The Grenwall portal is a portal located in the Gnome Stronghold that leads to a private hunting area. It can only be accessed if the player is holding at least one grenwall quota ticket, obtained from the Big Chinchompa activity, in their inventory.

The hunting area accessed through this portal contains grenwall that can be caught by the player without competition. A ticket is used up each time a trap is checked, limiting the amount of time that may be spent there.
