Devon/Cornwall sites with good road access

We have a car and caravan similar size to you SPR, just not the extra 6” on the caravan width.  As mentioned Carnon Downs would be easier for you but we have been to Merrose quite a few times with our big outfit and apart from a couple of short, narrower places (easily seen) the road is fine and the site quieter than Carnon Downs.  Good luck and enjoy the holiday. 

There are a few reasonable roads in North Cornwall. The A39 , grandly called the Atlantic Highway, is not dual carriageway but is not life threatening.

Adjacent to that road, with easy access from north or south,  there is the attractive WillowValley Holiday Park at Bude - small and select with about two dozen pitches, nicely landscaped, privately owned, and sheltered from the storms which afflict cliff top sites like Trewethett and Damage Barton. It’s only just out of Devon into Cornwall so will suit those who don’t want the long haul down to the far west, but it’s a couple of miles from the sea so better for those who can drive to the beaches with a car rather than those with a big motorhome.

Reviews and photos on line for anyone interested .

SPR, in your shoes, I'd use Googie Earth Street View to check out entrances and approach roads. 

Look to R&R for experience of an 8 footer. He, too, asked for advice before towing in this area and he wasn't new to towing.

Enjoy your trip.

Beechcroft C.L., near Kingsbridge, is situated directly off the A38 (it says A381 but it's basically the same little bit of road joining two parts of the A38)

The C.L. is plenty big enough to accept your outfit. If going the only difficulty is maybe the entrance which is a slight cut back if travelling west but I suggest turning at the roundabout about 100 yards further on and coming back east. Much easier. Not sure if C.L.s are your thing though.

There are a lot of CLs close to the A30 when travelling between Devon and Cornwall, might be worth a look.

Also as Euro says the Atlantic highway A39 has plenty of sites, especially around Newquay and there are sites near Padstow that aren't difficult to reach via Wadebridge and the A389. Padstow Touring Park is a good one.

Yes, good choice, Brue. But those with large vehicles should approach Padstow from the roundabout on the A39 at Winnards Perch  and not through St Issey village. 

Euro. It's  the way we used to approach with our long caravan outfit but it all requires a bit of patience. The other routes are very narrow. We used to take our van to Trevitha Farm CL. (Definitely not for nervous drivers but worth the effort!)

Stover campsite, no road issues, near Newton Abbott country park next door beautiful site with bus stop outside gates to Exeter, Torquay, Painton and Brixham and anywhere else you fancy.

Across the road opposite the entrance is Stover golf club where you can use the bar and restaurant with a 10% discount.

Site is very reasonably priced too half the price of the sites with toilet blocks. 

The only issue but not an issue for us is there isn’t a toilet block.

check it out.

Yep, that was one of the first I mentioned.👍🏻

Handy for Torbay and Dartmoor and with Trago Mills shopping complex and eateries nearby.

 That's exactly what I do, Tinny.  And now that I've got the new Tom Tom working - I transcribe that route I have checked on Street View to MyDrive (https://mydrive.tomtom.com/) and download that EXACT route to the TT device.  That way, I know I'm not in for any nasty surprises if it suddenly wants to do it's own thing.

And I agree with flatcoat about 'claiming the road' - something I was taught on my motorcycle course - most decent people will let you through when they see the size of the rig (but not all and that's where 'being careful' comes in!)

I still remain cautious, however, and err on the side of caution and am not swayed by the argument that if a bus or HGV can get through - then so can you. A scratch (or worse) might not matter on a bus but I would be more than a bit upset if it happened to my pride and joy
