The Cuckoo Walk is associated to the Marsden Cuckoo Festival which takes place each year on a Saturday in April when the Yorkshire Pennines village celebrates the coming of Spring. Legend has it that many years ago the people of Marsden were aware that when the cuckoo arrived, so did the Spring and sunshine. They tried to keep Spring forever, by building a tower around the Cuckoo. Unfortunately, as the last stones were about to be laid, away flew the cuckoo. If only they’d built the tower one layer higher. As the legend says, it "were nobbut just wun course too low." The Cuckoo Walk is a strenuous upland circuit of the Pennine moors which begins in Marsden and goes via Willykay Clough, Little Moss, Northern Rotcher, Black Moss Reservoir, Featherbed Moss, Wessenden Head Moor, Black Hill, West Nab, Wessenden Reservoir and Butterley Reservoir. The route is partly coincident with the Oldham Way, Pennine Way National Trail and Kirklees Way.
