"The mountain is high."

Translation: 산이 높습니다.

[FireJade]

Could you say something like 산은 키가 큽습니다, or does that construct only apply to people?

[jiwoff]

키 mean height as in a person's height, so no, u can't use 키가. Also, 높습니다 means tall/high, so it would be better than 큽니다 which translates more to 'big', in my opinion.

[CatRamirez4]

Would high been the same as tall?

[jiwoff]

yes, depending on context :) for example u would say "a tree is tall" and "a mountain is high", but u can use 높습니다 both times.

-이 = /i/ otherwise. But, here in 산이, it sounds a bit like /ngi/. S.o., please explain :)
