the small, pooled form in which the geothermal water collects at the surface. Such intimate, spontaneous mineral water sites are characteristic of Romania's vast geothermal landscape, where warm, mineralised water often appears in unexpected places, tucked into hillsides, meadows, or riverbanks. The spring is appreciated locally as a point of natural heritage and gentle therapeutic value.
Insider tip — La Baltoacea is a small warm-water pool fed by bicarbonate springs along the southern edge of the Portile de Fier national park. The pool sits within a lush riverside microclimate where the Danube gorge moderates temperatures year-round. The site is informal with minimal infrastructure, beloved by hikers on the Danube trail. Bring your own towel and water shoes as the rocky bottom can be uneven.
