If you scroll back up a couple of sections in the Webalizer report, you will see a section titled 'Top x of x Total URLs'. This is the most popular requested URLs, not necessarily pages but, if you see any of your pages there, those are the top.
In my Webalizer log, the third entry is for
/, which is the site root so it is the most popular page because the two above it are resources loaded by the pages.
Webalizer reports are taken from the access logs directly on your web server so, it can be complicated. GA is a good tip to use in addition since it loads in page and directly logs the request and, will give you information about referrers etc.
