I got this game a few days ago, and now I'm stuck. Can anyone help?

I just got the double jump from the boss in the ancient basin, and have been exploring the rest of hollowness (that I can get to). I got a nail art as well from the guy in Greenpath, but I don't know where to go, can anyone help?

edkt: I forgot to say, it seems that I need an ability that will let me go swim in the boiling water, I think.
