Police in Eryri-Snowdonia said almost 40 vehicles were removed from mountain roads in the national park on Good Friday because they were parked dangerously.

North Wales Police said 29 were recovered near Llyn Ogwen and nine at Pen y Pass.

A spokesperson said: “The irresponsible and dangerous parking we witnessed in Pen y Pass and Llyn Ogwen not only risks lives, but also prevents emergency vehicle access.

“Parking in other parts of Eryri national park will continue to be monitored over the bank holiday weekend.

“We continue to work closely with our colleagues at Gwynedd Council and the Eryri National Park to help reduce the risk to walkers, cyclists and other road users.

“Any further vehicles found to be parked on the clearway, double yellows or causing an obstruction will also have their vehicle removed at their own expense. Please heed the warning.”

Part of the A5 through the Ogwen Valley had to be closed at the start of the Easter weekend to deal with the inconsiderately parked vehicles.

Eryri National Park Authority had introduced a park-and-ride scheme in the Ogwen Valley, with a community electric bus, Bws Ogwen, making eight journeys a day from Bethesda to Ogwen, alongside the existing T10 public bus service.

The valley is the starting point for ascents of the Carneddau, Glyderau and Tryfan, while Pen y Pass lies at the foot of some of the most popular routes up Yr Wyddfa-Snowdon. Parking there is by pre-booking only.

An authority spokesperson said: “The Bws Ogwen scheme provides parking in the community of Bethesda with an easy and sustainable way to travel to and from the area, reducing the number of cars on the road.

“The shuttle bus also includes a drop off and collection at Capel Curig twice daily this year.”
