and they were right.
The Cango Caves are a tourist attraction in South Africa.
The guides offer two options to those who wish to explore them, the Standard tour or the Adventure tour.
From the Cango Caves tour guide the following advice is offered before undertaking the adventure tour.
Modern-day adventure pilgrims can experience this “soft adventure” route, providing that you are not claustrophobic and in good health.
Fitness, suitable shoes and sporty clothing (and a bit of guts) are all the gear needed to enjoy the oldest and famous adrenalin icon in South Africa.
Because of the popularity of this touring option among the young (and adventurous!) at heart, the numbers are limited to a maximum of 45 people per group
As it happens on New years day a young woman and her husband decided to undertake the adventure tour which is the only way you can visit the famous "Tunnel of Love".
But entering this section of the caves requires negotiating a very tight and narrow section within the cave system. And the woman concerned was somewhat large (overweight according to the link but described as obese in other South African accounts). So the woman was warned she was unsuited for the route.
"She was told at the ticket office that she was too big to take part in the specific section. (But) her husband insisted she should take part in the adventure."
Gerstner said the guide also told the woman, when she reached the tunnels, that she should reconsider.
"The woman was extremely offended because she felt she was offended in person and laid a charge at management.
"But, she was too big. We will have to be a lot more stringent with people - to adhere to the criteria of difficulty of the routes," Gerstner said on Tuesday.
Having stuck to her guns and insisted on her right to enter the "tunnel of Love" the woman promptly became wedged, trapping 22 other tourists behind her.
It took ten hours and lots of liquid paraffin but the woman was eventually released, freeing those trapped behind her.
You can only feel sympathy for the tour operators here, it is not the easiest thing in the world to tell a woman she is too large especially if she liable to take offence.
But when it comes down to it, we all have to accept our limitations unpalatable as that may be sometimes.
