God of War - Mountain Interior puzzle and how to reach The Summit

A walkthrough for the fifth part of the God of War story mission, Inside the Mountain.

The Summit, and the final few chambers of the Mountain Interior are the locations of your next objective in God of War PS4's main story quest Inside the Mountain.

Here on this page, we'll take you through everything you need to know about this section of your quest, including how to solve any puzzles, take down any bosses and find any useful loot along the way. For guides to specific collectibles we also have pages on Valkyrie locations and how to open Hidden Chambers, Lost and Found locations and Faces of Magic locations, too.

This page follows on from God of War - Hraezlyr boss fight.

Mountain Interior puzzle solutions and how to reach The Summit

The final few, upper chambers of the Mountain Interior contain a few chests and goodies, another Nornir rune chest puzzle, and some frosty enemies for you before you reach the mountain's peak.

Head inside after smashing that first wall of red sap by Sindri, and immediately turn right at the first opportunity to find a Legendary chest that can be reached by shooting the red crystal on it with a Shock Arrow.

Continue on to the chamber at the end of the short tunnel and watch out for a new kind of enemy, a Nightmare that can possess Reavers!


Deal with it by stunning the possessed Hel-Reaver, which will remove the Nightmare from it, then focus on the Nightmare in the usual way (ranged attacks) before dealing with the standard Hel-Reaver after. Now, you need to solve a puzzle to continue climbing.

First, turn to the right and shoot the crystal in the red sap that's at head height nearby.


Behind it is a littler chamber that contains the third Cup Artefact of the Bottoms Up set.


Then, go to the wheel near the entrance and get pulling. This will raise the now-freed bucket with a red crystal in it. Pause when it's next to the higher red sap just to the left of the bucket and have Atreus hit it with another Shock Arrow. This will detonate the sap to the left of it and drop the rocks, allowing you to climb up them as a new platform and continue.


Watch out for the new set of Nightmares that spawn, then press on.

You'll find more Nightmares and Hel-Reavers in the corridor ahead, and you'll notice another wall of red sap on your left as you continue - back to this in a moment. For now head to the next chamber just in front of you to tackle three more Hel-Reavers and find another Nornir rune chest on the South-Eastern wall.


There's some red sap above you in the opposite direction, holding up a bridge, plus the red sap you just went past in teh tunnel and, of course, there's a little world tree stump with some red crystal you can pull out and throw just nearby. You know what to do!

First grab the crystal and go back down the tunnel to smash that red sap and get the first rune, which is inside that room and high up on the right. There's also a new lore Shrine in here to read, too!


Now go back out to the place where you got the crystal and lob it at the sap on the bridge up above you to drop it, and spawn some more enemies for you to take out.


Cross to the other side and on your right is another Lore Marker behind some more sap - go back for some crystal and smash this in the same way to read it with Atreus.


The second rune is directly to the North-West, at eye level, if you turn to face that direction just after crossing the bridge.


The third is on a higher level, which is accessed by raising the bridge you just crossed back up to where it started to use it as a ramp. Go to the right of the bridge and pull the wheel, then freeze it in place by throwing your axe at the cog.

At the top, the third rune is immediately on your right.


To your left there's also a coffin - containing a Hel-Reaver! Defeat it to earn the loot you would have got from the coffin, then recall your axe and jump down onto now-lowered the bridge below again to return to the Nornir rune chest. Inside is another Idunn Apple.


Cross the bridge once more, continue straight on into another short tunnel and climb the marked wooden panels to reach a set of doors and, at last, The Summit.

The Summit

You're almost there!


After fixing Atreus' quiver with one of those special arrows he got from Sindri, plow on through the heavy snow and beautiful surroundings to fight some more Hel-Reavers.

At the far end, climb up the marked parts of the stone and work your way all the way around to the right, listening to the conversation of those antagonistic gods up above. Climb up to the top, and you'll find a Scottish-sounding man trapped inside a tree. His name's Mimir.


Mimir is very smart, but he has some bad news: the highest peak in all the realms isn't this one. It's the Giant's Fingers in Jotunheim, another realm entirely! If you want to scatter Atreus' mum's ashes at the highest peak then, you need to go there, and it won't be easy.

Next up: God of War - A New Destination, Go the Serpent's Horn.

Finish up the cutscene and grab Mimir's severd head (it'll make sense in the cutscene...) and your next destination is back down at The Witch's house. At least Inside the Mountain is now finally complete!
