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.
