These two countries are very easy to combine in a holiday as the Bolivian border is easily accessible and straightforward. With just twelve days you can visit both countries, the mix could go this way :
Day 01 : Lima
Day 02 : Lima : Half day tour of Historical Downtown Lima with the afternoon free to explore and in the evening dine out and enjoy the Peruvian Cuisine.
Day 03 : Lima / Cusco / Sacred Valley : Fly to Cusco and on arrival yes enjoy a City Tour and the Surrounding Ruins, but maybe you would prefer to stay in the Sacred Valley to avoid the high altitude as Cusco is more then three thousand meters above sea level. If you do not feel it’s a problem and prefer to overnight in the Inca capital, then why not, plenty of people do.
Day 04 : Sacred Valley : Enjoy a full day tour of the Valley, visit places such as Pisac Market, Ollantatambo and if you are coming from Cusco, this tour can easily be done and then you can overnight in the Sacred Valley.
Day 05 : Sacred Valley / Machu Picchu / Cusco : Take the train in the morning and enjoy a full day tour of the Sanctuary, after the tour plenty of time to relax on your own and take in the splendour, before returning by train to Cusco, where you will overnight, again you will have a whole evening to explore this mysterious and magical place.
Day 06 : Cusco / Puno : You can take the bus, which is very comfortable and the road is nicely tarmacked or the train, which is equally good and probably more relaxing, either way it’s a full day.
Day 07 : Puno: No trip here is complete without a visit to the floating Islands of Uros and the Island of Taquila, all by boat and is a full day.
Day 08 : Puno / La Paz ( Bolivia ) : Here we can take two routes, overland by regular bus, or by Catamaran from Copacabana visiting Sun Island, both are in my opinion enjoyable.
Day 09 : La Paz: Enjoy a City Tour, this place is spectacular, it’s the highest seat of Government in the world, over three thousand meters depending on where you stay, as its built into a Canyon, surrounded by the Royal Range ( The Andes ) and snow capped. Did you know, it has the highest Ski Slope in the world and most number of Coup d’etats in the world. An evening dinner on top of one of the multi story buildings is well worth doing and on a clear night you will have the views of the mountains in front of you.
Day 10 : La Paz : Visit the ancient ruins of Tiwanaku, regarded as the cradle of the American Civilisation.
Day 11 : La Paz / Home : Fly home or if you have more time, then visit the Bolivian Salt Lakes, you will need at least three days in my opinion.
