Druid can get into any of the locked zones

[jokemasterxxx]

You can climb any of the mountains around the locked zones as a druid and get into the zones by spawning the treants you get through the talents on the mountains and then jumping to them its a gr8 tool for jumping around

Pretty much a repost since you aren't giving us any new information. It's pretty self explanatory that you can use the treants to climb cliffs and mountains there.
Also, you can just TP to graveyard, run through the door(s) with your spirit, and then ressurrect on the other side.
