PortAventura theme park in Spain is to relaunch its Caribbean-themed aquatic park following a 11.6m euro (£10m, UD$15.6m) extension project, which features the tallest toboggan in Europe.

The Costa Caribe Aquatic Park project has seen the addition of 14,000 sq m (150,695 sq ft) of new facilities, giving the park a total surface of 50,000sq m (538,196sq ft).

Located in Salou near Barcelona, the park is slated to open in May – ahead of the European summer season - featuring three new toboggan rides.

The tallest is the 333.7 ft (31m) free drop toboggan with a drop speed of six meters per second.

A 215ft (20m) high multi bump Toboggan will be a more moderate experience with a rolling trip and two fast slope changes.

Another area of the park will be dedicated to a six-lane toboggan with a range of slope changes and water jumps.

The new children's pool will have two depth levels: 50 cm and 30 cm. A highlight is to be the pirate ship full of Sesame Street's characters with four toboggans. There will also be a Splash Pad, a small play area with interactive water jets.

The tropical adult pool, which is attached to the children's pool, will be placed at a different level, so a waterfall is created in the children's pool. Waterbeds and various water effects including a waterfall will feature at the adult's pool.

The park will also have large green areas with more than 50 plant's species and palms.

With this latest extension, the park will house 16 attractions and toboggans, 8,500sq m (91,493sq ft) of water's sheets, and 5,000sq m (53,820sq ft) of green areas.
