Hi Robin and Dianne
In 2006 and 20007 we travelled down Italy via Switzerland and a couple of years earlier we travelled down to the Interlaken area. On all 3 occasions we had large (7.2 metre 'vans) - a twin axle in 2007. Although as teachers we have to travel in July/August we did not book any sites in advance but had little trouble finding pitches. I have amalgamated our experiences to give you a route which we found reliable and some campsite recommendations. This route is TOLL FREE to the swiss border.
We travelled overnight arriving at Dunkerque at 06.00. After stopping for a couple of hours sleep at a Aire near Lisle we then drove on down through Belgium and Luxembourg on the E42. East of Namur we turned onto the E411.
Berchen motorway service, near Luxembourg, has the cheapest fuel in western Europe. For a night halt near the autoroute north of Luxembourg I would recommend Camping Chenefleur as an excellent night halt near to the motorway. We discovered this site in 2006 when we broke down on the way home and were towed there by breakdown truck. We stopped off there travelling south in 2007. My review can be found here

The above website has a number of excellent reviews for Swiss campsites
At Luxembourg we turned south onto the E23 and drove as far as an Aire near Nancy before stopping for the night at the aire - an excellent day's drive we felt. The motorway ended just south of Nancy but we continued south past Epinal and then turned west onto the N66. This single carriageway road is a good one which goes through the heart of the Ballons des Vosges mountain range. The views are lovely and although there are some gradients these are relatively easily laid out in long hairpins.
At the eastern side of the Vosges hills we spent a few days staying at the Camping Les Acacias site at Cernay. My review can be found here:

From Cernay we continued down the A35 to Basle where we crossed into Switzerland. In 2007 we crossed into Germany before entering Switzerland which meant we avoided the centre of Basle. I have heard subsequently that the roadworks in Basle are now finished and it much easier to negotiate.
At the border we had to pay for the overpriced annual Swiss motorway vignettes for BOTH the car and caravan. When stopped at the Border point a man comes to sell them to you - 2 are needed one for the car and one for the 'van. We wished to pay by credit card so we had to park up and pay at the office. There are loos there too.
For the Interlanken area from near Basle you would be best to take the E35/A2 motorway then turn onto the A1 Mway toward Berne. Before Berne branch onto the A6 motorway which leads down to Interlaken. The campsites are actually signed on the motorway signs showing the correct turn for each one.
Regarding sites when we actually stayed in the Bernese Oberland a few years back when I looked at Manor Farm, Lazy Rancho and the other central Interlaken sites at the end of July I found them very crowded and was not too impressed. We found two very pleasant alternative sites in the village of Brienz. This is at the far end of the Brienzersee from Interlaken. Both sites are in the Caravan Club's Caravan Europe guide. Below is a copy of a review I wrote soon after our visit.
The 2 sites are both right on the lakeside. There is
Camping Seegartli Tel 033 9511351
This is quite a small site with the only facilities being toilets, launderette and hookups but it in superb position right on the lakeside. We turned up without booking and stayed for nearly 2 weeks. We had a superb lakeside pitch - our van was about 2 metres from the water's edge with uninterupted views along the Brienzer See towards interlaken and the mountains. It is run by a interesting man who lives on site. Although a little officious at times by the end of the visit he had become very friendly. At the end of our stay he actually came out onto the road to stop the traffic to allow us to pull out!!
Camping Aaregg Tel: 03395111843, Email: camping-aaregg@bluewin.ch Website: www.aaereg.ch
Aareg is the bigger of the 2 with more facilities. snack bar, shop, etc. It is is on the same minor road as Seegartli, a little further on. We looked at this but too but chose Seegartli. Our sons regularly paddled their inflatable along the lake from Seegartli to Aareg to buy sweets at the latter campsite's shop!
Both sites feature in the Caravan Club's "Caravan Europe" (Vol 2) which I would recommend both volumes as an essential guide for caravanning on the Continent.
Both sites are very close to the picturessque lakeside village of Brienz which is famous for woodcarving. It is quiter than Interlaken which we found rather busy at times. It has its own railway station, mountain railway and lake boat station within walking distance of the campsite.
We bought a combined rail and cable car pass and hardly used the car all the time that we were on the site. The rail pass gave us access to all the main peaks including the spectacular Jungfraujoch with its glacier and ice cavern and Schilthorn made famous in the James Bond Film "On her Majesty's Secret Secret Service". Alhtough our children were quite young we were able to walk in the mountans by using the cable cars and walking between them.
Interlaken and Meringen are within easy travelling distance and the valley floor is flat enough for cycling. We cycled to Meringen and the nearby Reichenbach falls, where Sherlock Holmes "died"!!?? and, also, visited the Sherlock Holmes Museum in the former English Church in Meringen. En route a very helpful Swiss motorist stopped and, in perfect English, directed us to a beautiful minor road for cycling - all orchards and flower-decked chalets, cos he thought the main road was too busy for our family cycle!! Meringen, also, had a wonderful selection of, free-to-use outdoor toys in a public square near the centre of the town. Our boys had a great time there.
Just writing this brings back many happy memories of a super caravan holiday in staggeringly beautiful surroundings. Switzerland is, also, a very clean and efficient country. Although the campsites were not too expensive we found that food and other things tended to be and I hear that has got worse in 2009 with the present financial situation.
It was a really memorable holiday and still brings back many happy memories.
If you are following my recommendation of Brienz I would recommend staying on the A8 Mway all the way to eastern end of the Brienzersee and then turning onto the Route 6 for Brienz. The road along the northern side of the lake from Interlaken to Brienz is quite narrow and has overhanging rock outcrops which are bit dodgy for caravans.
A general point about Swiss motorways is that although they are good quality roads they are only dual or sometimes single carraigeways with quite a lot of tunnel sections (but then I don't like Tunnels much.) Lorry drivers and other motorists tended to get rather annoyed at us sticking to the 50mph towing speed limit.
I hope this helps.
Regards
Tim
