Lake Titicaca and Isla del Sol: Visitor and Heritage Guide

Lake Titicaca lies at about 3,810 meters on the border between Bolivia and Peru, and it is large enough to have weather of its own and cold enough to be startling to swim in. The Bolivian side is reached from La Paz in a few hours, by a road that crosses the lake itself on a vehicle ferry at the Strait of Tiquina.

Why the lake matters

In Andean tradition this is where the sun was born. The account recorded of Inca origin has Manco Capac and Mama Ocllo emerging from the lake to found Cusco, and Isla del Sol, the island of the sun, is the place that tradition names. The Inca built on the island, and the ruins there, including the Chincana complex at the northern end and the stone stairway and spring at Yumani in the south, are the visible part of it.

The lake was a center long before the Inca. The Tiwanaku culture, whose ceremonial and political capital sits inland from the southern shore, reached its height between roughly 500 and 900 AD and exercised influence across the southern Andes. Tiwanaku was inscribed on the World Heritage List in 2000 and it is close enough to combine with the lake in a single trip. Seeing them in that order, Tiwanaku and then the lake, puts the Inca material in its proper sequence rather than treating it as the beginning.

Isla del Sol today

The island is inhabited, farmed in terraces that are centuries old, and organized into communities that manage their own parts of it. There are no cars. Getting about means walking, and the walking is uphill at nearly four thousand meters, which is a good deal harder than the distances suggest.

Access arrangements between the island communities have changed over the years and have at times restricted movement between the north and the south of the island. Ask locally, in Copacabana or at the jetty, what the current position is rather than relying on an itinerary written a year ago.

Staying a night rather than making a day trip is the difference between seeing the island and being on it. Accommodation is simple, heating is limited, and the night sky at that elevation is worth staying up for.

Copacabana

The lakeside town of Copacabana is the jumping off point and a serious pilgrimage site in its own right. The basilica holds the sixteenth century Virgen de la Candelaria, carved by an Indigenous sculptor, and the tradition of blessing vehicles outside it happens daily. Copacabana fills completely at its main feast in early February, so check the date before you fix yours. The festivals guide has the calendar.

Practicalities

• It is high. The lake sits above 3,800 meters and the island walking is steep. Give yourself acclimatization time in La Paz or lower first, and read the travel safety guide.
• The sun is fierce off the water and the wind is cold. Both, at once, all day.
• Bring cash. There is very little on the island that takes a card, and the money guide explains why small notes matter.
• The ferry at the Strait of Tiquina takes vehicles and passengers separately, and it stops in bad weather.
• These are working communities and not an exhibit. Ask before photographing people, and expect a fiesta to be for the community rather than for visitors. The culture and etiquette guide covers this properly.
