The Chaos Tunnels are an intricate series of rooms located underneath the low levels of the wilderness; the tunnels themselves, however, are not part of the wilderness, so you don't have to worry about Revenants. You can enter this dungeon by entering one of the five ropes going down to it, which is located in the wild just north of Edgeville. Nothing is required for entry to the dungeon but it is wise that be prepared for aggressive meleeing, ranging, and maging opponents.

The entire dungeon is a multi-combat, thus making it a great place to train with Ancient Magicks or your combat familiar. When exploring this dungeon it is best that you be on guard for just about anything from Green dragons to poisonous spiders. The main reason players adventure here is because every monster here drops charms for use in the Summoning skill, and it is much easier and convenient to get to most of the monsters in the Chaos Tunnel rather than to travel to where you would normally slay them. Unfortunately, the only downside of the Chaos Tunnels are that you cannot bring a cannon down. If you do, a message will pop up saying, "The cannon is too heavy to take down there - you'll have to leave it behind."

Note: Sometimes the portals act up and will teleport you to a random room, which is normally close to your destination, so you should always be ready in case you run into a bronze dragon.
