Know Before You Go
The site is about a mile (1.5 km) hike from the road. This tunnel is difficult to see from the abandoned road and there are trails leading to it. Inside, the base is slippery in areas with wet mud and there are constant drips from the water above. The area has been patrolled by a security force for the canal. Some areas are much more restrictive than others and are under watch. If you venture too close to some areas, you will be asked to leave.
