The gateway to the lake (on the Peruvian side) is Puno, considered to be Peru's folklore center.
In fact, they celebrate here more than 300 dances annually. Hardly a day will goes by without a dance to celebrate something.
If you're on the Bolivian side, La Paz - Bolivia's capital - for instance, there are buses departing from the Cementerio district to Copacabana. It's a 3/4 hour ride or 92 miles (148km) distance.
Copacabana is the biggest town on the lake, the ideal place to establish your base camp while exploring Titicaca, surrounding Inca ruins and to do some trekking. Check lake Titicaca map here.
Virgin of Candelaria's celebration and the Diablada (Devil dance) is just fantastic, with a profusion of incredible (and costly) masks, sumptuous costumes and ornamentation.
Diablada was born with the legend of some miners trapped in the collapse of a mine in Bolivia. They saw an army of demons that took them to hell, but they commended to the Virgin and were rescued.
On lake Titicaca you have several interesting and unique places to travel to...
The floating islands of the Uros people:
Uros people live over 40 floating reeds islands maintained by continually adding fresh reeds to the top as the bottom rots away.
They fled onto the lake about 500 years ago, trying to escape Inca and Collas tribes.
An estimated number of 400 Uros people are part of this floating community. They live in reed huts and travel in reed boats - built upon the same craftsmanship as centuries ago
Located about 4 hours by boat from Puno, it's a place with no roads, no cars, electricity or hotels.
Just beautiful landscapes and archaeological ruins. You could spend the night staying with locals or camp on the far side of the island.
With an outstanding textile industry, Taquile it's been proclaimed in 2005 a new Oral and Intangible Heritage of Humanity by UNESCO
The island of the Kantuta flower.
It has important archaeological remains from the Inca and Tiwanaku's cultures on top of its main mountain peaks: Pachatata (Father Earth) and Pachamama (Mother Earth).
Here also you'll be invited to share their housing and food as the local population - mainly Aymaras - are very friendly and welcoming.
Bring some goods as a present with you.
To get there just get a craft from Puno
