It's the ultimate back to basics property where you can become a modern stone age family like Fred and Wilma Flintstone
It's a unique property that provides both an escape to the country and a journey back in time.
And for fans of the Flinstones, it's a chance to have a Yabba Dabba Doo time.
The property in question is actually a collection of five famous and historic caves in Wales which are now on the market for offers in the region of £150,000 and can be viewed on Rightmove.
Rightmove’s Director of Property Data Tim Bannister said: "It's not every day that we're able to share such a unique and quirky listing with the world, but this remarkable plot of land has certainly captured the team's attention.
"For the same price as a Kensington car parking space, you can buy 2.5 acres of serene woodland and spend your weekends exploring more than seven miles of your very own underground cave network.
Simon Edwards, partner at McCartneys Estate Agents in Hay-on-Wye, which is marketing the property added: “As you can imagine, the cave market isn’t always particularly buoyant, but we’re thrilled to have been instructed on this listing.
"The land is being sold by a local farmer, and whilst the area doesn’t have any planning consent, it’s a great place to explore and enjoy on foot.”
The property is located in an area of sloping woodland alongside the river Nedd in the upper reaches of the Neath Valley within the Brecon Beacons National Park.
It comprises of a small area of woodland which has good road access and a parking area and the access points into four caves and a further right of way which will be granted to a fifth cave entrance just north of it.
It is situated just within the boundaries of Powys at the foot of the Great Forest hills at the heart of the Brecon Beacons National Park.
There is no prospect of building a dwelling on the woodland, but any planning enquiries should be made to the Brecon Beacons National Park Planning Authority on .
Andy Freem, secretary of South Wales Caving Club, said: “These caves are a major international caving site, of huge scientific and sporting significance, and they date back around half a million years.
"They’re formed of limestone and there are still many parts that are likely to develop which haven’t been explored yet. It’s crucially important that the caves remain cared for, because their significance really can’t be understated.”
