Before you go down
At the entrance you leave your bags and cameras in lockers and put on a hard hat. Your guide briefs the group on the rules, chiefly that no photography is allowed inside. Then you begin the descent.
The walk itself
The access ramp is steep, and some tours offer a small monorail while many involve walking down and back up. Inside it is cool and damp, and the ceiling is low in places, so you stoop where the hard hat earns its keep. You reach a sealed point, then return.

Knowing what is coming makes the tunnel a highlight rather than a shock. For most visitors it is the most memorable part of the whole day.
