/loc is your friend if you get lost in a zone to get your coordinates.
You are going to need to get SOW so you can run fast, an invis if you can get it then and a port to West Karana (WK) from a Wizard or a port to North Karana (NK) from a Druid.
From WK, Then run to Qeynos Hills (QH), Black Burrow (BB) and then Everfrost to Halas
From NK, run to WK, QH, BB, then Evenfrost to Halas.
It is a long run and dangerous road to run as a level 3, I would just stay and in the Freeport Area and level up to level 5 - 7 before attempting.
Remember once you get back to Halas/Everfrost, you might want to see if someone is there that can bind you. That way if you die, you are not in Freeport again....... that would suck.
