Repeat trips from Bristol to Wales could land you a fine of almost £2,000.
The maximum fine for repeated breaches of the coronavirus lockdown rules in Wales will rise from £120 to £1,920, First Minister Mark Drakeford announced on May 20.
While people in England can take their exercise further from home since restrictions were relaxed earlier this month, those in Wales have been ordered to stay local.
A day-trip from Bristol to Wales could cost you £60 for a first offence and £120 for further offences.
But the charges are set to be raised significantly from the start of Friday (May 22), ahead of the bank holiday weekend.
A first offence would lead to a £60 fine, a second to £120, a third to £240, a fourth to £480, a fifth to £960 and a sixth to £1,920.
In recent weeks there has been a spate of reports of people breaking lockdown by travelling from Bristol into Wales.
The tougher penalties had been requested by the four police forces in Wales, in a bid to deter people from repeatedly breaching the stay-at-home regulations.
Evidence from the four police forces shows a small minority of people are breaking the coronavirus regulations by travelling to well-known beauty spots throughout Wales, says the Welsh Government.
More than 1,300 fixed penalty notices have been issued across Wales since the lockdown restrictions were introduced on March 23.
Mr Drakeford said: "I am very grateful to the chief constables and our Police and Crime Commissioners for all the work they have done to keep Wales safe throughout the coronavirus pandemic.
"The police have adopted a ‘4Es’ approach to the regulations – they have engaged people, explained what they need to do and encouraged them to comply. But when people haven’t responded, they have used their powers to enforce the regulations.
"Fines are a last resort in the enforcement of the regulations which keep us all safe.
"The evidence from the chief constables and Police and Crime Commissioners shows we need a stronger fines structure to deter that small minority of people who persistently fail to keep to the rules."
