Stronghold Slayer Cave

There are fewer monsters than the other two caves however, it has monsters you can get in the form of tasks from medium to high-level Slayer masters. There is a cannon inside this cave, and it's near the bank, however it is usually packed.

Catacombs of Kourend

This is a multi-combat zone, so when you train to be a Slayer there you can improve your efficiency and lets you afk a little more. It may take a while to get there without the use of teleports.

Chasm of Fire

There are Lesser, Greater, and Black demons in this area You can also use the cannon in this area with RuneScape Gold. However, it may take a while to get to this area without optimal Teleports since it's quite from the nearest town.
