Sunsets from the beach are cool. But taking a 4x4 ride into the mountains to watch the sun dip below the horizon? That's an altogether more adventurous experience.

On this guided evening excursion into Portugal's scenic Algarve region, you'll visit natural springs and waterfalls at the village of Alte, before heading into the hills in search of a tranquil spot to watch the main event.

Top tip: pack a couple of cold drinks, and toast to planet Earth as the sun goes down!
