Arnsbarrow Tarn is a small, almost circular tarn, located in the undulating fells between Coniston Water and Grizedale Forest. It sits at the head of Tarn Beck, surrounded by three summits - Top o'Selside to the west, Heel Toe Hill to the north and Arnsbarrow Hill to the south. A right of way between Top o' Selside and Arnsbarrow Hill runs past the tarn, but wasn't that easy to spot on the ground on my last visit to the area.
The name implies that there was once a barrow or a stronghold of some sort in the area (Arne's Barrow), but there are no recorded barrows in the area.

How to Reach
Arnsbarrow Tarn can be reached from Grizedale by following the route to Top o'Selside at our sister site Storm-Crow, then heading east from the summit.
From the Coniston side take the track that runs from High Nibthwaite (at the foot of the lake) up towards Low and High Parkamoor. Turn east when level with Top o' Selside, and approach the tarn over the top of the fell (recommended for the views).
None of our walks visit Arnsbarrow Tarn.
No becks flow into the tarn
Tarn Beck drains the tarn, running south-west to join Selside Beck, which then flows west into Coniston Water.
