Seskin [An Seisceann]

About Seskin [An Seisceann]

Sitting on the border between Wicklow and Carlow, this prominent Marilyn rises above Coolkenna Street. While its 344m summit is modest, it offers a clear vantage point over the Derreen River valley. On clear days, the jagged profile of Lugnaquilla dominates the northern horizon, while Mount Leinster stands tall to the south.

Did You Know?

• •The name Seskin is an anglicisation of the Irish An Seisceann, which translates as 'the marsh' or 'the fen,' likely referring to the poorly drained land found on the hill’s lower slopes.
• •Despite its relatively low altitude, the hill's prominence of over 150 metres earns it Marilyn status, making it a significant landmark on the southern fringes of the Wicklow Mountains.
• •The summit provides a grandstand view of the neighbouring Blackstairs Mountains, with the distinctive telecommunications mast on Mount Leinster clearly visible across the Carlow border.
• •Given the name’s origin, visitors should probably expect that the local drainage hasn't improved much since the hill was first named in Irish.
