An early morning start of the day will find you, and 10–20 others, at the Puno [1] port boarding a double-deck motorboat and throwing on a life jacket. In an hour, on the typical tour, you’ll be at the Islas Uros [2]. From there, it is another 2–3 hours on to the Islas Amantaní and Taquile [3].
The motorboat’s enclosed first floor is often the DVD room, where educational films about the lake and its cultures are shown. The second floor is an open-air deck for sightseeing. Tours can be arranged as day trips or overnights. Some travel agencies now have high-speed boats, which greatly reduce travel time.
