Patrols should be stepped up at a North Wales beauty spot plagued by a growing fly-tipping  problem.

That is the call from from Llanrwst’s Conwy county councillor Aaron Wynne, who said action was needed at Llyn Geirionydd near Trefriw and Llanrwst, in the Conwy Valley.

Cllr Wynne took pictures of the debris strewn on a table and left by visitors, along with bags full of rubbish left at the scene, saying the problem had got worse since lockdown.

He said he was “angered” by the mess and has written to Natural Resources Wales (NRW) asking it to “ramp up patrols” at the popular lakeside spot.

He said: “The situation at  Llyn Geirionydd has been a problem for a long time but in the last few months things seem to have got worse.

“It’s not fair on the people who live near the lake who have their lives disrupted by this kind of anti-social behaviour.

“We need Natural Resources Wales to step up patrols in the area to prevent this sort of thing happening.

“Hopefully with the weather turning we will see a decrease but we can’t rely on that alone – action needs to be taken to discourage this from happening again.”

Llyn Geirionydd sits on old industrial land at the egde of Gwydir Forest Park, where zinc and lead mining were once the main sources of work.

The lake was reputedly the home of sixth-century poet Taliesin and a stone monument to him stands by its north bank.

Walking routes criss-cross the park, along with two “red-grade” mountain bike trails which bring in outdoor enthusiasts all year round.

A spokeswoman for NRW said countryside destinations had seen “unprecedented levels of visitors” since lockdown.

She added: “Whereas the vast majority of visitors have been well behaved and respectful we have unfortunately experienced some problems with anti-social behaviour including camping, wildfires and litter.

“Some of this anti-social behaviour has occurred on NRW owned and managed property including the area around Llyn Geirionydd.

“NRW has been proactive in this instance and has increased the number of officers patrolling the site particularly during busy weekend periods.

“We have also spent a considerable amount of resources in clearing up the mess left by some visitors.

“We are engaging with Conwy council highways department and police to help address some of the local issues raised.”
