how to get there: Go to magic book(not ancients), click on the teleporting spell that says `skillz` Once you teleport there look behind the banks, you should see trees.
Assuming you already have the nessesary axe to start, start cutting the regular tree.
After every full inventory just go bank and come back. Cut the regualr tree to 99, it is the fastest way!!!
But just incase you want to cut any other trees, here are the requirements:
Trees: 1
Oak: 15
Willow: 30
Maple: 45
Yew: 60
Magic: 75
Hope this helped!!!!
