This is the Curley Oak in Wentwood Forest, possibly the oldest tree in Wales and could be 500-900 years old from what I’ve read. It was a foggy day and made for an interesting shot of it.
This is a hotel complex with a difference, all the rooms are tree houses with different themes. The mirror walled room that disappears into its surroundings is probably my favourite, but I would be happy to stay in any of their tree houses.
