In my opinion if you only had a couple of hours to spend in Kilarney, I would suggest going to the Muckross Estate which comprises heaps of attractions within it's grounds like a lovely Victorian fairytale manor where Queen Victoria slept ($ fee), fabulous English Gardens (free) a Traditional Farm attraction ( $fee) an abbey (free) and info about Killarney National Park. W.B Yeats apparently also loved this place so much, he visited and stayed here a couple of times.
I only went around the house and the external gardens, and then did the 1k walk from the house to the abbey. The grounds are so so so lovely - beautiful rock garden, lovely streams, gorgeous flowers, and towering ancient trees with gnarled trunks all situated alongside a lovely lake and as far as your eye spans, you can see the mountains that form the Ring of Kerry.
Some places are breath-giving and precious, and that's what Muckross is to me. Even if you don't actually go into the house, just wander to the ticket office and scroll thru the books they have there, to get an idea about the tragedy and generosity thru which the house and grounds became part of Ireland's first national park system as well as the links it has to that famous painter, Mary Herbert who lived here.
Frankly with the free parking, this place is an absolute steal! And yeah, if I was a local, I would absolutely be visiting here frequently and recommend it whole-heartedly. A +++
