Mill Heights is a small Certificated Site operated under the Camping and Caravanning Club, located near Calbourne on the Isle of Wight, close to the Caul Bourne.

As a Certificated Site, it is privately run and limited to no more than five caravans or motorhomes at a time, making it a quiet, low-key retreat typical of the Club's network of select smaller sites.

The site offers grass-only pitches without electric hookups and is classed as a Hideaway. Facilities include flushing toilets and washbasins, and pets are welcome with a designated dog walk on site.
