Safety guidelines

Respect private property

Many sites sit on private land. Always seek permission first.

Never enter unsafe structures

Sealed or unstable bunkers can collapse without warning.

Do not trespass

Restricted military zones are off-limits. Penalties are real.

Avoid flooded tunnels

Cold water, no exit. Turn around at the first sign of water.

Bring light and battery

A headlamp, backup torch, and full phone battery are non-negotiable.

Wear proper footwear

Slippery concrete, rebar, and broken glass are common.

Report dangerous places

Help the community. Flag incorrect or hazardous locations.

Follow local laws

Cultural heritage rules vary by country. Know before you go.
