finshed dragonspire but need to get back to Ishad N'ha

Just completed the dragonspire and I want to get back to Ishad N'ha. Is the only way back to Ishad N'ha through the dragonspire? I tried that, work my way back through the dragonspire to the entrance and throw the switch but it never loads me back outside the dragonspire. It loads but always loads me inside the dragonspire, not outside.
Just want to finish a few quests in Ishad

If your crew can take a hard landing.. there's an easy way to do this... when you exit from the dragons room.. go out to the ledge.. if you turn left and hug the ledge.. you can walk all the way down to the side that Brimloch Roon is on... BUT, if you drop off the cliff (you might be able to climb down, depending on your crew) BEFORE the tree line, you will land on the side of Ishad Hna~ also, if you have the CALL TO HOME spell.. it will automatically take you back to the last town you were in~ (without risking the fall)~

Good luck,
