As with many hiking trails in Portugal, the path starts very wide and is easily accessible. As one continues walking, it gradually becomes narrower, steeper and more rocky. Accompanied by all kinds of butterflies in different colours, you will encounter many old windmills. At the end of the trail, you automatically arrive at the Ecoparque Sensorial da Pia do Urso. Here children can discover all kinds of natural science in a green environment; science and nature inextricably linked.
