I was lurking for some new manga to read and came across this post that spiked my interest. The premise of the manga was thrilling however the OP didn't know the name of it. I tried to find it myself but couldn't find anything. I really want to read it but I wasn't sure if the OP wanted to post it here but I'm desperate right now. You can find the summary at this link: http://www.mangago.me/home/mangatopic/4077639/

Please help!
Thanks!

P.S. I'm sorry if the link doesn't work out at first. I'm very new at this so please tell me if you can't see it.

As someone already said in the comments, it seems a lot like Wild rock!
Maybe OP got some details wrong or maybe in fact it was another manga over all but the camping and mountain stuff was defo in wild rock.
