More likely you're using it wrong. undotree() actually does return a dictionary, not a string. So you can't do this:

:echo "undo tree is: ".undotree()

You should be able to do this, but it won't tell you very much without some heavy-duty parsing:

:echo string(undotree())

That's where the undo plugins come in.

You can try making sure the file is saved in its current state, making sure the undo file is written, then installing one of those plugins and starting a new Vim instance to edit the file. Ignore the swap exists error, you can always quit without saving in the new Vim. Then you should be able to navigate through your undo information more easily.
