For such a small island, the mountains and the gorges are spectacular. We explored quite a bit of the mountains. Driving through mountain gorges is spectacular.
The other feature worth mentioning are the huge sand dunes. The highest are close to 100 m (330 ft) high.
Plant life is surprisingly varied. There are a lot of endemic trees and other plants on Socotra. The Dragon Blood Trees (Dracaena cinnabari, german: Sokotrischer Drachenbaum, french: Dragonnier de Socotra), the Cucumber Trees (Dendrosicyos socotranus), and the Socotra Desert Rose (Bottle Trees) (Adenium obesum socotranum, german: Wüstenrose, french: Rose du désert) are the most spectacular. The Frankincense Tree (Boswellia elongata), from biblical Frankincense, are also worth mentioning.
Animal life on land is by far not as exciting as plant life. I only saw a few lizards and some land crabs near the shore.
