The Grand Tree includes two of the three banks in Tree Gnome Stronghold, several shops, and a bar and restaurant. The Gnome Restaurant minigame is on second level, and players who have completed The Grand Tree quest can access the Grand Tree Mine. There is an Agility shortcut north-east of the Grand Tree, which can be very useful for players training Barbarian Fishing.
If players use a herring (raw or cooked) with the Grand Tree, they will get the following message: "It can't be done!", referencing the film Monty Python and the Holy Grail.
On 8 February 2010, if a player is standing near the gnome glider on the top floor with the textures feature on, their character will be invisible but will leave a shadow behind, the same goes with the gnome and any summoning familiars, this was fixed later that day.
