There are many reasons to visit Snowdonia - the beautiful yet bleak majesty of the hills, the stunning walks up Wales' highest peak and one of the most incredible stretches of coastline in the UK.
Oh, and there's also the trampolines.
That's right, trampolines. Three of them. All massive. In an even more massive cave.
Snowdonia appears to be slowly turning into one giant adventure playground. There's already a Treetop Adventure and the longest zipline in Europe, but the latest addition is definitely the maddest yet.
Bounce Below is the world's first subterranean trampoline playground. Oh to have been a fly on the wall when that was pitched to a presumably bemused bank manager.
The insane attraction consists of three giant trampolines one above the other attached to the walls of a 176-year-old cavern twice the size of St Paul's Cathedral in what used to be a slate mine.
At it's highest you're suspended 80 ft above the cave floor - all perfectly safe of course.
Even getting into it is is quirky - guests, around 25 at a time, are ferried in aboard a converted mine train, deep into the bowels of the mountain.
It's a little disconcerting to imagine thousands of tonnes of rock above your head bit once you reach the main event this quickly disappears.
Bounce Below is surreal to put it mildly. The massive cavern is illuminated with constantly changing neon lights and you're let loose to discover at your own leisure.
Each trampoline is connected to the others by rope 'staircases' or (much more fun) slides made of netting, the longest of which is 60 ft long.
It takes bit of getting used to - you'll spend plenty of time on your bum before you're bouncing like a pro.
Even then, all it takes is another person to jump nearby and your carefully coordinated efforts will be disrupted.
It is a lot of fun though it is deceptively tiring...
