AA 5 Pennant Platinum Park – awarded to the very best campsites within the 5 Pennant rating

A haven of tranquillity, far from the stresses of modern day living. Nestling in a valley, surrounded by farmland, our award-winning Park is in the heart of the Roseland Peninsula. This uncommercialised area of Outstanding Natural Beauty, along with our quiet Park atmosphere, is ideal for those seeking the perfect rural retreat.

Just 3 miles from the quaint fishing villages of St Mawes and Portscatho, yet only a mile from the sea, within easy reach of many places of interest.

We are very proud to have been awarded the Enjoy England Gold award for exceptional quality and service beyond the usual 5-star rating.

Wonderful site to relax and it's not in the Tranquil Touring parks brochure without good reason - so if you want to play loud music or keep everyone awake until the early hours please don't come. Facilities are top notch, dogs are very welcome and all the team are very helpful and friendly. Thought it could not get any better, but when they decided to go adults only what a bonus !! Brilliant, Superb etc etc.

First time we have visited, and certainly will not be the last. The location is lovely, and we had the most peaceful stay. As the title stars, the site is immaculate, and the owners evidently put their all in to keeping it that way. We are seasoned campers, and we have no hesitation in stating that this is the best site we have ever stayed on.


This is without a doubt the best site we have been to. Beautiful tranquil setting in the delightful Roseland peninsula, extremely well organised but also very friendly and welcoming. The owners and other guests were all lovely. Facilities were immaculate and there is decent sized very pleasant dog walking area. The best thing for us was that everyone really does keep quiet within the set times of 10.30 and 8.00am, and generally very peaceful all day. I have to say as a coiled travelling without children in the school summer holidays this place is a godsend!
