Mweelrea

Mweelrea is a mountain summit in the Connacht region of western Ireland, reaching 814 meters above sea level with steep slopes on multiple sides. Views from the top take in Killary Harbour and Doolough Pass, with broad valleys stretching below.

The mountain took its current form during the Ordovician period hundreds of millions of years ago, shaped by sandstone deposits and ancient river sediments. These geological processes carved out the landscape visitors see today.

The Irish name means 'bald hill with the smooth top', a description locals still use today when talking about this mountain.

Climbs usually start from the Delphi Adventure Centre, with trails following the Owenaglough River through forested sections and then open grassland. Visitors should be prepared for changing weather conditions typical of Irish mountains.

Two natural lakes sit in mountain hollows on the peak area: Lough Lugaloughan and Lough Bellawaum, carved by ancient glaciers. These lakes create striking features that catch the eye from many angles.
