About Yarlside
Yarlside is one of the Howgill Fells, in what is now Westmorland and Furness but historically Westmorland, and lies within the Yorkshire Dales National Park. It rises to just over 639 m and is a Hewitt, Nuttall, Marilyn and Simm.
The name causes confusion elsewhere in the region. A separate Yarlside near Barrow-in-Furness, once served by the Yarlside Iron Mines tramway, lies about 53 km west, and Great Yarlside and Little Yarlside sit some 18 km north-west on the eastern edge of the Lake District.

The Yarlside group
One other listed summit sits in the same prominence group, with Yarlside as the independent hill at its head.
| Summit | Height | Drop |
|---|---|---|
| Randygill Top | 624 m | 133 m |
Grouping is by prominence alone: a summit belongs to the nearest higher Marilyn it connects to without a deeper intervening col. Over a large massif that can gather hills no one would walk in a single day, and which few would describe as parts of the same mountain — it is a measure of independence, not a suggested route.
