Summiting at 830 meters, Serra do Arestal is part of the Gralheira massif
The Arestal mountain range is part of the Gralheira massif and reaches 830 meters at the summit. Here the Mau, Gresso and Arões rivers stand out, and on their way to reach the Vouga, surpass great gaps originating numerous waterfalls. The waterfall of Cabreia (T2) is one of the most beautiful and well-known, but others such as the waterfall of Gresso (T4), Agualva (T6) and Poço de Grade (T7) are well within reach. On its slopes, megalithic monuments such as the Anta da Cerqueira (T5), and rock engravings in the Forno dos Mouros – Moors Furnace (T3) and Outeiro dos Riscos (T9) mark the ancestral presence of man, revealing great ingenuity and art.
