Do you mind if I type in English?
Start your essay with the place/venue/location. Then continue with the basic info like the teachers involved, describe more about your friend or even luggage.
Then you continue with the contents like the activities done during the camp, like, collecting logs, ghost stories, born fires, cooking, swimming, etc etc...
End your essay with feelings about the camp, or even your opinion about it. If you can add proverbs(peribahasa) please do. This I guarantee will make a terrific essay.
