Lough Mask is a very large lake that spans the Counties of Mayo and Galway. It is actually the middle of the three lakes, which all empty into the Corrib River. And the view from up here is delighful.

Whether you're looking west toward Lough Nadirkmore, or east to the much bigger Lough Mask, you're surrounded by wonderful views of water. Lucky you!

A lough surrounded by peaks is a wonderful thing. Enjoy a rest by Lough Nadirkmore after the short but relatively steep climb. If the weather is with you, there aren't many better places in Ireland for a wild swim.

Cloghbrack Far is one of the lesser taken paths up Nephin, but it's well worth your time. It's a consistently steep ascent, so perfect for experienced hikers looking to challenge themselves. The views are worth the climb though.

The southern side of Nephin is perhaps less popular than the northern trail, but it's worth seeking out. A steep but relatively consistent gradient makes this a tough but easy to navigate climb.

The climb up to Nephin is well worth the effort, whichever path you take. Enjoy the panoramic view from Ireland's highest standalone mountain.

It's a wonder Nephin Mór isn't called the "Giant of Connacht". The highest stand alone mountain in Ireland and the second-highest mountain in Connacht, it is Ireland's Mont Ventoux. Well, maybe not exactly the same, but you can see the peak for the majority of the hike, as here at around the halfway point. The hike is well marked and the path is clear.
