Paul da Serra's geological trail, closed in 2026. It starts at Bica da Cana (1,588 m at the highest point) and reaches the ER 105 in 4.6 km, about 1:30, between 1,457 and 1,588 m. The whole route shows the evidence of a plateau glacier that covered Paul da Serra, peaking at the Last Glacial Maximum some 25,000 years ago: a shallow glacial valley with a rounded U-shaped profile, a circular hollow scoured under the ice, then the climb onto the eroded top of an old basaltic cinder cone, Fonte do Juncal, born of a Middle Pleistocene eruption (between 1.8 million and 774,000 years ago). From the cone, a panorama over the plateau; on the way down, the Rabaças viewpoint overlooks the head of the Ribeira da Ponta do Sol valley and its moraine deposits, large basalt blocks and columns. The route ends at the Fajã Redondo glacial cirque at Sítio das Pedras, a site of exceptional geological value where the ruins of the pens once used for traditional shearing remain. A plateau without shade.
