I'm planning to go from Cusco (after visiting Machu Picchu) to La Paz in Bolivia. I already know many people do this by bus, but I'm not sure if those buses go straight to La Paz, or if they always stop by Puno.
I'm interested to know since I will be in Puno before going to Cusco, so I would not like to go back to Puno in order to get to La Paz. I would like a non-stop bus going from Cusco to La Paz.
Do you know if such a bus line really exists ?
