My favourite place to camp is Ruberslaw in the Scottish Borders. There are pitches within old garden walls or you can wild camp around the estate. They will drive your gear to your site where there are composting toilets, water taps and wood for fires. Dogs are allowed. There is a village close by with a great fish and chip shop too. NO MIDGIES.
The Caravan and Camping club Scone site was lovely but very tame. Dogs are allowed. Midgies weren't that bad. Very close to Scone palace.
There is a lovely small site called north rhinns in Dumfries. It's adults only, I'm not sure about dogs. Midgies were pretty bad.
Milarrochy Bay Caravan and Camping site is right on loch lomond. If you have wetsuits you can bumble about in the stream that runs into the loch. Don't swim in the loch unless you're experienced and equipped, it's very cold and very deep. Midgies just ok.
Glenmore campsite in Aviemore. Neighbours were very loud and drunk shouting for their dog all night so that's how I know dogs are allowed. Midgies from hell.
Port Ban on the Mull of Kintyre is beautiful, allows dogs and the midgies weren't bad. There are a lot of campsite rules and it's in the middle of nowhere but we enjoyed that aspect.
Sands Caravan and camping in Gairloch is so beautiful and dogs are allowed. We will definitely go back. Can't remember if the midgies were bad.
