Okay, this is my wonderful way of sorting it out:

First, get to the Mountain Climber's house. Then leave again at the exit, you'll be on that big field where you place poles. Look at the ground and you'll see it's made up of circles. Go straight down from the house and eventually you'll reach a place where you can find the spring. Once you touched it go back to the man's house, then go back to the big field. Walk down 2 "blocks", then walk right 2 blocks. Keep your eye on the blocks while the screen is spinning, and soon you should be at the Snow's place.

I may have got them mixed up, so it's worth trying going down 2 than right first.
