Best Water Parks in the Algarve: Aquashow vs Slide & Splash (2026)
There are two big water parks in the Algarve: Aquashow in Quarteira and Slide & Splash near Lagoa. We went to both this summer, and honestly, they’re pretty different. Here’s how they compared.
TL;DR
- Go to Aquashow if you want thrills. It has a crazy fast electric roller coaster, steep slides with shorter queues, and a bunch of theme park style rides.
- Go to Slide & Splash for a more varied, relaxed day. It has more variety in its slides, a better lazy river, more places to chill (like the hot tubs), and it’s a bit prettier.
- At both: don’t buy the food. Bring your own, it’s allowed.
Aquashow
Aquashow is just outside Quarteira, close to Vilamoura. It’s a water park, but it also has proper rides, which I didn’t expect.

The best one by far is the Flash Coaster. It’s an electric powered roller coaster and it gets insanely fast and twisted. I did not expect something like that at a water park. If you only do one thing there, do this.
There’s also a rotating pendulum swing (the Top Swing), a cart ride that crashes down into the water, and another coaster called the Watercoaster. Then there are the slides. The steepest ones are really good and really fast. They’re over in a few seconds, but the queues for them were shorter than at Slide & Splash, so we went on them quite a few times.
If you’ve got kids with you, there are lots of smaller slides and play areas for them too.
The food was the weak point. They sell food and drinks, but it’s fairly expensive for what it is and it wasn’t very tasty. You’re allowed to bring your own (just no glass bottles), so I’d just do that.
Slide & Splash
Slide & Splash is near Estômbar, in Lagoa, between Portimão and Carvoeiro. It’s the bigger of the two, and you notice it. It’s also a bit prettier. Even though it was busy, we found a nice spot with not many people around.

The rides are great. There are loads of fast slides (Kamikaze, Black Hole, Tornado and so on), and there’s a race slide with several lanes side by side. We did a lot of races on it. When we needed a break, we went to the hot tubs or just floated around on the lazy river for a bit. The lazy river here is better than the one at Aquashow.
The wait time for the biggest slides was considerable, but not too bad. Go early and do the big ones first.
The food wasn’t great here either. I guess that’s just how it is at these parks. You can bring your own food and drinks, just no glass or alcohol, and people were eating on the grass or on their sun loungers.
Which one is better?
Honestly, both are worth it. It just depends on what you want.
Aquashow is the better pick if you’re mainly after the adrenaline. The Flash Coaster alone is worth going for, and the shorter queues for the steep slides are a big plus.
Slide & Splash is the better pick if you want a bit of everything. There’s more variety in the slides, the lazy river is better, there are more places to just chill, and the park is a bit prettier overall. It’s also bigger, so it’s easier to find a quiet spot.
It also makes sense to go to whichever one is closer. Aquashow is easier to get to from Vilamoura, Quarteira or Albufeira, and Slide & Splash from Portimão, Carvoeiro or Lagos.
Prices and practical stuff
Prices are pretty similar at both parks. In 2026 an adult ticket was €32–38 depending on the season, kids and seniors paid a bit less, and kids under 1 m got in free. July and August are the most expensive months. You can check the current Aquashow prices and the current Slide & Splash prices on their websites. At Slide & Splash you get 10% off if you book online before the day of your visit.
Aquashow is open from 1 May to 30 September, 10:00 to 18:00 in 2026. Parking is free, and lockers are €5 plus a €5 deposit.
Slide & Splash has parking and lockers, and you can rent a cabana if you want some private shade.
