Cruz do Touro rises to 1,231 metres and forms part of the chain of peaks that gives shape to the sweeping mountain landscape between Galicia and Portugal. Like many of the summits of the Xurés, its significance lies not only in the mountain itself, but also in the wider landscape it helps reveal from Olelas: deep valleys unfolding between granite ridges, rocky outcrops emerging from the slopes, and a succession of peaks rising beyond 1,000 metres and stretching towards the Portuguese horizon.

Together, these mountains create a continuous cross-border landscape in which valleys, ridges and summits seem to flow naturally from one side of the border to the other. They also provide particularly valuable habitats for birds of prey such as the golden eagle, griffon vulture and short-toed snake eagle, as well as the occasional cinereous vulture.
