The ratway trouble in skyrim?

OK, I got you bro. Go to Riften, obviously. I need you to go the Main Marketplace where everyone is selling stuff.

Approach Madesi, the Argonian Lizard guy. He's green with horns and he sells jewelry. Get about 2 feet from him, face him. Im giving directions from him.

Now turn to your left, you will see a path.

Go over the bridge, take a right on the boardwalk, take another right where the path ends, go down the stairs, left across the bridge, and theres the door to the RATWAY on your left. There should be barrels and torches around it. :)

It's basically the sewers under the city. It is hard to describe, but I will try:

If you are walking past buildings, you are on the wrong level. Right through the center of the town is a waterway and, you will find stairs leading down to wooden walkways over the water. If you go down there, you see doors, one of which leads to the ratway.

if u are ever lost again just get the spell carnivorence or somthing like that and it will show you the way
