Newark Castle, Newark Hill, Fastheugh Hill and Howe Bottom Loop

This medium-rated loop of about 13 km / 8.1 miles with roughly 400 m / 1,310 ft of ascent explores the rolling hills and estate landscapes west of Selkirk, combining a ruined Border stronghold, broad ridge walking, forestry edges, and open views over the Yarrow valley. The route is generally best suited to hikers with a reasonable level of fitness who are comfortable with a few sustained climbs rather than technical ground. Newark Castle lies in the Bowhill estate area near Selkirk, with the nearest practical landmark and access point being Bowhill House, Bowhill, Selkirk TD7 5ET, a useful reference for sat nav and journey planning.

The walk typically begins near Newark Castle on the Bowhill estate side of the Yarrow valley, a few miles west of Selkirk. Early on, expect estate tracks, woodland margins, and a steady build toward the higher ground around Newark Hill and Fastheugh Hill. Fastheugh Hill rises to about 502 m / 1,647 ft, so although this is not a mountain day by Highland standards, it is high enough to feel exposed in wind, rain, or low cloud. The climbing is spread through the route rather than concentrated in one single pull, but the uphill sections can still feel demanding when the ground is wet or soft. (mapcarta.com)

Terrain and what to expect

The first part of the loop is usually the gentlest underfoot, with estate roads or clearer paths leading toward the castle and lower slopes. As the route gains height onto Newark Hill and then toward Fastheugh Hill, the character becomes more open and more obviously upland. Expect grassy tracks, moorland paths, and potentially muddy or indistinct sections, especially after rain. In places, route-finding may become less obvious than it is near the estate, so carrying offline mapping in HiiKER is a sensible precaution. Because the hills here are rounded rather than craggy, poor visibility can make direction more awkward than the terrain first suggests. (sobt.co.uk)

The ridge and upper slopes are where the walk earns its “medium” rating. Around the halfway point, the route’s cumulative ascent begins to show, and the more open ground can be fully exposed to Border weather. Strong winds are one of the main things to watch for here. Even on a relatively short loop, conditions can change quickly, and the tops can feel much colder than the sheltered start near the estate. Waterproof layers, an insulating layer, and footwear with decent grip are worth treating as standard kit rather than optional extras.

The descent by Howe Bottom brings a change of mood. This area is associated with woodland and lower valley ground west of Selkirk, so the latter stages often feel more enclosed and quieter after the open ridge. Descents on grassy or forestry-side tracks can be slippery, particularly where leaf litter, wet grass, or churned mud build up. Trekking poles can be useful if knees are sensitive on the way down.

Landmarks, scenery, and historical interest

Newark Castle is the standout historic feature and gives the walk much of its identity. The ruin stands above the Yarrow Water in the grounds of Bowhill and dates to the 15th century, built by the powerful Douglas family. It later passed to the Crown after the fall of the Black Douglases, was besieged by English forces in 1547, and burned in 1548. The castle also has associations with the turbulent wars of the 17th century, reflecting just how contested and violent the Scottish Borders once were. (castleuk.net)

This is classic Borders country: rounded hills, river valleys, estate woodland, and long pastoral views rather than dramatic rock architecture. From the higher sections near Newark Hill and Fastheugh Hill, you can expect wide outlooks across the Yarrow and Ettrick landscapes, with the folds of the Southern Uplands stretching away in soft layers. The scenery is especially appealing in mixed weather, when sunlight moves across the hills and picks out the patchwork of pasture, heather, and forestry. Bowhill’s designed landscape also adds a more cultivated element to the route, blending historic estate planting with the surrounding uplands. (scotborders.gov.uk
