Main image

Sawel Mountain (Slieve Sawel) is a peak in Northern Ireland and the highest point of the Sperrin Mountains, with an elevation of about 678 metres. It is a prominent upland landmark for the region.

Hillwalkers use paths and open heathland to reach the summit; the mountain offers moorland scenery and views over the surrounding Sperrins. Routes are typically day hikes across boggy and peaty terrain, so boots and weather-appropriate gear are advisable.

The mountain has no significant built structures but has long been part of local upland grazing and recreational use. It features typical upland vegetation and landscape shaped by long-term pastoral activity rather than recent development.

Sawel sits on the upland spine of the Sperrin Mountains in Northern Ireland, near the border between County Londonderry and County Tyrone. It overlooks broad peatlands and ridges characteristic of the Sperrins.

  • Height and prominence: At 678 metres above sea level it is the highest peak in the Sperrin Mountains and a common objective for day hikes and ridge walks in Northern Ireland.
