Puno is the base for Lake Titicaca, and the lake breaks down into three separate visits: the Uros floating islands close to shore, Taquile further out on the water, and the Sillustani burial towers on a different route entirely. The planning question is which combination fits the days you actually have.
The Uros floating islands are close to Puno and work well as a half day. Taquile sits much further out, so adding it turns the visit into a full day on the water. If your time in Puno is limited, decide which one matters more instead of trying to fit both into a rushed schedule.
The Sillustani burial towers are reached by road, not by boat, and sit on the opposite side of Puno from the lake islands. Treat it as its own half day rather than something to squeeze in after Uros or Taquile. [CONFIRMAR: horario, operador y precio del circuito Sillustani].
She checks how many days you actually have in Puno, whether altitude is still a concern after Cusco, and which combination of Uros, Taquile and Sillustani fits without turning the visit into a rushed checklist.
