Isla de Sol – Bolivia
According to legend, Island of the Sun is where the Inca were created and the sun’s birthplace. Catch a ferry, buy tickets from the booths near the pier from Copacabana. It is advisable not to go by local fishing boat – I’ve heard accounts of boat owners stopping at the wrong place and refusing to go any further until tourists pay more money.
Expect to be underwhelmed by the Inca sites – there’s hardly anything there – but the views are amazing.
If you are treking across the island from Cha’llapampa to Yumani expect to pay a toll each time you cross a village’s territory. Make sure that the guy with the tickets hands one over before you give him the money - we spent 10 minutes arguing that one of us had paid. If you are on the day trip watch the time as you may miss the boat home if you are a slow walker.
Unless you are an archeologist or like walking along bleak ridgelines at high altitude and paying extra for it, I would recommend staying for a couple of days at Yumani.
Take your time to explore, absorb the village life and settle in at night to watch the spectacular sunsets.
