Calf Hey Reservoir Weather


Calf Hey Reservoir is a great starter walk for anybody looking to get into walking. Sandwiched between Haslingden & Blackburn on the (B6232) Grane Road, this area is a well-known beauty spot.

There are three reservoirs in total with Calf Hey being the most accessible to anybody, with good paths all the way around which are well maintained. You can walk around all three but it becomes less accessible for everybody and you do have to make up your own route as you go along.

Knowledge Base

Calf Hey is a reservoir on the Haslingden Grane, close to the town of Haslingden in the Borough of Rossendale. It was the second of three reservoirs built in the valley, the others being Ogden Reservoir and Holden Wood Reservoir. and opened in 1860 .

The route starts from the car park which is medium sized but can get busy on a weekend, if it is full you can go back out on to the (B6232) and turn left for a few hundred yards, before turning right into Clough Head car park. There is also a very good café and toilet facilities which makes for a good stop after your walk.

From the car park head through the metal gates which will lead you down towards the reservoir, after a few hundred yards you will have a choice of walking around either way. It is entirely up to you which you choose and either is no more difficult. At the south western end of the reservoir there is woodland you can choose to walk through which will bring you back out onto the main path. It is a great alternative and one I often take and have a few minutes forest bathing.

The woods feel very enchanting but unfortunately do not cater for wheelchair access. There is a small stream with a little waterfall which filters into the reservoir. On the northern side there are a few points of interest about the history of the valley and some old ruins too.

You can take as long as you like to do this circuit and in summer people often take picnics and just enjoy the beautiful surroundings.
