What to expect
The stripes are the subject of many photographs, but your day also includes the approach and return walk. Ask about more than time at the viewpoint. Have the provider describe the whole route, including where you can decide not to continue.
How it fits into a journey
Give Vinicunca a separate day and keep the following programme flexible. Confirm the approach and weather shortly before departure; an old reopening notice is not a guarantee for the day.
