We wanted to spend sometime in the area around Kilarney and the town itself. Our hotel was perfectly situated for that. Situated a few kilometers outside the city; probably about 5 mins worth of a drive to the public parking in Killarney.
Ross castle (very nice cafe actually), nice boat ride in the lake, visit to the Muckross Victorian mansion, ladies view, the Torc falls, the Gap of Dunloe the drive from one spot to the next... All beautiful in their own way and worthwhile the visit. One should probably allocate 3-4 days to go through all that without rushing it. We've found that you need to take your time to actually take in the natural beauty of some of these places.
