I don't have a link off the top of my head, but if you search for all caches in a state using the hide and seek a cache page, then click on the little blue ribbon at the top of the page and it will re-order the search to show all of the "most favorited" caches in the state.
This link to "Alabama's Most Favorited" should do it.
Of course, this works with any state, but you do need to be a premium member to reorder by favorites, at this point.
