The Ancient Cistern is my No. 1! I absolutely enjoyed the harmony it exudes with the music, the huge Buddha in the middle, the water lilies...that all goes well together. And then that twist when entering the dungeons' basement. It's totally different and creepy with all the cursed Bokoblins, even the water is poisonus. It allegorises the Yin and Yang perfectly. Not to mention the boss :yes:
My no. 2 is the Sandship. I mean there's no other alternative since you get the Clawshots from Nayrus Silent Realm! I always feel like a corsair when using them
I use to call the Sandship the 'Disney Dungeon' - the dungeon itself totally reminds me of 'Pirates of the Carribbean' and Tentalus looks like a creature from 'Monsters Inc.'
