How to create a link to a category from within a post

I have a menu item that only displays a specific category. From within that category, each post, I want to include a link to take the user back to the actual category page. WordPress doesn’t seem to have this as an option when inserting a link to the post.

How would I code that?

I’ve tried the following based on what I dug up from the Codex:

Return to main Maps Page
Return to Maps Page

The first gives me a “not found” error in Chrome.
The second take me to the same page the link is on.

The category “maps” is what shows up in the URL when use the category link and cat=19 is based on the category WordPress gave me, so I’m certain both are right.

Unfortunately, the site is not live yet. I’ve got the theme built and looking good, only needs a few tweaks before I upload it. I’m trying to get most of the content input before doing so, so that once it’s up and running, all of the content of the old site will be available from the start.

Any assistance would be helpful
