The Three Brethren loop from Three Brethren Carpark

The trail officially starts from the Three Brethren Carpark in Roxburghshire. This is the primary access point, and parking is available there.

The terrain is varied, featuring good hill tracks and wide paths, but some sections on the return route can be less well-trodden. Expect a mix of forestry paths, heather-lined sections, and open hillside. You'll encounter grass, drystone walls, and exposed moorland. Be prepared for potentially wet and boggy ground, especially near Linglie Burn or after rain, as parts can be muddy or eroded. Sturdy boots are highly recommended.

This loop is generally rated as moderate. While it features steady gradients for the most part, there are some strenuous climbs, particularly to reach the Three Brethren. Hikers should have a reasonable level of fitness. The distance is around 9.6 km (6 miles), and it can take 2.5 to 5 hours to complete, depending on your pace and specific route variations.

The trail offers excellent panoramic views over the rolling Borders hills. Key landmarks include the View of the Three Brethren themselves, which are massive, historic cairns. You'll also pass Red Score Nick Pass and enjoy a View of Linglie Hill and Selkirk. Other scenic elements include a burn in a ravine with glimpses of the Corbie Linn waterfall, a reservoir, and views of the Eildon Hills and Yair Hill Forest.

Yes, the trail is generally dog-friendly. However, as it passes through open hillside and potentially near livestock, it's advisable to keep dogs on a lead, especially during lambing season or when sheep are present. Always follow the Scottish Outdoor Access Code.

No, there are no permits or entrance fees required to hike the Three Brethren loop. Access to the trail and parking at the Three Brethren Carpark is free.

The trail can be enjoyed year-round, but spring and autumn offer pleasant temperatures and beautiful scenery, with purple heather in late summer/early autumn. Be aware that conditions can be wet and boggy after rain, and winter hikes may encounter snow and ice, requiring appropriate gear and experience. Always check the weather forecast before you go.

Yes, the route intersects with several other paths. It forms part of the Southern Upland Way (Section A - Portpatrick to Melrose) for about 22% of its length and also follows an old drove road known as the Minch Moor. Additionally, sections of the Capital Trail (31%), Corbie Linn Road (45%), Three Brethern Descent (26%), and Rocky Road (5%) are part of or intersect with this loop.

Given the varied terrain and potential for wet conditions, sturdy hiking boots are essential. Waterproof and windproof layers are advisable due to exposed sections. Bring a map and compass or a reliable GPS device, as some parts of the return route can be less well-trodden. Water, snacks, and sun protection are also recommended.

The Three Brethren Carpark itself is a basic trailhead with parking. There are no immediate facilities like toilets, cafes, or shops directly at the trailhead. For amenities such as cafes, pubs, or accommodation, you would need to visit nearby towns like Selkirk.

Public transport options directly to the Three Brethren Carpark are limited. It is primarily accessed by car. For those relying on public transport, reaching a nearby town like Selkirk by bus and then arranging further transport or a longer walk would be necessary.
