An unambitious but pleasant morning stroll starting from El Papiol into the south-western part of the Collserola, checking out the Escletxes de Papiol and joining La Rierada, Collserola's only permanent watercourse. That said, it was suffering from the drought, with the stream disappearing a few hundred metres before reaching the famous little waterfall. HIKERS: PEZ K3 MIX TRANSPORT: R4 train to and from El Papiol / Molins de Rei ROUTE: Linking these two routes: https://senderismeentren.cat/2015/10/26/120/ https://senderismeentren.cat/2015/05/12/106/ HIGHLIGHTS: The town of El Papiol with its castle was surprisingly nice. Some interesting houses on the way, one with three different dogs... A very interesting poop with a blanket of beautifully coloured fungus.
