Board a boat from Copacabana and spend a full day exploring Isla del Sol's Inca steps, fountain springs, and the village of Yumani. This guided tour pairs cultural history with high-altitude lakeside hiking and includes lunch and round-trip transfers.
You step off the minivan into a wind that carries a high, crystalline light—the kind that only exists above 3,800 meters. Copacabana's shore spreads out beneath the mountains, and Lake Titicaca pulls at the world like a slow, deliberate tide. The boat engine coughs to life and you feel the lake's surface take you, carrying you toward Sun Island, where stone stairways and small adobe houses hover between sky and water.

Spend a day in La Paz or Copacabana to adjust to the altitude; move slowly on the island's stone steps to avoid breathlessness.
Bring a 1L water bottle and high-energy snacks—the sun is strong and there are long stretches without services.
The Inca Steps and ruins are uneven and often slippery from windblown dust; closed-toe hiking shoes improve stability.
Small vendors in Yumani prefer bolivianos for crafts and tips; ATMs are not available on the island.
Isla del Sol was an important ritual center for pre-Incan civilizations and later incorporated into Inca origin myths; terraces and stairways reflect centuries of agricultural and ceremonial use.
Lake Titicaca faces pressures from pollution and invasive species; support local guides and vendors, carry out trash, and avoid single-use plastics to reduce impact.
Wind and sun combine on the lake; a lightweight windproof layer keeps you warm and comfortable.
Good traction is necessary for rocky paths and the Inca Steps.
High-altitude sun exposure is intense even on cold days.

Staying hydrated helps prevent altitude symptoms during the walk.
