River Derreen — a spot well known among anglers. About 67 km long. Here you'll find a bite prediction — when fish are active and which hours give the best chances, adjusted for weather and pressure. The river runs through County Carlow and County Wicklow — the bite forecast is computed for each stretch separately, from the weather of its own region.
