Originally this lake was known as Broadwater but has been known by the name of the valley for many years. It is approximately two and a half by three quarters of a mile. The River Liza flows down from Great Gable, through the Liza Valley, into the lake. Great Gable’s northern crags face down the valley, next to Kirk Fell. Pillar Rock is here too, a favourite with rock climbers although once believed to be inaccessible. There is a wild beauty here, only slightly modified by the afforestation in the area.
Ennerdale Bridge is the village from which the lake is usually approached. This lies about a mile to the west of the lake. Another route, avoiding the village is from Rowrah or Lamplugh by Croasdale. There are various footpaths and fell walks around Ennerdale Water. A couple of car parks are close to the lake and there are several picnic areas here.
