Spend a lovely afternoon in Sintra, a fairytale-like hillside town, which was also declared a UNESCO World Heritage Site, just outside Lisbon. This half-day tour includes a guided element, but you'll have two hours of free time to explore on your own. Then, bring your camera to capture a shot of Cabo da Roca, the most westerly point in mainland Europe. On your way to Cascais, a beautiful coastal town with pretty beaches, you will also pass Hell's Mouth (Boca do Inferno), a chasm in the seaside cliffs.
