Familien- und Erlebnisbad Heringhausen

The Familien- und Erlebnisbad Heringhausen is the indoor bath of the Gemeinde Diemelsee, at Kirchstraße 6 in 34519 Diemelsee-Heringhausen in northern Hesse, on the shore of the Diemelsee reservoir at the northern edge of the Sauerland. The municipality runs it alongside the lake's bathing beaches and the open-air pool at Vasbeck, and describes it as open all year for bathing, swimming, splashing and sauna.

The water side consists of a 29 °C indoor pool and an outdoor pool with a lounging lawn used in the summer months, a separate bubble pool, floor bubblers in the large basin, a massage shower and massage jets. The children's bathing landscape is a low basin at 32 °C with a slide and a water dolphin, aimed at splashing and first contact with water rather than at any water-park attraction. A pool lift is installed for bathers with physical impairments. Alongside open bathing the municipality runs free aqua-fitness classes, two of them reserved for seniors and one open without registration, Seepferdchen swimming courses from age five, and children's birthday parties that can be combined with a visit to the Visionarium exhibition with its ball pool and quiz.

The sauna area holds a Roman steam bath and a Finnish dry sauna with colour therapy, a rest room and a brine grotto, and the operator lists it both as a general sauna and as a women's sauna. Sauna hours are short and limited to two days a week, Monday from 17:00 to 21:00 and Thursday from 15:00 to 21:00. Bath hours are longer: Monday and Thursday 13:00 to 21:00, Tuesday, Wednesday and Friday 09:00 to 21:00, Saturday 09:00 to 19:00, Sunday and public holidays 09:00 to 18:00, with last admission an hour before closing.

The water is plain heated water; nothing on the operator's pages describes a thermal or mineral source, and the brine grotto belongs to the sauna area rather than to any bathing basin.
