Hi Chris
We're great "Scotophiles" and spent some of our earliest, tenting holidays in Scotland with our 5 kids- they're too grown up to come now and it just my wife and myself + Max the collie, he's a keen caravanner too!!!! We have been tempted by the continent for the last few summers as the weather is a bit warmer and more reliable than Scotland. Having said that we have said some real scorching days in Scotland too.
Here are some of our Favourite places and sites.
Milarrochy Bay CC Club Site on Loch Lomond. Quite remote, very attractive location right on the shore of the Loch, superb views of Loch and mountains. Good boat launching facilities. The Eastern shore is the quieter side and long distance footpath runs near site. Not much organised for children but good for boating and watersports. Balloch is the nearest town if I remember rightly with a good Co-op supermarket for supplies. Village nearby with a couple of shops.
When we went our 5 kids ranged in age from 4-12 years old. They enjoyed the Loch and its beaches. We, also, had a few car trips out. Inerary Jail where you sit-in on a "trial" and lock Dad in an outside exercise pen was very popular! Glasgow is within driving or train, from Balloch, distance too. The CCC "Your Big Sites Book" Milarrochy Bay page gives a number of trips from the site.
A couple of years ago we stayed at Loch Lomond Woods which is actually in Balloch itself (our car broke down big time and took a week to fix when we were travelling further north) Balloch has lovely loch-side walks and beaches. There's a newish Shopping and entertainment centre on the Lochside in Balloch.
Port Ban Holiday Park on the Kintyre Peninsula. It's very remote but right on its own beach. It's self contained with cafe, shop, library canoes to hire, sports field and some children's activities without being over-commercialised.
Grannie's Heilan Hame, Dornoch. More commercialised with indoor pool, shop, cafe, amusement centre but with the option of pitching as far or near to these as you wish, including right on the beach.
The area around Gairloch in Wester Ross is beautiful although it can be rather windy. We loved the campsite at Gruinard Bay where we camped with a frame tent. It was right on the beach with little river running into the sea which kept our kids amused for hours.
Oban and the coast nearby are beautiful and the road from Fort William to Mallaig has stupendous views and lots of tiny campsites with their own beaches. We've camped on Skye and that is now even better now that the road bridge tolls have been removed.
We love Dumfries and Galloway too. I worked there in my pre-college "gap year" 30+ years ago. I would recommend Brighouse Bay. A large site with a pool and wide range of activities but near to a the sea. Mossyard, Auchenlarrie and Castle Douglas are also interesting in their own way.
All of the above are in Camping and Caravanning Club "Your Big Sites Book"
The website ukcampsite.co.uk has a good range of sites and includes personal reviews by folk who've visited them.
I'd, also, recommend a Guide book we recently bought. Its called "Sea View Camping and Caravanning Sites in Britain!. The author Brian Leahy toured around the Uk finding these sites as retirement project. The book costs
