Ascents and descents mark this route which starts in La Esperanza, in El Rosario, a municipality situated in the southern face of the extreme north along the backbone of Tenerife. After a short stretch of road, continue along the forest track of Los Ovejeros, a continuous climb to Las Laguneras, the last chance to have something to eat on this route. A well-surfaced steep path, with its bird’s eye view of the Güimar valley, leads to the next mountain pass, the Izaña Observatory, at an altitude of 2,300 metres and a 38 kilometre road cycle.
