Savage Slough is a swamp area which can be found South-West of Lumbridge Swamp. It was released on the 18th of January 2019 along with the introduction of the Slayer skill. It contains a swamp, Slough Castle, and underneath it, Hell's Refuge.

Most varieties of golems (apart from ice and lava golems) can be found here, as well as werewolves and several convenient npcs otherwise found in the wilderness. It can only be accessed via the bridge from Lumbridge swamp.

Note: players with level 40+ slayer should be careful of aggressive Swamp burrowers when moving through the swamp to the castle.
