Depart from La Paz on a fully guided day-trip that sails on Titicaca Lake and visits Copacabana and Yumani as well as Isla del Sol. Enjoy a tasty lunch and discover the famous Inca Steps and the Inca Fountain. Leave La Paz at around 7 am and after approximately 3 hours you will arrive at Tiquina, the narrowest part of the Lake Titicaca. Cross to the other side by boat and continue the trip on a 30-minute bus ride to the town of Copacabana. Once there, have lunch and then head towards the shore to catch a boat to the Isla del Sol, where you will see the Inca steps and the Inca fountain, also known as the youth fountain.  This Inca fountain represents the 3 pillars of the Aymara Culture, Ama Sua, Ama Llulla, and Ama Quella, which mean, you shall not steal, shall not lie, and shall not be lazy. Afterward, visit the town of Yumani and then start heading back to the port to catch the boat back to Copacabana. Once in Copacabana, explore the church, main square, and the crafts market. By 6 PM you will catch the bus back to La Paz, where you should arrive back in the city by 10 PM.
