The Vartry system in County Wicklow offers a diverse and historic angling experience, centered around a major reservoir complex and the river that flows from it. The headwaters rise on the slopes of Djouce Mountain and White Hill, with tributaries from Calary Bog under the Great Sugar Loaf, combining to feed the Vartry Upper and Lower Reservoirs. These man-made lakes, completed in 1865, are a crucial water supply for Dublin and form the heart of the fishery. From the reservoirs, the river flows eastward through the scenic Devil's Glen, past Ashford, under the N11 road, and continues as the Leitrim River through Wicklow Town before entering the sea at Wicklow Harbour and Broad Lough. The catchment covers approximately 122 square kilometers, presenting anglers with both stillwater and riverine environments.
