Getting thereEditThere are no requirements to enter the Chaos Tunnels. The quickest route to reach the Black Demon room is to enter from the rift north of the Monastery which leads to Gargoyles, from there players should head for the larger of the two Mummy rooms which leads on into a Monk of Zamorak room, then from there to head past the Dust Devils (careful not to misclick and attack them without a facemask or slayer helmet).
To enter you must have a Dungeoneering level of 70. Inside there is a total of 9 black demons within a multi-combat zone. The black demons here can be safely killed with range, magic, or even a halberd with the use of a safe spot. There is one black demon secluded on an unreachable platform on the right of the entrance.
There are 4 known safespots within this dungeon. One of them near the entrance, one near the south-west corner of the room, one in the south centre (just east of the south-west spot), and one behind a rock in the south-east corner. If you are using a halberd, you can take advantage of the fact that it allows you to attack from a space away.
