On this excursion we'll visit the Teide, a volcano which is Spain's highest mountain (3718 meter from sea level) and Loro Parque, a zoo where you can enjoy orca, dolphin and sea lion shows amongst many other things.
You can get to Tenerife by boat or plane and it's easy to go there for just one day from Gran Canaria. Tenerife is a neighbouring island, to the West, at only 60 kilometers from Gran Canaria.
