Maraudon

How to get there:

- The start of maraudon is at 30.0 62.5 in desolace, on the map that's the cave entrance marked in the valley of spears.
- Go through the stone door and follow the path inside.
- You will reach a fork with purple crystals on the left, orange on the right and a small archway in the middle. Take purple.
- As soon as you get into purple jump down to the left, don't cross the bridge, and take the portal to inner maraudon* behind the spirit of kolk.
- Go southeast from the waterfall area. When you leave the waterfall area you'll see 3 subterranean diametradons.
- Follow the path. You'll go under an arch and up a ramp. At the top of the first ramp turn left and go up another ramp (don't turn right.)
- Cross the bridge and you'll be facing a primordial behemoth. Follow the left path.
- You'll come to an area with more waterfalls. DON'T fall off any ledges.
- Follow the path right, then between 2 behemoths and across the long bridge which heads southwest.
- Kill the sexy thing at the end of the end of the bridge. Hearth out! It's impossible to run out.

*Note: You can't use the portal while dead, so don't die. :) If you do die you can res on either the purple or orange sides and run back to the portal.
You can now use the portal while dead!

scepter of celebras is no longer required to access the Earthsong Falls portal as of patch 3.08. The staff itself has been changed to a decent rare item for its level. Also, if you completed the kill quest for the Princess, you will have the achievement.

For those of you going for the achievement using the Dungeon Finder system, use 'Maraudon - Earth Song Falls.'
Once you're in, head south to Zaetar's Grave.
