Formby Beach is extremely popular with visitors on sunny days.
Often named as one of the country’s best beaches, its stunning sand dunes stretch for miles, with hundreds of acres of woodland beside it.
Day-trippers from near and far flock to Formby when the weather is nice.
But visitors have now been warned they could face a hefty fine if they bring one banned item to the beach.
National Trust, which owns the site, has told visitors they must take litter home or use the large car park bins.
They must also not bring barbecues to the beach or light fires anywhere on site.
Part of a Facebook post from National Trust Formby reads: “Together we can help protect the wonderful wildlife here at Formby’s nature haven.
“Thank you for your support.”
Anyone who takes a barbecue to Formby Beach could be hit with a £400 fine from Sefton Council.
Barbecues are strictly not allowed, the council says, due to the potential fire risk, injuries caused by discarded barbecuing kits and potential damage to habitats.
Last summer a little boy was left temporarily unable to walk after his foot “melted like wax” in a barbecue accident at the beach.
Nine-year-old Will Tyler also needed a skin graft after he stepped on hot sand where a disposable barbecue had been.
