In Darkroot Garden you will find a door sealed with a white circle in the center. This place will get you around 7k souls every 3 minutes (depending on the player level and skill). Sweep the area a few times to boost your character up enough to take down the Gaping Dragon with ease. An average run through the area only takes about 15 minutes, but it will gain you about 10000 souls each time. If you can avoid being cursed, The Depths are a great place to farm for souls.

This will trigger the dragon to breathe fire, killing the new undead, and normally gaining you another 555 souls. Once you have rested at the bonfire, climb back up the ladder and stairs and quickly step onto the bridge and then back down the stairs. Once down the staircase, go through the entrance leading back to the bonefire in the Undead Burg (remember to lower the ladder). Notice that the drake breathes fire, killing many undead and gaining you up to 555 souls.

Once you get the the bridge with the drake at the end, go half-way down the bridge and then down the staircase to your right.
