Read more about this location
Last Chance Splash Waterpark & Pool is Helena's main public warm-weather water-play destination, combining a splash deck with a zero-depth pool, lazy river, lap pool, diving well, and two waterslides. The splash area includes water guns, rainbow sprinklers, geysers, and other spray features that work especially well for mixed-age family visits. Because it is a full municipal pool complex rather than a standalone spray park, families get more amenities than a typical splash pad, including concessions, life jackets on request, and family changing rooms. It is a strong choice for families who want a longer summer outing and don't mind paid admission.
