So a interesting thing i found, it's quite simple but if you're going to be leveling Archaeology on a Druid get the Glyph One With Nature which makes you teleport to a random place in nature such as a forest etc, so say your dig site is in Ashenvale and you're in Tanaris keep using that spell and you will eventually end up near or in Ashenvale. This may take a few teleports but I honestly found it much faster than finding a mage port/flying everywhere.
