Tulin tells you of the treasure of the secret springs, hidden somewhere in the Hebra Mountains.
Quest Location
After you complete the Wind Temple, Tulin tells you about the Treasure of the Secret Springs.
Find the Treasure
After you find the secret springs, you can look in the middle of the three to find a large chunk of ice. Melt it to reveal the entrance to North Biron Snowshelf Cave.
Go to the end of the cave and you find boulders in the floor. Break them and float down, and you will see some boulders in the south wall on your way down. Break those boulders to make hot spring water pour out.
Then break the boulders in the northeast wall, and the northwest wall, to reveal two more sources of hot spring water.
After you open all three sources of hot spring water, the snow Rito statue will move and you can go into the room beyond to find a chest. It contains the Vah Medoh Divine Helm.
