Gran Canaria's Wild West theme park is the perfect place to spend a day with the kids, and has a fully-stocked saloon for the adults.

If you drive around Gran Canaria, a stop at Cactualdea cactus park is well worth the stop. 

Palmitos Park is set in twenty hectares of a palm-filled valley just inland from Maspalomas and Playa del Ingles. It started as an exotic bird park but now has everything from komodo dragons to dolphins. Palmitos is a great day out for adults and kids and even when it's full there's plenty of room for everyone.
