Sportcentrum De Waterkanten is an indoor swimming and training complex in Lisse with a 25-metre competition pool, instruction and recreation pools, a whirlpool, a rapid feature, a toddler pool, a 60-metre slide, and a low diving board. It works well for laps, lessons, warm-up laps, and family swimming. The setting is fully controlled and chlorinated, so the planning focus is on opening hours, lane use, and facility access rather than weather or water movement.
