A tourist was less than impressed with their visit to Yr Wyddfa - calling it "too steep" and complaining that people were "crouching down having a poo on the way up". It was just one amusing review left by visitors on Tripadvisor.
Of the highest mountain in Wales, one said: "What are they thinking? It's way too rough and steep. The weather is atrocious and whatever possessed them to put it in Wales? It would be much better in Cornwall."
Another added: "Poo-down should be it’s name, not Snowdon. Can’t believe how many people were crouching down having a poo on the way up. Most off-putting, can’t they go before they climb?"
Elsewhere in the UK, other famous attractions got similar treatment from some reviewers. A tourist left a scathing review of Stonehenge, saying it was "just a pile of rocks". The prehistoric monument on Salisbury Plain attracts more than 800,000 visitors a year, but not all of them are fans.
One review said: "It's a pile of rocks, and everyone on the A303 slows down to look at them. Pointless. Save yourself the time and don't go."
Another commented: "Some humdrum old rocks about twice the height of a Mondeo driver."
Before waxing lyrical about Britain's other "magnificent" landmarks, another compared Stonehenge to "watching paint dry" or a "five hour wait in A&E". Heading further north, one visitor to Blackpool Pleasure Beach was far from happy.
They said: "It's a rip off for grannies. Why expect a granny holding coats to pay full price? As if they're going on the Big One."

At the Eden Project in Cornwall, negative reviews focused on the smell and said people may have more fun "blowing bubbles" in their garden.
One review said: "Grim. The place is rather smelly, just go to your back garden and blow some bubbles. Absolute stinker lads, dead atmosphere."
One tourist wasn't best pleased after a trip to the Giant's Causeway in Northern Ireland.
They said: "Just a pile of odd-shaped rocks. No giants. It positively brims with scenery that loves to be photographed. Although I think the giant is camera shy."
The Angel of the North, just outside of Newcastle, was so disliked by one visitor they compared it to a crashing plane, in their review.
It said: "The artist is Gormley, more like gormless, a friend of mine visiting from the USA has said it reminded her of a Jumbo Jet with its bum in the ground."
Lastly, after climbing up Arthur's Seat - an ancient hill in Edinburgh - one hiker took the name a little too literally.
They said: "No seat at the top. It's called Arthur's Seat. No seat at the top or anyone by the name of Arthur. Total rip. If I had paid to go I would have asked for my money back due to false advertising. Luckily it's free."
Another complained at the lack of a Tesco Express and a Starbucks at the top.
