The Liffey and the Slaney rivers rise in Wicklow, and there are lakes and picturesque glens. Sheep and cattle are raised in the region, and grains are cultivated. Wicklow also has copper mines and a hydroelectric plant has been constructed in the area. Its proximity to Dublin makes the region a popular one with tourists.
