A Scenic Route

Los Llanos del Jable, with El Paso behind The main roads on La Palma form a rough figure 8, with the main east-west road being the LP2 from Santa Cruz to Los Llanos, through the tunnel. But whenever I’ve got time, I like to take the scenic route, the LP203. This winds up through the heather and bayberry forest, past the astronomical viewpoint at Llano de la Venta then pine…
