To begin a City Tour, find a city with a yellow label in Hybrid view. Tap precisely on the city name and select City Tour. Obviously, it only works in a subset of cities including New York, San Francisco, San Jose, Glasgow (UK), Barcelona, Rome and Paris. Cities that have a tour are indicated by a yellow label, in contrast to the usual white labels.  Subsequently, the option has been spotted in Yosemite’s Maps app. Unsurprisingly, it functions the same as the iOS app.

It seems that City Tours can currently only be accessed from the ‘Hybrid’ view. Screenshots from our previous article show that Apple has at least experimented with labels in the detail views, so perhaps these interactions will appear in the future. The fact that nobody discovered this until today is probably a good indication that more work is needed in future betas to make the process clearer.
