"Hurry! Let's get the mirror shard from the house of the Snowpeak yeti!"
Snowpeak is an ice region in Hyrule inhabited by the Yeti race (Yeto and Yeta). Snowpeak is the sixth major region Link will enter in Twilight Princess. Snowpeak is a long yet small and snowy region. It has a cave, mountain, the house of the Yetis, and one mini-game. It also houses several Poe Souls.
The way to get to Snowpeak is through an entrance in the Zora's Domain. This area is frozen until after you get the three ancient shadows and they are shattered by Zant (until you need to get there). Link must sled down to the house of the Yetis to reach the area's dungeon. It is about saving Yeta.
