A favourite among children, this worthwhile museum is dedicated to the balsa raft Kon-Tiki, which Norwegian explorer Thor Heyerdahl sailed from Peru to Polynesia in 1947. The museum also displays the totora-reed boat Ra II, built by Aymara people on the Bolivian island of Suriqui in Lake Titicaca. Heyerdahl used it to cross the Atlantic in 1970.
