Cudmore Grove

Cudmore Grove Country Park is an amazing Nature Reserve on Mersea Island. Nestled on the coast where the Colne Estuary meets the Blackwater Estuary you'll find impressive views across the park and estuaries, sandy beaches and salt marsh, rolling grasslands and meadows buzzing with wildlife. With over 102 acres, there is space to explore, relax and enjoy. The Park is designated as a Special Site of Scientific Interest, a Ramsar site, National Nature Reserve and Special Protection Area and a great variety of biodiversity can be seen and heard.

Come and explore our coastal walks, beach and themed kids play area, designed especially for Cudmore Grove. It's the perfect opportunity to play, laugh and let imaginations run wild.

The area is also rich in historic features, including WWII pillboxes and gun emplacements. Discover the remains of a 16th century blockhouse fort and a cliff that has produced 300,000-year-old fossils!

Cudmore Grove is a flat site with easy walking ground mostly accessible for wheelchair users. Several miles of walking paths circle and cross the site, including the Sea Wall walk, crossing the grasslands and along the sides of the grazing marshes.

Wildlife and birdwatching

A wildlife hide overlooks the pond where you can often see wildfowl, foxes and rabbits. The low-lying grazing meadow is managed as an Site of Special Scientific Interest (SSSI) nature reserve attracting wading birds and ducks throughout the year.

Winter is the best season for birdwatching with sea-duck and grebes in the Colne estuary, up to 15 types of wader on the rich mudflats and maybe a glimpse of a hunting bird of prey like a peregrine or marsh harrier. On the grazing fields in winter, lots of wigeon and teal can be seen as well as large flocks of brent geese, while in the summer lapwings and avocet often breed.

Spring and autumn bring migrant birds such as warblers, wheatear and whinchat, maybe something rarer. Grass left long throughout the year attracts small mammals, skylarks, lizards and insects while kestrels and barn owls hunt over these areas.

On summer days up to 15 types of butterfly can be seen in a day feeding on the meadows and hedgerows.

Historic features

Cudmore Grove has several features of ancient and more recent historic importance. Walks along the sea wall pass the remains of a 16th century blockhouse fort and a cliff of exposed 300,000-year-old fossils.

Part of a golf course between the wars, Cudmore Grove became a defence site during WWII. Visitors can follow the WWII heritage trail to learn more about the wartime structures visible in the park, including several pillboxes and gun emplacements.

After WWII, the land was farmed until purchased by Essex County Council in 1974 as a site for recreation, and historic and conservation importance.

Foot ferry to Brightlingsea

The foot ferry between Brightlingsea, Point Clear and East Mersea provides easy access for local people and visitors from early April to end of October. The boat’s ramp can be lowered for wheelchair users and cyclists. The crossing to Brightlingsea takes around 9 minutes.

See Brightlingsea Harbour for foot ferry sailing and fares.

Cycling and horse riding

There are designated routes for cyclists and horse riders marked on the Map of Cudmore Grove - PDF, 108KB. Routes also allow horses access to the beach. Cyclists are welcome to stray from the designated routes on the park with care for other users.

Please note that the lane that gives access to the carpark is not suitable for towed horse boxes, however, horses can be brought to the car park in lorry-style horse boxes.


We’re always looking for volunteers to undertake tasks alongside the rangers, such as clearing litter from the beach, trimming branches, repairing fences and maintaining signs.

It's a great opportunity to learn about conservation, develop skills and make a difference to the park.

We also welcome young people volunteering as part of school work experience and Duke of Edinburgh award.

You can volunteer during the week or at weekends, depending on what suits you. Please wear appropriate clothing for outdoor work - we’ll give full training and provide equipment. Call 01206 383868 to talk about volunteering options.


You’ll find public toilets at the car park, including disabled and baby changing facilities.
