If you are completing an OSRS quest that involves dwarves, you will need to how to get to Keldagrim. This is because Keldagrim is known in Old School RuneScape as the city of dwarves. The Blast Furnace minigame and the Rat Pits are also here.
There are 3 quests that involve the city of dwarves. These are the Giant Dwarf Quest, Between a Rock quest, and the Forgettable Tale of a Drunken Dwarf quest.
How to Get to Keldagrim: Starting the Giant Dwarf Quest
Any player who wants to go to Keldagrim will first have to start the Giant Dwarf quest. This is an intermediate quest requiring low-level skills for members only. To start the quest, you will need to talk to the Dwarven Boatman. He is located inside the dungeon which is east of Rellekka. (Rellekka is south of Olaf.) He will take you to the city of dwarves, and the quest begins.
One other quest that you can start to get to Keldagrim is Another Slice of H.A.M. You will have to complete this quest to open up the Dorgesh-Kaan-Keldagrim train system. This train system will take you back and forth between Keldagrim and the Dorgesh-Kaan city of cave goblins.
How to Get to Keldagrim: After the Giant Dwarf Quest
Players who have started the Giant Dwarf quest have other options to get to Keldagrim. This includes going to the Grand Exchange. Here, you will be able to find a trapdoor which is located south of the agility shortcut. This trapdoor leads to the Keldagrim mine carts. They will take you close to the Blast Furnace for no charge.
You can also take the mine carts from Ice Mountain at the northwest corner of the Dwarven mines. Also, if you have won the fishing contest at White Wolf Mountain, this is another option. Then you can take the mine carts from the east end of the tunnel located under the mountain. Traveling this way to the city of dwarves will cost you 100-150 coins. Although, if you wear a ring of charos, they will give you a half-price fare.
It is also possible to teleport to the city of dwarves using the fairy ring code d•k•s. This will put you next to the entrance. If you have the enchanted lyre from the Fremennik Trials quest, you can use it to transport to Rellekka. Then you can walk to Keldagrim. You can also teleport to Camelot and then walk.
Blast Furnace Minigame Group Finder
Blast Furnace is also a members-only minigame in Old School RuneScape. Since Blast Furnace is also in Keldagrim, this another way to get there. The Minigame Group Finder can teleport you to the Blast Furnace if people are playing the minigame.
This minigame is considered to be low-danger. However, you must have the skills to be able to teleport here. This includes Smithing level 60, as well as Strength, Agility, and Crafting.
