This mountain, with its height of about 2,350 meters, is part of the Güímar mountain crown and is the result of the succession of eruptions of various volcanic cones for thousands of years.

Izaña plays a very important role in terms of the seasons, because in the cold winters it is covered with snow and in autumn and spring, the sun is behind it. As the temperatures and general microclimate of this mountain are too severe for many plants, there is little vegetation here, but in the shallower areas, the Canary Gorse, a very fragrant endemic plant, grows.

Due to its meteorological properties, Izaña also hosts one of the AEMET stations.
