The best campsites in Cornwall for couples

If you’re looking for the best campsites in Cornwall for couples, the answer almost always points towards the adults-only ones. Cornwall has a way of making a holiday feel like a proper escape: the light is different here, the roads slow you down in the best possible way, and once you’re pitched up somewhere quiet with a glass of something cold and the evening stretching ahead of you, it’s easy to understand why couples return year after year.

The challenge is finding the right park. Cornwall attracts enormous numbers of visitors in summer, and many campsites reflect that: busy, noisy, and designed around families with children. At an adults-only site, the whole park is geared towards guests who’ve come to relax rather than be entertained. Tranquil Parks has three member parks in Cornwall, each with its own character and location. Here’s what makes each one worth considering for a couples’ break.

Trethem Mill Touring Park, Roseland Peninsula

If you want the most beautiful setting of any campsite in Cornwall, Trethem Mill is hard to beat. Nestled in a valley on the Roseland Peninsula, the park is surrounded by farmland and sits just a mile from the sea and three miles from the fishing villages of St Mawes and Portscatho. It holds AA 5 Star Platinum and VisitEngland 5 Star Gold status, and the grounds are immaculate: individual hedged pitches, landscaped gardens, a three-acre dog walking meadow, and walking routes that start directly from the site.

For couples, the Roseland Peninsula itself is a major draw. It’s one of the least commercialised corners of Cornwall, and St Just-in-Roseland Church, with its waterside sub-tropical garden, is genuinely one of the most romantic spots in the county. The King Harry Ferry crosses the River Fal to Trelissick Gardens, and Falmouth with its National Maritime Museum and waterfront restaurants is within easy reach. The park has a licensed shop and modern facilities including shower suites and a laundry.

For those searching for the best campsites in Cornwall for couples, the Roseland Peninsula setting alone makes Trethem Mill hard to overlook.

Killiwerris Touring Park owners, one of the best campsites in Cornwall for couples

Killiwerris Touring Park, near Truro

Killiwerris is a small, beautifully kept park with only 17 hardstanding pitches, which gives it a genuinely intimate feel. Run by Josie and Steve, who are keen campers themselves, it has earned an AA 5 Star Gold rating and the kind of reviews that mention returning every year. Every pitch is fully serviced with electric hook-up, fresh water, and waste water drain, and the heated facilities building has wet room style showers with built-in hair dryers.

The location suits couples who want to explore Cornwall rather than simply sit on a beach. Truro is five miles away, the coastal village of St Agnes is four miles, and the Poldark filming locations along the north coast are within easy reach. For 2025 the park added a snooker and darts room and a self-service café with new seating areas inside and out, which makes a rainy afternoon feel like much less of a problem.

For couples exploring mid-Cornwall, it’s one of the best campsites in Cornwall for couples who want both peace and easy access to the county’s highlights.

Cardinney Camping Park, Land’s End Peninsula

Cardinney is the most westerly of the Tranquil Parks Cornwall sites, set in the picturesque countryside of the Land’s End peninsula in West Cornwall. It’s a family-run adults-only campsite with a quieter, more back-to-basics character than the other three parks, which suits couples who want to genuinely get away from it all rather than be near facilities and attractions.

The location puts you at the very tip of Cornwall, with some of the most dramatic coastal scenery in the country on your doorstep. It’s a good choice for walkers, for those who want to explore the ancient landscape of West Penwith, and for anyone who finds that the further west you go in Cornwall, the better everything gets.

When to go

Cornwall is at its most popular in July and August, when roads are busy and pitches book up fast. For couples with flexibility in their travel dates, the shoulder seasons are worth considering. Late May and early June offer long evenings, wildflowers along the coastal paths, and parks that are busy but not overwhelmed. September is many regulars' favourite month: the sea is at its warmest, the crowds have thinned, and the light in the evenings is extraordinary. Trethem Mill is open from May to the end of October. Killiwerris opens from the end of March. Check each park's page for current season dates and availability.

Planning your Cornwall couples' break

All three parks are within roughly an hour's drive of each other, making it possible to spend a week or two touring between them and experiencing different parts of Cornwall in a single trip. Many couples use Trethem Mill as a base for the Roseland and Falmouth area, then move on to Killiwerris. You can browse all three parks, check availability, and find out more about each one on our Cornwall campsites page. If you'd like to explore further afield, our full collection of adults-only parks covers England and Wales from Cornwall to Northumberland.

Frequently asked questions about the best campsites in Cornwall for couples

What makes an adults-only campsite better for couples in Cornwall?
At a family campsite, the atmosphere is shaped by everyone on site, which in peak season means a lot of noise and activity. An adults-only site means every guest has come for the same reason you have: to relax and enjoy Cornwall at their own pace. The difference in atmosphere is noticeable from the moment you arrive, and it’s why most couples who try an adults-only park don’t go back to family sites.

Are the Tranquil Parks Cornwall sites suitable for tents as well as caravans?
Most are primarily set up for touring caravans, motorhomes, and campervans. Cardinney is the most tent-friendly of the three. Trethem Mill offers some grass pitches with electric hookup for tents. Check individual park pages for their current pitch types.

Do the Cornwall parks accept dogs?
Trethem Mill has a three-acre dog walking meadow and is very dog friendly. Killiwerris is also dog friendly. Check the individual park page before booking if you’re travelling with a dog.

How far in advance should we book for a summer visit?
As early as possible. The Cornwall parks, particularly Trethem Mill, are popular and summer pitches can go several months in advance. For peak school holiday weeks in July and August, booking six months or more ahead is advisable. The shoulder seasons (May, June, and September) offer more flexibility.

Can we do Cornwall as a touring holiday, moving between parks?
Absolutely. Many couples spend a week or two touring between the parks, spending a few nights at each. All three parks are within about an hour’s drive of each other. Moving between them gives you a good range of the county, from the Roseland Peninsula in the east to the Land’s End peninsula in the far west.
