Best Water Parks in Europe for Kids: 9 Compared on Age, Height and Supervision Rules

<p>Which water park suits your family depends on your children's ages and whether they can swim. These nine parks all have a page on our site and a specific rule that helps parents, such as a free age, a slide limit or a supervision rule. They're listed alphabetically, not ranked.</p>

Which water park is best depends on your children’s ages and whether they can swim, so we haven’t ranked these. Our criterion is simple: a park appears here if it has a page on our site and we could find a specific rule that helps parents, such as a free age, a slide limit, a supervision rule or a dedicated area for small children. The nine parks below are in alphabetical order. A big park that’s missing may simply not be on our site yet.

Quick answer

• Dedicated toddler area: Tropical Islands has Kraki Beach, and Aquapalace Praha has a children’s paddling pool.
• Published slide limits by age and height: Rulantica sets them for each attraction.
• Open all year: Siam Park says it opens 365 days a year, and Therme Erding is open year round.
• Free for small children: under 4 at Tropical Islands, up to and including 3 at Therme Erding, and under 1 m at Skara Sommarland.

How to choose

• Is your child a non-swimmer? Check rules such as Skara Sommarland’s limit of two non-swimming children per adult.
• Do you have an under-4? Look for a free age and a dedicated area, as at Tropical Islands.
• Do you have an under-8? Compare slide limits at Rulantica before you promise anything.
• Do you need winter swimming? Consider the parks open all year, or read theme parks open in winter in Europe.
• Bring swim nappies. Lalandia requires them for all under-3s.
