Take a break from the heat and crowds in downtown Rome and set off to explore the lush Castelli Romani countryside just south of the city. Pick up your bike in Rome and then set off with your cycling guide by train to Castel Gandolfo for a scenic bike ride past the Papal Palace and Lake Albano. Discover the charm of Nemi and feast on local specialties during a lunch break (own expense) before the return train trip to Rome.
