A fun and cheap way to entertain yourself and the kids, especially on a rainny day. Spent a few days in Marianske Lazne with a toddler and as the weather was not the best, this public indoor pool came in very hand. Very clean area, clean showers, warm water in both pools (+-28C), a big pool for adults and a smaller one for kids. They even have a tobogan, great fun foe a very reasonable price (kc70/h for adults).
