Open Question: Camping themed party ideas? 10 points for best ideas!?

I'm going to host a camping themed birthday party.
I've booked tents at a water sports club.
So far i've planned renting equipment such as surfboards and body boards and also a bonfire.
What activities can we do? and what food should i buy to cook in the bonfire?
Additional info: 16 year olds girl's party, on a beach.
