Flickr has an important collection of photos of Tenerife. We found these pictures far more real than the typical tourist guides photos, as they show the Island of Tenerife from the point of view of tourists and locals without censorship. Clicking the current photo provides the author and sometimes the location.
If you are looking for photos of a specific location or subject like Carnival or beaches check out the following Tenerife photo gallery: Photos of Tenerife
