What's this horror movie called? it's either korean or japanese, etc. and had english subs?

i remember it was really gory and there were these teenagers and they were in a canoe thing going down this river or whatever in the jungle and there was this house or shack on the water and there was an old woman there. i think in part (if i am not confusing 2 different movies) that there is a part where this guy takes fish hooks or something and sticks them in this guys eyes to close them or in his lips. i can't remember.
