La Geria is an interior part of Lanzarote, which is less touristic than the coast. It is interesting to travel it because it still remains very traditional. With some luck you will be able to go in the summer to the town’s festivities, with traditional dance and music from the Canary Islands.
Besides this, La Geria is a region that is dedicated to agriculture; they cultivate the vine, to make wine, and also potato and basically anything that doesn’t need too much water or to grow too high. The reason for these limitations is that the ground of the island is quite poor, it’s volcanic, and there is a lot of wind as well, that prevents the cultivation of trees and plants that need to grow high. This is why potato is a perfect option. To preserve water, they put volcanic charcoal in the ground, it is quite porous, and so it preserves water in its pores, preventing the evaporation.
