What is your least favorite dungeon/area in any Pokemon game?

[ChampionMic]

It's a pretty random question, but for some reason I am curious as to what the answers will be. What is your least favorite area in a pokemon game?  It can be a dungeon a route, a gym, a city... heck, it could be as specific as a certain patch of grass or whatever. It can be in any pokemon game at all. It's a pretty simple question. You can hate it for any reason at all. You can also list multiple hated areas if you want.

My least favorites are:
-Pokemon Mansion: So many encounters and such an annoying puzzle. And you have no idea how large of a tantrum I threw when I found out that the red carpet door at the near end of the dungeon sent me back to the beginning. Without repels, I wouldn't be able to keep my sanity.
-Whirl Islands: I had a pretty bad experience there when I forgot to bring Flash. 
-Seafoam Islands: ANNOYING STUPID STRENGTH PUZZLES, and overall extremely tedious. 

Note: I did a search, and I didn't find this post anywhere. If there is already a thread on this subject, please show me the link. Thank you.

Victory Road- Longest Puzzle in G4 games

Nah, the most annoying one was in Goldenrod City, under the dept store with the switches in GSC. The switches didn't have colours then, whilst in HGSS, they are coloured so that you know which switch triggers which doors. But in GSC, you could spend hours trying combinations and once you pressed a couple of times different switches, there is practically no way to reset the switches (unless you noted down what you did in what order).

Then, less of a pain were Whirls Islands, Dark Cave and another dark cave where you get Tyrogue in GSC. The walls and paths seemed so much alike even with Flash on.

As from those, all the rest of the games were easy.

Well, i've never played Gen3 down so i cant testify

Personally Mt.Moon
If you started with bulbasaur/squirtle. You pretty much just kapowed Brock with one lvl 11 pokemon. With the constant encounters, and your low level team, this was absolute hell. Plus, I always got lost ¬_¬

Lol, I could go through Mt. Moon if it was a dark cave with flash required and without using flash, and at the same time get all the items, hidden or not XD

It's only a matter of time before he gets reported. Derp.

Anyway, the dark caves that you need flash for drove me crazy. Especially when I was playing it in the car.
At night.
On red version.
With no light.

two hours of hugging the wall, being bombarded with Zubats that have nothing better to do than poison my charmeleon.

I played so much as a kid, that I have most of the caves that needed Flash memorized...

But Mt. Moon was a pain when I chose Bulbasaur. Still, easily the most hated for me is the Safari Zone. How many Pokeballs can one Kangaskhan break free of? ¬_¬

[Jerry]

And in the early versions... how many safari balls can a Chansey dodge? O.o

PMD-wise... : Sky Tower, or Buried Relic, or any "Level-One" Areas.
Otherwise: Victory Road. Long dungeon is long.
