Street art. As of Oct 7, 2014 usually there are some awesome Avenue art south from the plaza de arma. I noticed a number of them all over tambopata Hostel, though the are spaced out in that area. Some inquiring and browsing is necessary. Getting them is a fun time https://buseats.com/puerto-maldonado-airport-your-gateway-to-the-amazons-wonders/v
