Overview
Seefin is a striking summit in the Wicklow Mountains, rising to roughly 621 m (some sources list 650 m) and overlooking the Glenasmole Valley. At its crown lies the Seefin Passage Tomb, a megalithic monument dating to around 3,500 BC. The site is steeped in myth – its Irish name Suí Finn means “Finn’s Seat”, referring to the legendary hunter‑warrior Fionn mac Cumhaill of the Fianna. The tomb’s north‑facing entrance points toward the more famous passage tombs of Newgrange and Knowth, reinforcing its place in Ireland’s ancient ceremonial landscape.
History & Significance
The Seefin Passage Tomb is a cruciform, stone‑built structure shrouded beneath a mound of cairn material. Its corbelled roof is incomplete, allowing a glimpse of the interior chambers. Archaeologists note two side chambers and a rear chamber, though excavations in 1931 by Professor McAllister found no burial artefacts. Decorative motifs on some passage stones hint at a sophisticated Neolithic culture. Oral tradition describes passage tombs as portals to the Otherworld, and Seefin’s lofty position – overlooking the hunting grounds of the Fianna – reinforces its mythic aura.
What to See & Do
- Seefin Passage Tomb – Approach the monument from the north‑east and view the narrow stone doorway framed by two massive lintels. The external view is the only access permitted; the interior is closed to the public to protect the fragile structure.
- Panoramic Vistas – From the summit you can see the Liffey Valley, Poulaphouca Reservoir, and, on exceptionally clear days, the Dublin cityscape to the north and the peaks of Kippure and Lugnaquilla to the south‑west.
- Wildlife Encounters – The ascent passes through Athdown Forest, where deer are often sighted. The open heathland near the tomb is a haven for birds and native flora.
- Extended Loop – Many walkers combine Seefin with the neighbouring peaks of Seefingan (723 m) and Kippure (748 m) on a 21 km loop that takes roughly five hours. The route traverses mixed woodland, boggy plateaux and ridge‑top scrubs, offering varied terrain and rewarding views at each turn.

Seasonal Tips
Winter months can make the bog between Seefin and Seefingan very soft, increasing the risk of slipping or getting stuck. Many walkers postpone the full loop until late spring or early autumn when the ground is firmer and the chances of clear, panoramic views are higher.
