Los Gigantes
Tenerife still boasts some places of great natural beauty which are almost completely off-the-radar, such as the forgotten village of Batan. But most areas of potential touristic interest have long since been "discovered". Many of these are still must-see despite the crowds, like the Roques de Garcia. But some of them are like Los Gigantes: over-run, obnoxious places you'd do well to avoid.
