Day 5: Our entire stay in Banos was marked by Volcán Tungurahua, which went off every half hour or so. Not only could you hear each eruption, some of them shook our hostel. On the clearest day, we took a taxi up to the power lines opposite the volcano for a better look. A video of one of the blasts follows the pictures and volume would help. Later in the day, we boarded a bus for Puyo, a jungle town deemed the "gateway to the Amazon." We found a monkey rescue center and spent several incredulous hours with the monkeys, who climbed and played all over us.
