It's thought that Yr Wyddfa (Snowdon) is the busiest mountain in the United Kingdom with approximately half a million people traversing the summit every year.
Most visitors are blown away by the beauty of the 1,085-metre peak, but not everyone enjoys the experience.
On the review website Tripadvisor, Wales' highest mountain has a five star rating with around 98 per cent of users rating Yr Wyddfa as either 'excellent' or 'very good'.
But there has still been some negative feedback, with 21 people leaving a 'terrible' rating, alongside some peculiar reviews, North Wales Lives reports.
From complaints about the smell, lack of toilets and even how "exhausting" the ascent is - not everyone has positive memories of their visit to Eryri's highest peak.
You can read some of the often amusing feedback below.
New York-based Tripadisor user Adhsz W complained: "There are no lavatories for all those who climb up and trek back.
"People seem to relieve themselves out in the open giving a whiff of urine smell everywhere in this hillside."
Richard A said: "Every rock you go behind smells of wee or has human excrement behind it, I walked behind a building at the top to find some poor woman taking a dump.
"Lots of visitors here so it’s building up into a veritable sewage fest."
One review was especially puzzling given the fact that the person in question was seemingly aware they were going up a mountain.
Kizaaa said: "I did the Pyg track there and back and found the ascent horrific - so exhausting. Rubbish views of ugly rocks and a couple lakes sometimes, would never do it again."
Visitors complaining about the lack of toilet facilities will be delighted to hear that Hafod Eryri, the cafe at the summit of Yr Wyddfa, will soon be reopening for the first time since 2019.
The building will re-open its doors on May 13.
Last year it was reported that the English name for Wales' highest mountain has been replaced in favour of its Welsh counterpart, after park authorities backed a motion to make the language change.
The English names will no longer be used to refer to the mountain and the national park it sits in, after Snowdonia National Park authorities voted on Wednesday (November 16) 2022 to use Yr Wyddfa rather than Snowdon and Eryri rather than Snowdonia.
