Calderdale's Hidden Gem

A former quarry, landfill site and ash tip do not sound like the location of one of Calderdale’s best-kept secrets. Cromwell Bottom Nature Reserve, however, is just that! Taking advantage of its ash-rich soil and abundant water, it is home to some of Calderdale’s most diverse habitats for fauna and flora. Surrounded by the river Calder and the canal, it really is a hidden gem, highlighted by our recent guided tour and video below!

Accessible to all

Maintained by a group of committed volunteers known as Cromwell Bottom Wildlife Group (CBWG), the 74-acre site is home to flower meadows, dry and wet woodland, a lagoon, ponds and numerous bird viewing areas. It’s also one of the most accessible nature reserves in the area and almost the whole site can be accessed by wheelchair.  

As part of plans to improve accessibility to the site, Active Calderdale and CBWG installed new signage on the A6025, and more recently compiled two self-guided walk booklets for visitors, including shorter, accessible routes. These can be downloaded below.
