Emergency services has released a warning to beachgoers against digging holes on the beach as they are potential death traps.
The Coastguard is telling people to avoid the beach activity over fears could fall into the holes and get trapped under loose sand.
In some cases the large amounts of sand surrounding their body can even suffocate people to death.
In 2005, three-year-old Abbie Livingstone-Nurse died after falling into a hole dug under the sand at the high tide mark at Upper Towans Beach in Hayle, Cornwall.
In a similar case in 2014 Isabel Grace Franks, 9, was digging a large pit at an Oregon beach, in Lincoln City, America, when it caved in and suffocated her to death.
Coastguards in the south west are now taking the potential dangers so seriously they have carried out a recent training exercise to dig someone out of a hole on a beach in Somerset.
Jon Kendray, senior coastal operations officer with the Coastguard in Weston-super-Mare, told West Briton: "Digging holes in the sand is something which can be seen by many as a relatively harmless exercise.
"But it can have very serious consequences. We would advise people not to tunnel or dig under the sand and only dig shallow holes.
He added: "Children should be supervised by an adult at all times. Any shallow holes should be filled in afterwards.
