Otto's Grotto is an area west of Baxtorian Falls where players can start Barbarian Training. To get here, rub a games necklace and head south-west. Also near here is the entrance to the Ancient Cavern, a large whirpool at the end of a dock. Another way, through the Tree Gnome Stronghold, requires The Grand Tree quest.
There is a barbarian anvil (to make hastae and spears) and several trees of various types. In addition, there are fishing spots close by that contain Leaping fish, which can be cut and used for barbarian potion mixes, as well as offering some of the best Fishing experience in the game. This requires a barbarian rod, which can be found by searching Otto's bed.
If players head due north and then turn west, they will find a shortcut that leads to the Gnome Stronghold.
- Barbarian Training miniquest is started here.
