A partial rail service serving the Unesco World Heritage site has resumed, as have flights from nearby Cusco airport.
The political situation in the country remains volatile, though, the Foreign Office has warned. Several news wires report there being around 5,000 tourists stuck in Cusco after protesters targeted the airport.
Protests are continuing in capital Lima, as well as in other major Peruvian cities such as Arequipa and Cusco, according to the FCDO.
