Diana Resort

Diana Resort sits a few minutes from the center of Băile Herculane and pairs a renovated hotel with a balneal treatment center built around the area's sulfur-rich thermal mineral water. The wellness wing, called Aria Wellness, has been fully renovated and includes an indoor pool, a jacuzzi and sauna rooms, plus an outdoor pool used in warmer months. A children's pool area means families can swim alongside adults doing treatment or recovery stays.

Treatment here leans medical rather than purely recreational: the resort notes specialized medical staff and modern equipment for balneal therapy using the local thermal waters, which are concentrated in sulfur and used for treatment purposes rather than casual soaking. This makes Diana Resort more suited to guests booking a multi-day cure or recovery package than to someone looking for a single relaxing afternoon.

Access is tied to a hotel stay — this is a resort spa for hotel guests rather than a stand-alone day-pass facility. The property positions itself as a quiet base, with room types geared toward both short wellness breaks and longer treatment-focused stays. Restaurant service is part of the on-site offering, and the overall setup is pitched at couples and families alike who want pool, sauna and thermal treatment access without leaving the hotel grounds.

Published hours only list Sunday operation; confirm current daily schedules, treatment booking procedures and seasonal outdoor pool availability directly with the resort before planning a visit.
