Ah, any area in MM where it is night time is full of memories for me. I like the cricket sounds and all that stuff. Makes me wanna go play the game right now. I'll need to buy it on VC first, I have the CE, but the game freezes infrequently.
Mountains defenitly. I like the area, the music, etc. Ikana it's a pain just to get up to it. Snowhead was also an awesome temple. I think the upgrade for finding all of the stray faries is the most useful one. It was also cool to explore after the snow melted, to find things as well. Overall...
