Some practical advise for a visit to the Lagunas de Atillo and Laguna Negra out of Riobamba. I organised a car with driver for USD 70.- from a small travel agency that is located right at the entrance of Rayuela Restobar  (probably one of the best and cleanest restaurants in town) in Riobamba. The contact person is Mrs. Maria Del Carmen Baez, and she did it for the next day, so no reservation needed. We drove even a bit down direction Macas, into Morona Santiago province, experiencing a great change of vegetation with  the sudden sighting of palm and banana trees amid tropical temperatures.
