My Upcoming 14 day Itinerary for Trip to Ireland/Scotland

Night 4&5 in Killarney-you could also do Muckross House and there is a petting zoo there for the little ones. Lots of easy hikes/walks too around pretty lakes and waterfalls.
Night 11&12-don’t miss Cullodin Battlefield, which is very near to Inverness.
Have a great time!

Thank you Diveloonie. I will check both of those suggestions out. Definitely lacking for what to do in the Inverness region. Thanks again!

Have you also posted this in the Scotland forum? I'll comment on the Scotland portion in case you haven't.

Golf at St. Andrews: You are aware of the handicap requirement and the lottery system for tee times? There's plenty of other stuff to do in St. Andrews, such as the Old Course walking tour, the British Golf Museum, and playing the Himalayas (Ladies Putting Green -- if you're there on a day when it's open to the public). The town itself also has its charms, and the North Sea coast out toward Anstruther provides a lovely contrast to Scottish highland scenery.

From Inverness one day you could go west to Urquhart Castle and the Loch Ness Centre & Exhibition. The castle is a ruin, therefore dress for outdoors. It has walking tours several times a day and costumed interpreters. The Loch Ness Centre & Exhibition is an indoor experience, a fairly scientific (or at least fact-based) examination of "Nessie" sightings.

On your other Inverness day you could go east to Culloden Battlefield, Cawdor Castle, and Clava Cairns. The town of Nairn on the Moray Firth, just beyond Cawdor Castle, has a scenic marina and beach, and the restaurant The Classroom is excellent.

You never know about road detours or traffic tieups, so allow plenty of time to drive all the way from Inverness back to Edinburgh, turn in your car, go through security, and spend or exchange your last few British pounds.

Doable overall. If you are staying in a private home near Killarney it's fine, hope you aren't booked IN Killarney. The city itself is overloaded with tourists and tour buses, Holiday Inns and cheap ridiculous Leprechaun-y souvenirs shops. It's why Rick Steves put it on the Top Ten tourist traps in all of Europe. Avoid it if you can. If not too late Kenmare would give you a much more real Wild Ireland experience with plenty of pubs and restaurants and great music....and its right on and accessible to all the great sights NEAR Killarney and the south side of the Ring of Kerry.
Would skip the drive to Cork when there is a month's worth of things to see near where your staying. Molls Gap, Ladies View, Sneem, Staigue Ring Fort, the insane views near Caherdaniel, wonderful Waterville, the Skellig Ring (with no tour buses allowed), the Castle and Abbey Ruins at Ballinskellig, the gorgeous Glen, the Cliffs of Kerry...much more wild and beautiful than Moher, Portmagee and Skellig Michael and Valentia Island. All amazing and close by. Enjoy as much of that as you can. Much better than the Cork area and less driving to so more time to see this incredible area.

In Galway consider a fun day trip ferry ride to the Aran Islands, gorgeous and so fun. Pony cart or van around the island....especially see the amazing Dun Anghosa fort with cliffs FAR far more wild and dramatic than the tourist clogged cliffs of moher (which are beautiful just very touristy). Absurdly good soup and chowder at The Pub there too.
Also in Clare are the Cliffs of Kilkee - also far more wild and beautiful than Moher. Also a day in the idyllic and hauntingly beautiful Connemara is a great ride out from Galway city.
Have a great trip....very smart to stay in a few places longer and explore from there. Hope you can avoid staying in Killarney and skip Cork for more time on the ROK/Skellig Ring or even a foray onto Beara...you'll never regret seeing those sights. Keep driving to a realistic minimum and leave plenty of time for those magical moments discovering things on your own and interacting with the warm, funny, welcoming Irish people...those "little" moments and those amazing people are what turn a vacation itinerary excursion into a trip that will truly live in your soul ! Have fun !!!!

Thank you both for your suggestions. Yes, we are locked into our reservations for where we are staying each night but except for Dublin, we are staying outside these cities and towns in private residences we have rented. We felt like that experience would be so much better than staying in city hotels. When you have never traveled to a country before, it is so hard to figure out what to see, where to stay, etc. so it is great having those of you who have been fortunate to travel so much help with suggestions. We picked Killarney more for the location in respect to having a "base" to travel around from than planning to just visit Killarney itself. I definitely like the suggestion for Muckross House which I think our 2 little ones will enjoy (and us big kids too). Thanks again.

epltd: We have reservations already for St. Andrews (handicaps and all accounted for) as my husband is an avid golfer. This has been a lifelong dream of his to visit and play there so that was a "not miss" opportunity on this trip. While the guys are golfing I was thinking of taking the 2 girls to the zoo there in St. Andrews and maybe a walk along the beach unless any of you know of something they might enjoy more.
