Cactualdea breaks all the rules of successful theme parks. It doesn't have any rides or spectacular animals and is about as far away from the resorts as you can get. However, with one of the world's biggest collections of spectacular cactus, it's well worth the trip to La Aldea town in west Gran Canaria.

At seven euros per adult and four euros for kids, it's good value for money. You can't miss it in La Aldea: Just turn off by the giant cactus sculpture.
