The Lake at Nine Acres is a small, privately run campsite located in Leigh-on-Sea, Essex, operating as a Certificated Site under the Camping and Caravanning Club.

As a CS, it accommodates only a limited number of caravans, motorhomes, and tents at any one time, offering a quieter, more secluded experience than larger commercial campgrounds.

The site welcomes pets and features a designated dog walk, along with fishing opportunities (a licence may be required). Pitches are grass only.

The surrounding area also hosts a wedding and events venue on the same grounds, set within a lakeside landscape on Flemings Farm Road.
