If you arrive in Cusco with the intention of hopping on the train to Machu Picchu the next morning, you'll probably only have time to take a stroll though the Plaza de Armas and visit Qorikancha (Temple of the Sun) and the Catedral. However, we recommend spending at least two days in Cusco before venturing off to Machu Picchu, giving yourself time to acclimate to the altitude and get to know this city of terra-cotta roofs and cobblestone streets.
Cusco takes its newest role as tourist favorite in stride, and absorbs thousands of travelers with an ample supply of lodgings, restaurants, and services. That such a polished infrastructure exists in such a remote, high-elevation locale is a pleasant surprise.
A special note: in an effort to protect historical artifacts from light, guards in Cusco's museums and churches are notoriously watchful about prohibiting all types of photography, flash or not, still or video, within their confines. The exception is the Qorikancha, which allows limited photography, but not of the fragile Cusqueña school paintings on its walls. Also, guide services in English are included with the admission price at many Cusco sights. Tipping is not expected.
It's an easy train ride from Cusco to Machu Picchu, but for exploring the Sacred Valley, a car is the best option. Those who don't want to drive can take any of the frequent buses that run between Cusco and the Sacred Valley communities. In fact, the entire area, though still very rural, is well served by good roads and public transportation. The vehicular tourist route ends at Ollantaytambo, beyond which your options are to travel by rail -- most visitors board the train in Cusco, however -- or on foot along the famed Inca Trail to reach the remains of Machu Picchu.
