Altus Tunnel Location: How to Find It

The entrance to Old Altus Tunnel is a short ride northeast of the Erdtree-Gazing Hill. Simply follow the road along until you see the fog gate guarding its entryway along the western cliff wall. Entry requires two Stonesword Keys.

Old Altus Tunnel: Walkthrough

After dissolving the Stonesword Key gate at the Old Altus Tunnel’s entrance, start by grabbing some Explosive Stone Clumps off a corpse before heading further downward. Instead of taking the lift down, drop along the left-hand side of the lift to fall onto a ledge. There’s nothing at this first level, but drop down to the next ledge to find some Cracked Crystals at the end of the blocked off passageway. With those Cracked Crystals in your possession, carefully drop down the rest of the way and rest at the Site of Grace.

To continue, head down the path to the west where you’ll find some more Cracked Crystals and a wooden structure. There’s nothing inside the wooden hut except for an enemy dog, so there’s no need to enter it unless you care to wake the hound. Focus your attention on the miner wielding a flamethrower instead and head down the crevice between the wood hut and the Summoning Pool to snag a Smithing Stone [5]. You’re now free to exit into the next open chamber.

We’ll be dropping down into the ground floor of this chamber in a bit, but for now climb the ladder along the wooden balcony to the northwest. Once at the top, continue to the west to find a chamber housing two miners, an armoured soldier, and two dogs in the wood hut. With them all eliminated, there’ll be nothing stopping you from looting the Cracked Crystals, Smithing Stone [5], Stanching Boluses, and Boltdrake Talisman +1 that are dotted around this room. After grabbing all the goodies, head back out to the previous chamber.

Our next destination in this open chamber is the wooden balcony to the south. Instead of climbing down the ladder we climbed up earlier, drop down onto the wooden pathway that leads to the miners along the southern edge. Eliminate them both to get the Cracked Crystals and Smithing Stone [5] they were harvesting, and grab the Golden Rune [6] from the corpse sitting among the wooden debris. Now we can finally drop down to the ground floor of this chamber.

However, it’s important you’re prepared before you do drop down as there’s a bevy of enemies who will start heading your way down here, including two armoured knights and a pair of dogs. Focus on taking out the dogs first to make the knights a bit more manageable. Don’t be afraid to climb back up the ladder out of this chamber too if things start looking dicey – it’ll give you the space you need to heal up before diving back into the fray.

Once this initial area is cleared of threats, you can crab a Smithing Stone [5] in a dark alcove to the east, the Troll’s Hammer off the corpse in the southern wood hut, another Smithing Stone [5] along one side of the hut, a Somber Smithing Stone [6] behind the hut, and a Somber Smithing Stone [4] of the corpse in the opposite hut. Next, instead of taking the more obvious passageway out of this chamber to the west, circle around the hut to the north to find a different passage.

Follow this hidden passageway to a chamber that contains another dog, a flamethrower miner, a Somber Smithing Stone [5], and a couple more Smithing Stones [5]. With this small side chamber cleared, head back out into the previous room and into the westward passageway we passed up earlier. It leads you straight to the mist gate of these tunnels which blocks off the boss arena of the Stonedigger Troll.
