The town’s cub group didn’t let the closure of Royston Cave during the winter months stop them from joining in a national challenge to go potholing.

The club donned their head-torches for a night of excitement – but rather than climbing into weathered rocks, the inventive crew went caving in cardboard boxes instead.

This year marks one hundred years since the cubs began in 1916 and as part of the Cub 100 Celebrations, the Scouting Association set a challenge for people to take part in activities below and above ground in February.

The leaders at 10th Royston constructed the caving system using 48 cardboard boxes, five rolls of parcel tape, and several ground sheets. They first drew out a simple plan of the box maze, and then took over five hours to build it.

A spokesman said: “Travelling through the cardboard box caves mimicked real caving, with wider and narrower sections. All in all a great success, and a great evening for all.”
