You can find tickes from four U.S. dollars (Approx 12 new soles.) To about 45 dollars, The good thing about Peru is that if you want to travel very comfortable, with buses that offer food on board, with very comfortable seats and direct, ie no stops, except in the places required, is possible. There are buses for every type of economy. But on this route from Cusco to Puno, I always recommend taking buses and Tour Peru, which cost the ticket can cost around $ 15 (40.00 soles), not a luxury service, but it’s worth. Well in this case, there are people who recommend other companies, but some had bad experiences and this makes widespread, in my case, I travel frequently from Cusco to Puno or vice versa, and definitely recommend, Tour Peru.
If you are in Puno, can not fail to visit the floating island of Uros, likewise the Amantani and Taquile Island are places that are frequented by people around the world, and really worth seeing and sharing experiences with the locals. The excursions to the islands leave every day, and there are travel companies that offer them in Puno, or in other cities like Cusco, Arequipa, etc. A Puno can be reached in several ways, by plane, by train (to and from Cusco) and buses, if your goal after visiting this city, Arequipa, there are buses that leave in the morning and evening, and Travel time is about 5 hours and the cost of tickets ranges from 20 to 90 soles. I must clarify that in Peru, there are (for buses) equal rates, rates vary according to the law of supply and demand. Puno held every February 2 its festivities, is undoubtedly the feast of the patron saint of this city, the Virgin of Candelaria. Hundreds of dancers out into the streets to dance, this event is undoubtedly the most anticipated and coincides with the carnivals. Awaits Puno, Puno mute witness to great deeds and deeds, land of intellectuals, artists, good people, tends a bouquet of flowers to welcome you. It is without doubt the place to be able to experience the feeling of being in one of the highest cities on the globe.
