Hi,

You have some alternatives:

1. You can create a list of cities ... but is better to specify each element of the list with H3 or H4 tag

2. You can create a list with cities(links) and make a page with dinamic content you can add the text you need by passing the parameter to other page

3. Search for an image and map on it and add alt or title to each map on image

4. Add div with images pieces of map add ALT and title to images with cities or towns create a small galery
