Downloading audio walking tours

You need to acquire the Rick Steves audio Europe app from the apple app store. Then when you've loaded the app, click on "Find Tours & Interviews", then "Greece". It lists talks and walking tours. The walking tours have a little walking figure to the left of the description. I'm seeing the following:
Athens-Acropolis
Athens-City Walk
Athens-Ancient Agora
Athens-National Archaeological Museum

When you click on each one, you will see a gold label that says "Download"

It appears that for Greece, that is the extent of the available walking tours. Sometimes the guidebook has walking tours that are not available as audio tours. We've used the audio tours, especially for Italy, and they've worked well. Sometimes it helps to have a paper copy of the walking tour map from the guide.

And, thank you, because I've now downloaded the ones for Greece that I want!

Much appreciated. Thanks a million.
