El Hierro is not just the westernmost island of the Canary Archipelago, but until the discovery of the Americas, it was the westernmost spot of the Old World, as Europeans, at least, used to map the world as they new it. This conjuncture led to the naming of El Hierro as the Meridian Island, since time zones used to be counted west to east starting from El Hierro. Besides this interesting historic reference, tourists should also keep in mind El Hierro is one of the cleanest of all islands, given the authorities have implemented, at least in part, a project of turning El Hierro into a spot completely and exclusively fueled by renewable sources of energy. This project is paralleled, at the archipelago scale, only by the Bioclimatic Village in Tenerife.
The only sea line company linking Gran Canaria to El Hierro is Naviera Armas. Their boats leave from Las Palmas and haul ashore at Valverde.
Binter is the only inter-island flights operator providing services for tourists interested in making a short trip to El Hierro.
Otherwise referred to as Aquasur, Aqualand Maspalomas is the largest water park in Gran Canaria. As the name suggests, it is located in Maspalomas.
Banana Park is located in Maspalomas, and it stands out as a huge banana plantation pegged out by several hundreds of specimens of orange trees.
Both the means and the reasons for making trips from Gran Canaria to Tenerife, the largest island of the archipelago, are solidly reliable and grounded.
