Hop right into a moto-taxi and when they do not know 'Tambopata Hostel', or 'avenida 26 de deciembre', just request the Plaza de Armas (major town sq.); carry on past the main sq. on the proper hand aspect, and on reaching the best corner talk to the driver to turn correct (derecha) and continue as much as the last street (avenida 26 de deciembre),
