This former site of an ammunitions works is now 125 acres of grassland and hawthorn woodland/scrub bounded on its south and west sides by tidal creeks and saltings whilst along its eastern side runs Pitsea Hall fleet with an extensive reedbed.
The country park, managed by Basildon Council, supports a large and diverse range of species justified by it being designated as Site of Special Scientific Interest.
Great Crested Grebe
Past rarities include
The country park visitor centre adjacent to the main car park has a shop, toilets (including disabled) and café while across the road the RSPB has a visitor centre and wildlife garden where all the latest bird news can be obtained.
There are two hides with disabled access overlooking the fleet, one is 80 metres from the park visitor centre with the second 30 metres from the nearby Green Centre car park. A key for these hides is available from the RSPB visitor centre or when closed, the park visitor centre.
There are several trails crossing the park from the visitor centre including one with wide hard surfaces. Access to the trails is also possible from the Green Centre and marina car parks.
This approximately 2m (1.2 mile) walk, on a hard surface, takes you around the perimeter of the park and all of the hides. Taking in the fleet, creeks, ponds and woodland as well as the marshland beyond it is possible to find many of the special species that this site supports.
