The municipality of Fasnia is located in the southeast of Tenerife, stretching from shore to peak.
The climate in most of this municipality is arid, but pine forests grow on the peaks due to the moisture brought by the trade winds.
The city grows grapes, flowers, potatoes and tomatoes. On the coast are the rock of La Ondoura, declared a place of special scientific interest, and Los Roques, a place of incredible beauty.
