Ladies View is on the way from Killarney to Kenmare. Gap of Dunloe is not on the way - you would either have to head back to Kate Kearney's Cottage and get a Jaunnting car to the Gap or drive up to the turn off for Kenmare and then down the Black Valley and drive through. Not a drive for the faint hearted and it would take you 2 hours or so, and then you'd be back at Kate Kearney's cottage again!!

My suggestions, for what its worth (get out a map of Ireland if you have one and look at the locations)

Muckross House and Gardens or merely the Gardens if you wish. I love the gardens.

Torc Waterfall. Not too far down the road from Muckross. Its about 1/4 mile walk or so from the road.

Ladies View.

The scenery from Killarney to Kenmare is magnificent. So pull in where its safe.

Kenmare.

Then you have a choice:

Inland to Gougane Barra cork-guide.ie/gouganebarra/gouganebarra.html

OR and this will take a bit longer, drive to Glengarriff and along parts of the coast (don't go out to the headlands)
