Sawel Mountain

Sawel is the highest of the Sperrins at 678 metres, a broad whaleback of blanket bog and heather straddling the Derry and Tyrone border above the lovely Glenelly valley. It is remote, empty and quiet, which makes it a wonderful place to fly if you are prepared for genuine mountain conditions. Most pilots park on the high mountain road that crosses the shoulder to the south and either fly from the verge or make the boggy walk up toward the trig pillar. From height the drone reveals the vast rolling sweep of the Sperrin plateau, the deep green thread of Glenelly below, and, on the clearest days, views stretching to Lough Neagh, the north coast and Donegal. This is open upland with no obstacles, but the flip side is exposure: wind at the summit is often far stronger than in the glen, cloud can drop without warning, and there is no shelter or quick recovery if things go wrong, so treat battery and weather margins seriously. The ground is protected ASSI, and ground-nesting birds like grouse and curlew breed here in spring, so avoid low disturbance in the nesting season. Snow-dusted winter days give the most dramatic results, with the whole range thrown into sharp relief.
