Londoners have broken Tier 4 restrictions by travelling to beauty spots hundreds of miles away over the festive period, making them “disappointingly busy”.
Some residents in the capital even went on 222-mile trips to North Wales, flouting Covid rules which ban travelling between tiers.
Snowdonia park warden Arwel Morris told BBC Radio Wales Breakfast that people should not be driving to visit places in the UK.
He blamed people being off work for Christmas and New Year and good weather creating a surge in the number of visitors descending upon the area.

He said: “We try and enforce the fact that exercise should begin and end at home, meaning people should not try and drive to a location where they plan to exercise.
“And this has been really difficult over the last few days.
“We have dealt with people from London, Birmingham… numerous people from North Wales travelling to beauty spots.”
The warden said police had been doing their “absolute best” to help the situation as his team were not able to issue fines to visitors.
It comes as South Wale Police received 240 reports of coronavirus rule breaches on New Year’s Eve.
The force handed out 43 fixed penalty notices on December 31, with 430 issued for the whole month in total.
A spokesman said officers turned away visitors from Southampton, Kent and Solihull on New Year’s Day.
Wales has been under Tier 4 restrictions, like London, since December 20.
