A pleasant 2 hour walk from Roundstone village by taking a minor road to the west from the centre of the village. There is parking along this road at L71775 40102 A. Continue on ungraded road to a wooden gate at L71295 40206 B giving access to the open hillside. Summit area has a trig point and a second 'high point' with a cairn.
Also possible to park on the R341 at L68279 39762 C and follow a bog road leading North before heading to the summit Linkback: https://mountainviews.ie/summit/957/comment/16111/

Errisbeg is an unremarkable looking hill from any angle, but the views of Dogs Bay, Inishnee and most of all the Twelve Pins are truly outstanding on a good day. I have walked it a couple of times, on both occasions from Roundstone. At the harbour, turn up the road at O'Dowds pub and restaurant -well worth a visit for a pint and food on the way back. Just follow this road until a gate next to a house is reached and this leads on to the open hillside. It is then just picking a route and keeping the top visible where possible, as it is easy to meander a bit with the constant changes in the terrain from rocks to grass and heather. The view opens up very quickly so the ascent is always enjoyable in good conditions. An easy to moderate walk, and you can be up and down within three hours or so. You will probably want to linger for the stunnng Connemara views on a half-decent day though. Linkback: https://mountainviews.ie/summit/957/comment/22722/

Errisbeg is indeed a wee cracker. In not too much more time than Simon suggests, you can traverse it West to East dropping down into Roundstone, have a couple of pints and some prawns, stop for a swim at Dog's Bay and walk back along the road to your car. Or, if the road looks too long or too busy, have a bike stashed and send the most energetic member of the party to retrieve it.

But I'm waiting for screams of rage from pedantic geographers at the transfer of this hill to the Twelve Pins (or 12.5 Pins as they'll certainly have to be renamed.) The photy is of the distant Pins from Roundstone at the foot of Errisbeg. Linkback: https://mountainviews.ie/summit/957/comment/3272/

Errisbeg has fine views over the intricate patchwork of water and land that is Roundstone Bog to its north. One way of getting up it is to start to its southwest at L 68279 39762 C, which is reached by going west out of Roundstone past its slopes and parking beside the road. A bog road leads north from around there.

At an admitedly fairly leisurely place it took our party over 4 hours to get up and down over the distance of only 4.8k there and back. So we found the walk surprisingly time-consuming for such a small height gain. The land is extremely rough in places.

Another wonderful day with the weather here and it was the ideal day to hike to the summit of Errisbeg in Roundstone. I was pleasantly surprised how quickly I got to the summit, I thought it would take longer today but not the case. It was well under an hour. I had a wonderful snack whilst gazing down at such scenery.

The scenery is just stunning and the elevated views of Dog's Bay Beach are nothing short of astounding. Great to see some other hikers out and about this afternoon and there are many large rocks at the top to sit down and gaze and this wonderful picture-postcard setting. I could even see portions of the Lower Sky Road today in the distance. Linkback: https://mountainviews.ie/summit/957/comment/20324/

Access to this hill is from a farm trail on the West side heading along the R341 at L68410 39753 D. After following the track for a few hundred meters at L68095 40424 E, it's a matter of simply picking your route to the East up the open hillside to the trig point at 300 metres. As Errisbeg is so far removed to the West of the other peaks in Connemara, the views back over to them are great. And as for the views of the beaches below to the South......
