If you want to learn to fight you need to find a Muay Thai, Sanda or Sanshou school.
A lot of Shaolin 'Kung Fu' may not necessarily be invented by the monks themselves. The style is only associated to them. There's a lot of branches of those schools left having connections to the original founders...studying there isn't that bad to Shaolin study of the same arts.
I'd say that callsignfuzzy is right to some extent that a lot of modern schools don't give you all the answers and may be flawed but they do require less dedications to teach you concepts you can actually understand without as much commitment and isolation from social life.
If you only want to learn how to 'fight' then you need to ask if you really just want to learn how to cripple people with your hands or take in account of vital tactical changes due to advent and possible dangers of long ranged weapons and concealed stuffs....which drastically alters how you would use any style.
Shaolin temples like you imagine them don't exist anymore. There are hundreds of different styles and thousands of different schools out there that you can try out.
I guess when you say tucked away from civilization, what you mean is somewhere that's relatively far from modernity. In South and Southeast Asia there are lots of martial arts schools in remote areas. Many African tribes also practice stick-fighting or some other fighting style. It might help if you were a bit more specific.
No thats the only place you should learn martial arts.
Yeah. Lots of places. MMA, boxing, and kickboxing/Muay Thai gyms, BJJ schools, wrestling programs, karate dojo, Taekwondo dojang, military combatives programs, various Chinese martial arts schools, Koryu Bujutsu (old-school Japanese martial arts) dojo, Capoeira schools, Filipino martial arts schools, etc, etc, etc. Frankly, a good boxing gym would probably prepare you for a fight better than the modern Shaolin temple.
I know you can move to the shaloin temple to learn Kung fu, but is there anywhere else in the world that you can learn to fight? A little bit tucked away from civilisation like the Shaolin Temple
