Today we went to the Pico de Bandama. It's the highest point around the crater of the Bandama volcano. From there I could look over the northern and eastern coast of the island: see ing the capital Las Palmas, the coastline, the vineyards we drove though to get here to the north-west and the oldest golf club of Spain (founded by the British in the 19th century) to the south-west. (views are: north/east/south-east/north-west/south-west)
On the way back down from the top I took a peek into the crater. It's about 1000m wide and 200m deep. If you look closely you can see a farmhouse at the bottom. Warm air is rising along the sides. It feels somewhat dangerous.
