The OSI Discovery Series, sheet 74 is all you need to tackle this mountain.

4. Lugnaquilla

Location: Co. Wicklow
Coordinates: 52.966619, -6.462914

Height: 925m

Difficulty: Difficult

Lugnaquilla is located in Co. Wicklow and is the highest mountain in Ireland, outside of Kerry. The mountain’s proximity to Dublin, make it an ideal climb for any adventure tourists visiting the capital or Dublin residents looking for a change of scenery in their leisure time.

Described as a gentle mountain with a mean streak, climbers shouldn’t underestimate how strenuous a climb Lugnaquilla is. An open mountain, much of the trail is exposed to the elements, meaning suitable outdoor clothing is paramount. There’s lots of exposed mountain trail underfoot and no markings to the summit, meaning caution is advised.

With such a tricky climb, make sure to have the OSI Discovery Series, sheet 56 to hand. The perfect accompaniment to any Wicklow walks.

3. Mount Brandon

Height: 951m

Difficulty: Strenuous

Measuring 951m in height, Mount Brandon is the highest peak outside of the Macgillycuddy Reeks. Steeped in Irish mythology and folklore, the mountain was a pilgrimage site in pre-Christian times. Being the highest and most westerly summit in Ireland, Mount Brandon was the last place to see the sun set, making it particularly important in Pagan beliefs.

Today, the mountain is best known for its association with Saint Brendan – who some believe discovered America before Columbus. The mountain’s pilgrimage route, Cosán na Naomh, is extremely popular with walkers and pilgrims alike.

Upon reaching the summit, walkers are greeted with stunning views of the Blasket Islands and Dingle peninsula – weather permitting of course.
