Tervise Paradiis is the largest water park in Estonia, a family favourite set right beside Pärnu’s beach. Under its glass roof, ticketed visitors enjoy a warren of pools, water slides, whirlpools, a wave pool and children’s play areas, along with saunas and a spa, making it a reliable rainy-day and year-round attraction. Attached to a hotel and with sea views from its upper levels, it is a splashy highlight for families visiting the resort town.
