I don;t think you can really get away from Death Mountain. It's quite iconic, making its way in many Zelda titles (not necessarily under that name, per se, but still in some other sense). However, my favorite might have to be Gerudo Desert's Mirror Chamber from Twilight Princess. I remember the first time I saw it, climbing that high tower at Lake Hylia and gazing East (I think), wondering what all of those sage sigils were surrounding, and why one was broken...
