DD and a few friends are going camping next week. I haven't been camping for so long I'm struggling to remember what they need!
Please share with me your camping essentials.

Baby wipes
Earplugs
Swiss Army knife
Duct tape
Re-chargeable torch

These are important items for your camping essentials checklist:
Tent (and footprint, stakes)
Sleeping bags.
Sleeping pads.
Camping pillow.
Headlamps or flashlights (and extra batteries)
Camp chairs.
Camp table (if no picnic table)
