Islas de las Canarias are a Spanish archipelago in the Atlantic Ocean, 60 miles off the coast of Morocco. The islands are known as the "land of eternal spring", with great year round climbing on basalt. The islands are, from west to east, El Hierro, La Palma, La Gomera, Tenerife, Gran Canaria, Fuerteventura, and Lanzarote. Tenerife is the largest island, and the most popular with European sun seekers. Gran Canaria is the second largest, and like Tenerife, is very popular with the tourists. The islands are rich with history, and culture, which should not be missed. The Canary Islands are not as well know as other sunny spanish climbing destinations, Mallorca, but they should not be missed by someone who is looking for quality climbing in a sunny, warm, beautiful setting.
From mainland Spain, Tenerife, and Gran Canaria are 3-4 hours by airplane. There is a ferry from Cadiz that takes about 24 hours if you feel like a boat ride. A car hire is advisable as the climbing areas are mostly off the public transportation grid.
It seems that the climbing on Tenerife is the most developed, and with a new guidebook being printed this month, the most documented. Although I have never been to Gran Canaria or Lanzarote, I did find information for climbing on those islands. There are ferries, and hydrofoils that connect the islands, with very reasonable prices.
