Hike with the BSGS in to the clouds on the PR1 path.down from the Pico do Areeiro (1818 m.). Madeira is a volcanic island but this area is described as resulting from water erosion, it is not thought to be a volcanic caldera. We'd hoped to see from above the huge Paredão valley systems that we had viewed earlier from the Miradouro da Eira do Serrado (1095 m.) but the clouds had intensified. Nonetheless, we hiked down nearly 300 m. altitude to cross a narrow ridge path not much wider than Striding Edge on Helvellyn or Crib Goch on Snowdon.
