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/
