"To unlock the other locations on the Balloon Transportation Network, you will have to complete puzzles similar to the ones in the quest. Each puzzle has a unique setting with numerous methods to solve it, so simply do not run out of sandbags or logs. You can go to:

 

 

 

* Crafting Guild - Requires 10 Oak Logs

 

* Varrock - Requires 10 Willow Logs

 

* Castle Wars - Requires 10 Yew Logs

 

* Grand Tree - Requires 3 Magic Logs"

 

 

 

Can anybody tell me the steps i have to do like in the quest guide for each region?

I used a guide in the PMG I can't find at the moment, but you can use Runescape Wikia.

Thx a lot!
