A collapsed skylight[3] provides easy access to two of the tube's entrances which became a tourist attraction.

Some parts of the tube are located under private property,[4] and so are some of the entrances.

Many natural features, such as the stalagmites and the stalactites have since been broken off by tourists as souvenirs.
