12 of the world's best water parks

Siam Park (Tenerife, Spain)
Siam Park is a Thai-themed water park on the island of Tenerife.
The park's most popular ride is the 91-foot-high (27 meters) Tower of
Power, on which riders plunge down a vertical drop before shooting
through an aquarium filled with stingrays and sharks.

Aquaventure Waterpark (Dubai, UAE)
As of 2013, this Middle East water park is home to the world's widest
water slide, the Middle East's longest river ride (2.3 kilometers in
length) and the Middle East's longest zip line.
The park's other attractions include several water coasters, a 2,296-
foot-long (700 meters) private beach and the Shark Lagoon, where
visitors can hand-feed rays.

Aquatica (Orlando, Florida)
One enormous wave pool obviously wasn't enough for the team behind
Aquatica, so they built two, side by side.
Elsewhere, the Dolphin Plunge water slide takes passengers on a white-
knuckle ride through a dolphin-filled aquarium and riders brave enough
to take on the Omaka Rocka blast down a series of flumes and funnels.
There's a sandy beach covered with 1,360 tons of soft, white sand and
South Seas-inspired gardens with more than 60,000 species of plants.

Area 47 (Innsbruck, Austria)
An Alpine lake is the location for this outdoor water park, which opens
from April to the end of September.
There are water rides, a diving tower and a hydro-speed slide.
On dry land there's a high-ropes course, bridge swing and climbing
wall.

Beach Park (Fortaleza, Brazil)
Beach Park's most famous ride is Insano, which ranks as the world's
tallest (135 feet/41 meters) and fastest (65 mph/104 kph) water slide.
Equally petrifying is Kalafrio, a giant half-pipe slide.
Younger visitors can check out an enormous big top-themed play area or
the Acqua Show, with water cannons, synchronized water jets and eight
water slides just for kids.

Caribbean Bay (Gyeonggi-do, South Korea)
You'll find four looping water slides and an enormous wave pool at this
South Korean water park, alongside more traditional attractions such as
hot spring pools.
Exhausted visitors can power nap in one of the water park's sleeping
rooms, which have purified air and beds carved from energy-boosting
jade.

Watercube Waterpark (Beijing)
All of the rides at Watercube Waterpark were designed overseas and
shipped in.
Highlights include the funnel-shaped Tornado ride, Aqualoop slide and
Bulletbowl, where riders shoot down an enclosed slide into a huge bowl.
Visitors should keep an eye out for the enormous jellyfish and clouds
of bubbles suspended from the ceiling.

Tropical Islands (Krausnick, Germany)
Housed inside the largest free-standing hall in the world -- the
structure was originally built as a hangar for dirigibles -- Tropical
Islands can accommodate 6,000 visitors a day and has one of the world's
largest indoor pools, measuring 656 feet (200 meters) in length.
Away from the water, there's a rainforest with 50,000 plants, a hotel
and a nightclub. It's even possible to go for a balloon ride -- all
without stepping outside.

WaterWorld Waterpark (Ayia Napa, Cyprus)
Foam parties aren't the only way to cool off in Ayia Napa.
The WaterWorld Water Park has a Grecian theme, with lots of pillars and
Trojan horse-shaped monuments.
Poseidon's Wave Pool has Greek ruins, geysers and shipwrecks, the River
Odyssey lazy river has crumbling stone pillars and the vertigo-inducing
Drop to Atlantis shoots riders out of an enormous Roman temple.

Wet 'n Wild (Orlando, Florida)
Visitors are spoiled for choice at Wet 'n Wild.
In addition to various scream-fest water rides, there's a huge
sandcastle-themed children's area (reportedly the largest family water
play area in Florida), a wave pool and lazy river.
One the most popular rides is Disco H20. Passengers on this four-person
tube ride float along to a soundtrack of 1970s hits accompanied by
disco balls and flashing lights.

World Waterpark (Alberta, Canada)
Located inside Alberta's West Edmonton Mall, this is the world's
second-largest indoor water park and has the world's largest indoor
wave pool, with 2.7 million gallons of water.
Attractions include a looping water slide and Blue Thunder, a bungee
jump tower suspended over the wave pool.

Yas Waterworld (Abu Dhabi, UAE)
Opened in 2013, Yas Waterworld has 43 rides and attractions, including
five unique water slides created specially for the park.
These include Dawwama, the world's first hydro-magnetic-powered water
slide (the hydro-magnetic technology offers a longer, smoother ride,
according to the manufacturer) and the Bandit Bomber, a 1,804-foot-long
(550-meter) water coaster.
Visitors can hang ten on the world's largest FlowBarrel surf simulator,
or take a spin on Liwa Loop -- the Middle East's only looping water
slide.
