Isla Magica (Magic Island) is a theme park with a twist. It's all based around 16th century Spain, with the emphasis on exploration. Lots of galleons, pirates, jungles and lots of adventure. It's big - the park is set on the site of the 1992 Expo and split into a number of different themed sections.
In the Amazonia section you can get the heart pumping with the famous El Jaguar roller coaster and a waterfall ride. In the Gateway to the Americas section there's a 'water coaster' and a Navigator's school. There's also a Mayan world, a section for the little ones, cinemas and virtual shows, and a planetarium.
Isla Magica is separated from the city by a bridge, but it's easy to get there on the C2 bus.
