Recently, I received a thoughtful gift of the book ‘Irish Peaks’. Produced by Mountaineering Ireland, this magnificent printed work provides 72 suggested routes encompassing some of Ireland’s highest mountains. I have bagged many of the summits recommended for Leinster such as Kippure, Lugnaquila and Mount Leinster. However, one option that I hadn’t completed stood out to me straight away – Seefingan. This article gives a detailed account of the Seefingan hike via the Seefin Passage Tomb.
Seefingan stands at 723m which makes it the 43rd highest mountain in Ireland. Seefingan is the 10th highest mountain in Leinster. I found this a lovely walk to the top of Seefingan. However the highlight for me is the passage tomb located at the summit of the smaller Seefin Mountain (621m) on the way to Seefingan.
Seefingan Hike Details
- Distance: 8.2km
- Time Required: 2.5 hours
- Elevation Gain: 460m
- Grade: Moderate Difficulty. The ascent is gradual enough with some steep climbing on the approach to Seefin. The trail from Seefin to Seefingan is extremely boggy which can be draining on the legs.
- Starting Point: Entrance to the forestry maintenance road at Athdown. See link to google map here.
Getting to the Start of the Seefingan Hike
Unfortunately, the only option to get to the starting point is to drive as there are no public transport links to this part of rural Wicklow. Parking spaces at the starting point are limited. However, it’s very possible you will have the whole mountain to yourself so this shouldn’t be an issue. The barrier gate was open when I arrived so I chanced parking inside the entrance. I couldn’t see any indication of opening or closing times so this was a risky move on my park. Luckily, it all worked out.
If you don’t drive, Hilltoptreks.com offer guided walks taking in these summits with pick-up and collection from more accessible locations. Prices quoted by them at the time of writing was €25 per person.
If you need to hire a car, rentalcars.com is a good comparison site. Day rentals can be found here.
Route for the Seefingan Hike via Seefin
I find that alltrails.com is a good source for maps of hiking routes in Ireland. The map located here shows the full Seefingan Hike route. The trail moves up through Athdown Forest before skirting along the edge of wood and looking out over the Liffey Valley. Thereafter the path moves through thick gorse to the top of Seefin. From Seefin, you trek across the bog to Seefingan. Then back the way you came with a slightly different route back through the forest.

Starting the Seefingan Hike
I set out from the start point at 11a.m. on a blustery Tuesday morning. While there were clouds overhead, the wind was moving them along quickly and the forecast was good for the afternoon.
Essentially I took a right turn after going through the gateway and moved uphill along the roadway. Already, I had nice view to my right and across the Wicklow Mountains.


I followed the road for nearly a kilometre. With the treeline to my left I climbed up an earthen path for a short stretch before turning left and back on to a road again. I noticed this road as being less well maintained as the previous one as I moved along it.


Through Athdown Woods
Three deer crossed the road a couple of hundred metres in front of me. They glanced at me curiously before heading downhill and into the trees.
The road ended at the 1.7km mark. The end of the road is marked by a small turning circle. I needed to keep going straight and onto a well defined if narrow pathway through the trees.

After 100m or so, I came to the end of the woods. As I came to the end of the treeline, I enjoyed wonderful views out over the Liffey valley with Poulaphouca Reservoir visible in the distance.

Upwards Towards Seefin
I found the next 500m or so the steepest part of the Seefingan hike. I moved slowly upwards keeping the trees on my right and a fence on my left. When the fence ended, the most direct route to the Seefin is to keep going straight up. Alternatively you could go right here and then take a left uphill after 100m or so.

I went straight up. While a little difficult initially to see where exactly the path follows, I noticed it became more apparent quite quickly.


The earthen path broadens out to a grassy bank on the approach to Seefin tomb.

Seefin Tomb
The tomb itself dates back to c. 3,500 BC. I always find it amazing to be so close to these historic monuments. I’ve written previously about the almost mystical feeling when I visited Loughcrew. Being on my own at Seefin Tomb felt similar. I think the solitary aspect adds to this. I had climbed the mountain and the only living creatures I had seen were a few deer. Now, here I was at the top beside this impressive national monument. The entrance to the passage tomb faces north and interestingly in the direction of the more famous similar type monuments in Newgrange and Knowth.



Across to Seefingan
The next part of the Seefingan hike is less enjoyable. The summit of Seefingan is clearly visible from Seefin. For most of the year, conditions underfoot will be extremely soft and mucky. Indeed, during the winter months, I would not recommend crossing this bog land at all.

I completed the energy sapping trek across the valley and up to Seefingan as quickly as I could. Along the way, I still managed to enjoy some lovely views.

To my left was the Kilbride Rifle Range. It goes within saying to avoid going near the range.
It took me about 25 minutes to summit Seefingan from Seefin. Another burial cairn sits near the top of Seefingan. I had my lunch at the top and admired the views. To the north Dublin City can be seen on clear days. To the south east is Kippure – the highest point in County Dublin.


The Return Journey
I retraced my steps and moved back towards Seefin. On the way down after Seefin, I took a more direct route to get down through Athdown Woods. About 300m downhill from Seefin tomb, I took the left option when coming to a fork in the path. Going right would bring me back the way I came up.

After taking the left option, I moved in pretty much a straight line down the hill.


The path brought me back to the forestry maintenance road I used earlier. From there, I followed the road downhill and back to my car. Thankfully, the entrance gate was still open!
Overall, it took me just under 2.5 hours to complete the Seefingan Hike via Seefin. That includes stopping for a quick lunch. The hike itself is nice and offers up some lovely views along the way. As mentioned above though, the real highlight is the Seefin Passage Tomb.
