We say...

Many readers have told us how much they love Trethem Mill Touring Park over the years, and the votes flooded in for it again for our 2018 guide.

The facilities are excellent and are located in an easy-to-access central building; amenities at the site include a licensed shop selling local produce, an information area, a motorhome service point and a fully equipped launderette.

Wildlife is encouraged here: as you walk around you’ll spot many bird boxes which attract a wide variety of species, including woodpeckers.

There’s also a dog and nature walk with interpretation boards.

Trethem Mill is located on the beautiful Roseland Peninsula – nearby attractions are the pretty Cornish villages of St Mawes and Portscatho.

You say...

“It’s in a great position on the Roseland Peninsula. The site is immaculate and welcoming. The facilities are spotless.”

“It’s a beautiful, spacious, excellently appointed site. In fact the best site we have ever stayed on in 40 years. We have two large dogs and they are well catered for here with the expansive dog-walking area. It’s huge, scenic and a beautiful nature area with both shaded and open areas. An absolute joy to spend time in – there are even benches dotted around so you can sit and enjoy the lovely views!”
