Players can travel to the Grand Tree via the gnome glider on the 3rd floor[UK]4th floor[US], or they can use seed pods from the Gnome Restaurant minigame to transport instantly to the Grand Tree. You may also use the royal seed pod after completion of Monkey Madness II. Just south of the tree itself is a spirit tree, and a landing spot for the Balloon Transport System. For those who don't have access to gnome glider or seed pods, you can also teleport to the Outpost using a necklace of passage and head north.
Players can find King Narnode Shareen on the ground floor[UK]1st floor[US]. Players can speak to him to begin (and later end) the Monkey Madness I quest. There is also a trapdoor that leads to the Grand Tree Tunnels (and a mine), though players must have completed The Grand Tree in order to use it.
The 3rd floor[UK]4th floor[US] contains of a small jail that Glough locks the player in during The Grand Tree quest and a Gnome glider which can be used to travel to various places in Gielinor.
