The greenest of the Canary Islands, and very little tourism. Only the two black beach resorts and Fuencaliente have large hotels, so you can enjoy the whole island in relative peace. Car rental is very reasonable from Pluscar, and the roads good, and uncrowded. Add to this a beautiful capital city in Santa Cruz de La Palma, and excellent small museums.
Away from the two / three resorts the food was cheap and delicious, and the small island bananas the best you have tasted. We got there on an inter-island Binter flight from Tenerife, only 30 minutes flight from Tenerife Norte airport.
An island really worth visiting.
