Beinn Tarsuinn

Beinn Tarsuinn, at 936-937 metres — "the Transverse Hill" — is one of the remotest Munros in Scotland, its summit featuring stunning rock architecture including a curious square, tilted platform on its western ridge that has been likened to a tennis court.

Reached from Mullach Coire Mhic Fhearchair as part of the classic Fisherfield Round, the connecting ridge crosses a col before a path traverses below Meall Garbh, leading to a broad bealach and up open, grassy slopes — the mountain is quite undistinguished on this approach, but everything changes on reaching the summit cairn, with a great view over the west ridge's curious tilted platform. Beyond the plateau, the ridge narrows into a series of pinnacles, though the standard route branches off before this point, descending the hillside towards A' Mhaighdean.

An alternative approach from the south, via Incheril and Lochan Fada, gives easy walking initially before becoming progressively rougher on largely grassy slopes leading to the summit, with a broad bealach between Meall Garbh and Beinn Tarsuinn to cross first.

From the summit, the descent towards A' Mhaighdean crosses an extensive, very boggy bealach — the lowest point of the full Fisherfield Round at around 525 metres — followed by a long, grinding pull up broad, grassy slopes to reach what's often regarded as the finest Munro summit view in Scotland.

The full Fisherfield Round taking in all five Munros from Corrie Hallie is a genuinely epic undertaking, typically requiring an overnight stay at Shenavall bothy or a wild camp, with total distances covering around 27 miles and 8,800 feet of ascent.

The initial descent from Mullach Coire Mhic Fhearchair over quartzite blocks demands care, particularly in wet conditions, and the broad bealach crossings on either side of Beinn Tarsuinn can become genuinely boggy — full navigation and self-sufficiency are essential given the remoteness of this whole area.

There is no direct parking at the mountain itself; Corrie Hallie or Incheril car parks serve as the main starting points, both free, with limited public transport connections.
