Some quick history of the site. Caldons used to be a Forestry Commission owned campsite for caravans and tents and provided very basic amenities such as an electric hookup, water and a toilet block - it was fantastic. It closed around 10 years ago, the toilet block has been levelled, the electric hookups are long gone and the water supply is no more.
However there is a vast amount of level grassy pitches (although the grass is knee height!) There is also a lot of mixed broadleaf woodland, two rivers running through the campsite and a loch adjacent.
I would guess that the site is around 30 acres - there is a house on the site which was lived in by the campsite manager, the house has not been lived in for 10 years, although it was recently sold by the Forestry, not sure whether someone is now living there or whether it is still being refurbished - it needed a lot of work.
The path for the Southern Upland Way goes right through the campsite, also the site is used by lots or ramblers and dogwalkers.
There is parking right next to the site, although a locked gate prevents direct vehicular access.
I would suggest that the best place to camp (out of the way of the main walking traffic) is to go through the gate and over the bridge, follow the tarmac path, don't go left to the information sign go straight on, the path will then branch off to the left as well as going straight on, go straight on and look to your right - there is a decent sized level field, surrounded by trees on two sides and is tucked out the way from passing foot traffic?
