What Ice Rings? If you're referring to the Ice Arrows, you retrieve them and the Fire Arrows the first time you visit the inside of the Mother and Child Isles. If you're referring to Ice Ring Isle, you can't "get" it. The only island you can "get" is the Private Oasis.
You first need to learn the Wind God's Aria from Gale Island, but in order for you to get inside, you will need the Iron boots from Ice Ring Isle. After you learn the song, you will be able to find Makar in the waterfall on Forest Haven
