The area is popular with walkers and a network of hiking trails criss-crosses the area. The Healey Nab area has two small man-made lakes, Bottom Lodge and Top Lodge, a private fishing lake. The two used to be linked to Lower Healey Bleach Works, a finishing works of the town's cotton industry, the remaining structure of which has been incorporated into the sites conversion into a small industrial estate. The summit is Grey Heights, and near it is a disused quarry known as Devil's Rock. Grey Heights and its cairn at 682 feet form the highest point and from there are views over Chorley and it is possible to see the skyline of Preston, Fiddlers Ferry power station in Merseyside, Jodrell Bank Telescope and the silhouette of Blackpool Tower, Blackpool Pleasure Beach and the Irish Sea. From Chorley, The Nab dominates the landscape and is the first significant height gain in the transition from a heavily populated area to the moorland of the West Pennine Moors.
