At over 3,500m, La Paz is the highest capital city in the world. It is a glittering mosaic of tin, slate and tile roofs, interspersed with a line of skyscrapers that march down the valley. Beyond, keeping an eye on it all, is the colossal snow-capped Mount Illimani. This busy, commercial city has a 60% indigenous population; women dress in voluminous multi-coloured skirts, bowler hats and have centre-partings, as decreed by the Spanish monarch 3 centuries ago.
There is a guided walking tour, and 3 nights in the city gives you plenty of opportunity to explore the colonial centre around Plaza Murillo. There is also time for an optional visit to the ruins of Tiwanaku. You travel out of La Paz and across the bleak, tawny earth of the altiplano, past glimmering lakes and herds of haughty alpacas. These pre-Columbian ruins are considered to be some of the most important on the continent, and the massive gateways and imposing walls are redolent of bygone glory.
Alternatively you may like to venture out of town to Chacaltaya, once the world's highest ski resort. From a vertiginous wooden chalet house there are views over 3 countries, and the waters of Lake Titicaca twinkle in the distance.
