Get out of the city for one day and enjoy the uncontaminated nature of the Maremma, in southern Tuscany on the Tyrrhenian sea. With the bike + train formula it is easy, cheap and sustainable. Pedal among the sounds and scents of the Mediterranean ecosystem, in the shade of the umbrella pines, between the sea and the lagoon. Dive into the crystal clear sea. Have lunch in Porto Ercole, an ancient fishing port at the foot of a Spanish fortress. End up in the town of Orbetello famous for its traditional lagoon fishing techniques.
