How to access yaml list / sequence (array to string conversion error)

I’ve written a list in my site.yaml:

— yaml
- “08:00”
- “13:00”
- “16:00”
- “18:30”

I assumed, that the data would be accessible from the twig via

--- twig

similar to json, but I get an error: An exception has been thrown during the rendering of a template (“Array to string conversion”)

So how to access this data?

site.times.monday[0][0] should work
