Trollheim

Trollheim is the tallest mountain in Old School RuneScape. It is located right to the east of the entrance to the Troll Stronghold.

Travel[]

All methods of travelling to Trollheim require at least partial completion of the Troll Stronghold quest.

The Trollheim Teleport teleports the caster to the top of Trollheim, just outside of Eadgar's cave. Players must have a Magic level of 61, and completed Eadgar's Ruse to use this spell.
A Trollheim tablet can also be created using a scroll of redirection to a normal house tablet after Eadgar's Ruse.
From Burthorpe, travel north past the Death Plateau and through the arena (need climbing boots).
Travel through the fairy ring system, using the combination ajr (Kandarin), and travel through the Troll Stronghold, which requires climbing boots.
This route is used to reach the God Wars Dungeon. It is recommended to use the Protect from Missiles prayer near the level 68 Troll rock throwers, because they are aggressive to players.

Trollheim has at least 4 Agility shortcuts, which vary in required Agility levels from 41-64 to be climbed.

There are some level 68 Troll rock throwers near the bottom of the mountain. Use of Protect from Missiles to get by them without damage is advised.
Mad Eadgar resides in his cave at the top of the mountain.

Quests involving trolls are also involved with Trollheim:

Trollheim is a possible reference to the Norwegian valley, Trollheimen. But since 'heim' means 'home' in Norwegian, Trollhome seems more likely.
Every troll, or cities made by trolls have the names dialected into Norwegian. This is likely because they live at the top of Gielinor and Norway is at the top of Europe, and also because trolls play a big part in Norwegian folklore.
Some of the rocks (not the ones you can climb) have amusing examine texts. One reads "It's a troll! Run! No, wait, it's just a rock" and another one reads "These make great pets."
