The major road from Riobamba to Macas is very controversial since it was built right in the middle of the Sangay National Park, but now that it exists you can take profit of it for an easy visit to the Sangay NP. There are reguler public busses on this road, every 1 or 2 hours. Take a a bus to the Lagunas de Atillo, and than walk the next 12 to 15 km towards Macas. The environment is superb. First the lakes, then you climb (slightly) to the pass, and the first 10 km of the descent are really stunning, cloudforest, waterfalls (If you travel by car, please note there is no parking anywhere along this stretch). Well of course it also means clouds and rain. Then you can board another bus to continue to Macas or return to Riobamba. Further towards Macas, there is a lot of colonization along this road.
