Erftlagune

The Erftlagune is a year-round leisure bath run by the Kolpingstadt Kerpen, which also operates the Hallenbad Kerpen and the Freibad Türnich; the operator's own name for it is ERFTLAGUNE Vierjahreszeiten-Bad, and its address is Bruchhöhe 20, 50170 Kerpen, in the Sindorf district. The water is ordinary heated tap water: the operator names no thermal spring, no mineral source and no brine, and it describes no sauna.

Indoors the layout is built around an Erlebnisbecken of roughly 180 m² at about 30 °C, fitted with underwater massage jets, massage benches, recessed underwater loungers, a flat-jet shower and a neck shower. A 50-metre Großwasserrutsche with banked curves discharges into this pool, ending in a wide run-out the operator calls a Rutschensofa. A swim channel links the Erlebnisbecken to the outdoor pool, so the indoor and outdoor water can be used in one visit. Beside it a Warmsprudelbecken is held at about 34 °C. For lane swimming there is a 25-metre Sportmehrzweckbecken of 318 m² at about 28 °C, lit by underwater floodlights, with a 1-metre springboard and a 3-metre platform over water 3.40 metres deep. The indoor toddler area has two shallow basins at about 32 °C with a water-squirting animal and a small slide, and a baby changing room next to it.

Outdoors the Vierjahreszeitenbecken measures about 192 m² and is held at about 30 °C, which the operator states allows use in snow and ice; it contains a current channel, a bubbling section with massage benches in the middle, a water mushroom, underwater massage jets and an underwater massage bench. A five-lane Sportmehrzweckbecken of about 318 m² is open in the summer season only, alongside a lawn. The outdoor paddling pool of about 100 m² sits at about 30 °C and carries a free-jet mushroom, a squirting animal, a mini spouter and a slide ramp. Catering is the Café-Snackbar Kiwi with a terrace.

The bath is given over to schools and clubs during the day, with early swimming from 6 to 8 in the morning; public opening is Thursday and Friday 14:00-21:00 and Saturday, Sunday and public holidays 11:00-19:00, with early swimming Tuesday to Sunday 06:00-08:00.
