About 1,000 men, women and children set off in August on a 500km (310-mile) march from the Amazon town of Trinidad to La Paz in the high Andes.
The marchers, many of them from the humid lowlands and unused to the high altitude and cold of the Andes, made a triumphal entry into La Paz on Wednesday, being greeted as heroes as they entered the city, accompanied by groups of workers and students.
