Climbing high - Treehouses scale the heights with Lonely Planet accolade
They have been nominated in the top 50 adventures in the world by the Lonely Planet Magazine and they're in the middle of mid Wales.
The Living Room tree houses in Bryn Meurig, near Cemmaes, are hidden deep in a spectacular forest and totally away from modern day life.
There is no electricity, with light provided by lanterns and lamps. A woodburning stove provides warmth and the shower is spread by a spring.
The tree houses have been built by business partners Mark Bond and Peter Canham who say the lure of the Welsh countryside attracts visitors from across the world.
Mr Bond said they were delighted to be mentioned in Lonely Planet.
"We came in at number 33, between kayaking in Poland and walking the the Black Forest in Germany so we are thrilled that our visitors like us so much."
He said the aim of creating the tree houses had been to make them as much a part of the forest as they could be.
"Peter is the designer. He has created the houses to be at one with nature, yet they are totally luxurious. We have six tree houses, each one secluded from the world and secluded from any other of the houses. We have couples and families that visit us from all over Britain and even from as far away as Hong Kong and Australia."
The company has been based at Bryn Meurig for the past six years and says it is fully booked throughout the year.
Wales has been celebrating a surge in tourism, with the Welsh government launching the Year of Adventure, the Year of Legends and for 2018, the Year of the Sea.
Its tourist attractions include not only the natural beauty from the coast to Snowdonia, its castles and visitor destinations such as Surf Snowdonia and the biggest zip line in Europe.
The Shropshire Welsh border has an impressive number of castles and the Offa's Dyke footpath from Chepstow to Prestatyn.
