Sintra to Obidos: Portugal's Ultimate Road Trip Guide

The 80-kilometer drive from Sintra to Obidos via the A8 motorway takes about 1 hour, but the real journey unfolds along the scenic N247 and N115 roads that trace the Atlantic coast and the foothills of the Serra de Montejunto. This route passes through medieval villages, vineyards, and windswept beaches, offering a microcosm of Portuguese heritage. The stretch is part of the historic Estrada da Costa, once used by pilgrims traveling between the Sintra Mountains and the fortified town of Óbidos.
