Killarney, situated at the eastern end of the Reeks, is the nearest town of significant size and offers everything the hill walker requires; supermarkets, pubs, restaurants, hotels, guest houses, railway station, etc.
We took the car on the Fishguard to Rosslare ferry, sailing with Stena Line. Visit www.stenaline.co.uk to find out seasonal sailing times. This left us with a four and a half hour drive to Killarney which we broke with an overnight stop in a B&B just west of Cork.

The Tourist Route is said to be the easiest path to the roof of Ireland. It starts where the road ends at the mouth of Hags Glen (GR 837873), car park 2 euros. The path follows the Gaddagh River in a south westerly direction, passes between Lough Gouragh and Lough Callee before tackling the step scree slopes of the Devil's Ladder. Upon reaching col in the ridge line of the Reeks, the path follows the ridge north westerly to the summit. Decent is usually by the same path.
The Coomloughra or Carrauntoohil Horseshoe offers a circular route taking in the summits of Caher, Carrauntoohil, and Beenkeragh, see text. We started by the shores of Lough Acoose, but you are better served starting the ascent by taking the rocky track up to Lough Eighter (GR 772871). There is parking off the road further south. It does not make any difference in the direction the horseshoe is tackled, however we chose to leave Beenkeragh until last. The thinking behind this was to leaving the most difficult section until last so that failure here did not prevent us from summiting the big one.
A Traverse of the Macgillicuddy's Reeks offers the ultimate day on these mountains but is only for the fit. The route takes in eight Munros (peaks over 3000 ft), starting from the car park at Kate Kearney's Cottage north of the Gap of Dunloe (GR 881890), and follows the ridge line westwards to Lough Acoose. For more details on this route take a look at "The Big Walks" complied by Ken Wilson and Richard Gilbert.
There is plentiful accommodation in Killarney and in private bed and breakfast all around the Reeks. Start by visiting the Irish Tourist Board Website.
Youth Hostels offer a good option for those travelling on a tight budget. Visit the Irish Youth Hostal Association website.
There are no mountain huts in the Reeks.
The best map I could locate was Number 78 of the Discovery Series published by the Ordnance Survey of Ireland, 1:50,000.
The Big Walks compiled by Ken Wilson and Richard Gilbert, and published by Diadem is a classic guide to the best Challenging Mountain Walks and Scrambles in the British Isles. Route 54 covers the Macgillicuddy Reeks and has excellent photos.
As one would expect, the Irish Tourist Board Website has useful fact about travelling to Ireland, including accomodation, events, etc.
The area protected by the Killarney National Park does not cover Reeks, but their wibsite is worth a quick visit.
