The Sanguinho circuit leaves Faial da Terra to explore a valley where water, woodland and former settlement meet within 4.6 kilometres. The initial climb follows the stream among orchards and damp vegetation. Beyond a bridge, the path enters a more enclosed corridor, with running water and forest shade marking the approach towards Salto do Prego.
A signed branch leads to the waterfall, which drops into a pool enclosed by green walls. The main route also meets PR11SMI, a separate trail, before turning back towards Sanguinho. This small settlement developed on a roadless slope and retains houses, walls and cultivated parcels that recall a rural life dependent on footpaths. Its name is associated with the endemic buckthorn found in the surrounding vegetation.
The final section descends to Faial da Terra on a steep old stone lane, opening views across the village and valley orchards. Rated medium and taking about two hours, the loop combines the immediate appeal of a waterfall with a deeper account of mobility and rural abandonment. Visitors should respect both the stream habitat and the properties and buildings at Sanguinho, which are not an unused backdrop.
