First you will need to get access to the Indigo Quarry, you will need to have a Slime Key to open the Gate, the easiest Slime Key to get is from the first Pink Gordo.
You can check my guide on bursting a Gordo which will show you how to get the key to open up the Indigo Quarry.
Once you have the Key follow this video to get to the Indigo Quarry if you don't know the way already
