Exploring bunkers:

• Always get permission from the owner 
• Take a torch, a spare and one more for luck
• Don't go alone & tell someone where you will be and for how long
• You will get dirty as most are often full of rubbish and may have been used as a public toilet
• Anything you find still belongs to the person that owns the property
• Unexploded ordnance is still found in Jersey if you see or find anything that looks like ordnance please call the bomb disposal officer on 01534 612 612.
