Overcrowded Snowdon has been compared to Mount Everest after footage showed the peak packed with visitors over the Bank Holiday weekend.
Video of long queues along the summit has been shared as record numbers hit high during holidays, North Wales Live reports.
The scene was compared to what has happened in Everest recently as locals blamed the Welsh government for its 'heavy promotion'.
Nepal authorities have been slammed over the number of people issued permits to scale the mountain, leading to traffic chaos on the world's highest peak that may have contributed to a number of deaths.
Ian Drew, who regularly climbs areas of the national park in Wales, filmed a clip on Snowdon that shows trekkers battling adverse weather as they line up to take pictures at the 3,300ft peak.
Exhausted hikers can be seen resting as others wait patiently in queue to get to the top.
Ian wrote on Facebook as he posted to the Proud to be Welsh group: "Bank holiday traffic even on Snowdon this weekend, what a shame I have stood on here many times just me and my kids never seen it like this."
Nearly 250 people reacted to the post, with some describing the scene as 'horrific' and 'ridiculous'.
Helen 'Gibbs' Lloyd said: "Wales is becoming unbearably busy during hols. Good for some business but some just camp up anywhere and leave garbage and human waste behind because they don't want to pay campsite fees."
Gloria Ryan wrote: "Looks like what is happening on Everest!"
Many believed that the Welsh government was to blame for the huge increase in visitors climbing Snowdon.
Conservation charity, The Snowdonia Society, said visitors causes problem such as overcrowding, erosion to footpaths and litter up Wales' highest peak.
David Archer, chairman of the charity, said: "Snowdon is being quite heavily promoted by the Welsh Government and the tourism board as an adventure location which is great for local businesses and the local economy, but this does create implications.
"What we do think is important is that the National Park Authority does have adequate resources to manage and maintain the area.
"Resources are being cut, and the National Park Authority don't have the same budget or the number of wardens as they did ten years ago.
"The number of people climbing to the summit are rising exponentially and when the numbers are increasing, but the number of people to maintain the mountain are being reduced, it is going to have an effect."
The large influx of tourists bring an estimated £69 million to the economy every year, according to the National Park Authority.
A spokeswoman for National Park Authority, said: "All revenue from our car parks for example are invested back into managing footpaths on the mountain and maintaining facilities.
"But it’s not enough. Snowdonia National Park Authority has half the resources it had 20 years ago, and visitor numbers have at least doubled."
As well as working with Gwynedd and Conwy tourism departments to encourage visitors to come at quieter times of year, the National Park Authority says it is working in partnership with the Welsh Government to launch the Snowdon Partnership Plan, which aims to protect the area.
