This was a short, family walk starting from Skelwith Bridge. We parked on the road near the Skelwith Bridge Hotel and roughly followed the route to Loughrigg Tarn from the Jarrold Lake District Short Walks book. After a short ascent through a holiday park of wooden chalets, the route around the tarn is quite clear and largely flat. There is a small stream into the tarn which can be jumped or crossed by stepping stones.
The circuit is under 3 miles, so is a handy short walk if you need to fill in an hour or so.
