More ways to explore the area's outdoor wonders
You step onto a ridge above the Guadiana, the river threading a green seam between Portugal and Spain. Wind tugs at your jacket as guides clip you into a single, continuous cable: 750 meters of zip line that bridges two countries in one long, airborne stretch. The van ride from Lagos eases you out of the busy Algarve coast and into farmland, then the scent of eucalyptus and cork oak grows stronger as stone houses scatter along the valley.
