Because of the altitude, you are likely to find that you feel a little lightheaded when you first arrive in Cusco.
Take it easy, drink plenty of water and you should be fine within a day or so.
The center of Cusco is quite small and possible to explore on foot.
It has an abundance of good artisan markets, local ruins, internet cafes, bars, restaurants & nightclubs.
The Plaza de Armas is the main square with Avenida El Sol the main street, Triunfo to the right of the Cathedral is the most interesting street leading up towards the San Blas Plaza.
Included with Pura Aventura holidays to Peru is the combined entry ticket to most of the main sites in and around the city.
Called ?Boleto Turistico Unificado? (Visitors? Ticket).
On the back of the ticket is a map of the centre of Cusco with the main sites shown. You will visit many of these as part of a normal Pura led visit, including the temple at Quricancha.
Of the sites to which it permits entry, the following are highly recommended:
The Cathedral in the Plaza de Armas with impressive silver altar. Sacsayhuaman, impressive Inca ruins on the hill high above the town, half hour walk up hill from the plaza or take a taxi (3-4 soles).
Surrounding Cusco are the archaeological sites of Qenqo, Tambomachay (Inca fountains) Puca-Pucara (the Red Fortress) further on from Sacsayhuaman which can be hiked/ridden to or take a taxi (remember to arrange your return).
Also included is entrance to the ruins above the market town of Pisac, Ollantaytambo and Tipon.
