Jungle is absolute hell.
It's true. You have to cut off all your hair if you're going to be out there for a long time. Your head under the hair is the first thing to get very very stuffy and is a nice home for stuff that want to suck blood out the top of your head.. And yes, just by going out for a 15 minute trek will have leeches sucking on your ankles.
I solved this problem by wearing thick socks.
Not to mention the other bugs chewing bits off you.
Misery is a jungle. This is why in most jungle areas populations never got really large until recently. Also why in Southeast Asia, countries and kingdoms were defined by populations, not by lines on the ground.

yah, i kind of figured that, but i wanted to add in some stuff about constantly having to clear buildings and things of that nature. which is why in urban combat you have such a higher likelyhood of getting killed.

Actually that's what I meant. It might not get you muddy, it might not get you as wet. But chances of you getting killed here is higher than most other places.
A close 2nd or maybe tied could be jungle.
But street fighting has got to be the worst.

if you vote jungle then you havent been in Finland :P

I guess if it snows out too much, EVERYTHING stops. However, I think it makes you and the enemy on the ground more vulnerable to air strikes. It's much harder to hit stuff in the jungle.
So if you have air superiority, fight in the winter could actually be good. Everyone's stuck, but you're the one with the strike ability. In the jungle, it's hard to hit anything because of the canopy cover.
Not to mention no matter what the conditions, you're not going to be bringing your tanks around, as well as most of your heavy weapons. So it's a disaster to attack in. Unless your enemy picks a nice little spot that floods, is surrounded by swamps and is surrounded by hills (Dien Bien Phu!) attacking is ridiculously difficult.

In Finnish army then its summer you ride a bike and then its winter you ski.

Yeah but in winter your trucks and other vehicles will stop.
Then again so are those things in a jungle unless there's a road... which will be an ambush trap because there's not many roads out there.

The hardest to train and fight in is Complex Terrain.

Thick jungle.. you can't use tanks and armored vehicles.
The fight is solely dependent on infantry.

terrain there is muddy and full of unfriendly insects, reptiles and weather.
These are the natural elements to fight first before fighting the human enemy ambushed behind the trees...

It's primitive environment...

I think you'll find any landscape that conspires against you is going to be considered "hard" to fight in. Personally I think urban is a very difficult environment to fight in because it is not one that conventional warfare has learn't to deal with very effictively. In saying that you can also have an urban situation within arctic/desert/jungle climate conditions.

I just believe that with the potential problems of civilian population, multiple levels and facets of fighting, and the propensity for I.E.D's, road side car bombs, suicide bombers etc etc etc plus the issues of landscape and weather make it the hardest to fight well in (in a conventional sense anyway).

It may be more comfortable to live in (e.g. down time between fighting) in comparison to arctic for example, but I'd rather be fighting in dense jungle than clambering through ruined buildings dodging suicide bombers whilst having the civilian population get in the way.
