A nature route dedicated to the knowledge of medicinal plants, their properties and their most frequent uses. It passes through the valley of Mola, which has a great variety of medicinal plants, and, throughout the entire route, up to sixty different species can be found. In the past, this territory was visited by the valley's trementinaires women, which collected the necessary plants to prepare the remedies that were sold throughout Catalonia. The route starts at the Center of Flora of the Cadí-Moixeró Park in Tuixent and arrives at the Planells de Sastró, where there is a picnic area and the option to take a tour of the arboretum.
