Cromwell Bottom Local Nature Reserve

Cromwell Bottom Lagoon

Cromwell Bottom Local Nature Reserve (LNR) is in the Calder valley between Brighouse and Elland. In the past, the site has been a quarry, a tip for ash from the old Elland power station, and a land fill site. Now it is a mix of woodland, wetlands and grasslands, and is rich in plants and wildlife. Situated next to the Calder and Hebble Navigation, the River Calder runs through the reserve.

What to see

Cromwell Bottom is considered to be one of the most important wildlife sites in Calderdale. The wetlands and meadows provide a variety of habitats for many insects, such as butterflies and moths, dragonflies and damselflies. A bird feeding area helps to attract many birds to the site. These include bullfinch, dunnock, woodpeckers, robins, redpoll and many more. Other birds that can be seen or heard around the site include kingfishers, oystercatchers and curlew. Many mammals and amphibians have also made Cromwell Bottom their home.


The reserve is wheelchair friendly, with many of the paths being suitable for wheelchair access. The paths are generally smooth, and there are no steep gradients. A RADAR key is required to open the gate fully to allow easier access. An audio tour is available from Natural England: Cromwell Bottom LNR .

The reserve is accessed from the A6025 (Elland Road). Turn along a road by the side of Cromwell House (a large red brick building), then left under a height barrier into a small car park. The reserve is signposted from the far end of the car park. There are also buses that travel along the A6025.
