High Arnside Tarn is a little jewel. This one and half acre tarn nestles unseen just off the busy footpath from High Arnside tarn to Tarn Hows, about a mile past Skelwith Bridge on the A595 Coniston Road. The water is 15 minutes walk from the road.
High Arnside holds a stock of wild browns which the Association supplements annually with brown trout averaging 1.25lbs. This is very much a water for the careful imitative angler with small nymphs and dries giving the best results. The trout patrol the shoreline and weedbeds and it can pay to stalk individual fish rather than fish the water blind.
Later in the season weed can be a problem but there are still enough gaps for entertaining sport. The water is not heavily fished. As a beautiful place to spend a couple of hours in the evening or as a change from the busier rainbow trout fisheries – it is hard to beat.
Day permits are available for the tarn which is included in WADAA’s Wild Trout Water permit. The bag limit is two fish, barbless hooks are preferred and the season runs from 15th March to 30th September. April, May, June and September are the best months.
