Across Europe, only two aquaparks publish a blue–red–black slide rating — both in France

A multilingual live web scan on 27 August 2026 verified 2 European parks whose own published pages use the blue/red/black difficulty classification for water slides. Together they document 15 classified named tracks: 6 blue, 4 red, 5 black. This is the set the scan could verify, not a census — Europe has no comprehensive registry and many parks use other rating systems or publish none.

Classified tracks per park, one segment per difficulty level — hover a segment for the slide names behind it

blue — easiest red — intermediate black — hardest

O'Gliss Park in Le Bernard holds the larger classified inventory — 9 of the 15 verified tracks, including 3 black-rated slides such as Looping Rocket and Free Fall. oglisspark.fr

Atlantic Park in Seignosse runs an unusually even 2/2/2 split — exactly two slides at every level, from Flash Tube up to Crazy Kamikaze. levieuxport.com

Blue is the most common rating window-wide with 6 tracks, but black outnumbers red 5 to 4 — the hardest tier is better stocked than the middle one. oglisspark.fr

Each named attraction counts as one track even where it has several physical lanes — a racer such as Twister Racer counts once. levieuxport.com

Live web scan performed 2026-08-27 across multilingual park websites and travel pages; 2 parks and 15 named tracks verified. A track is one named slide/attraction with a published blue, red, or black difficulty rating — multi-lane racers count once. Parks that use other rating systems or publish no classification are out of scope; this is the verified set, not a European census. Nothing was cut for space.
