Close to Quito the extinct Volcano Ilalo at 3194m divides the Tumbaco/Cumbaya Valley from the Los Chillos valley and was a strategic spot for the native Inga (not misspelled) people. They mined obsidian and had agricultural plots here from hundreds of years ago. It was also a 360 degree observation viewpoint.
Now it is a pretty busy local spot used by hikers, bikers and dirtbikers. We accessed from the Tumbaco valley via steeeep dirt roads and rode down the Angamarca trails.
