Hello again, Robin! :)
You won't have to wait much longer now, and 10 days is a wonderful amount of time to explore the island. I think it's a great idea to take your time, but still try and see as much as possible in those two days.
So I've collected a few suggestions for you per day:
Day 1:Since you're in Killarney National Park, check out
Muckross House as well if you have the time. Killarney itself is filled with wonderful and musical pubs, and I highly recommend a trip to
Laurels Pub. They host regular live Irish music/dance nights, so if you’re looking for some entertainment here, you won’t be disappointed. Another traditional pub with great musicians is
Murphy's, and on top of that they also serve lovely food! My last recommendation is
Courtney's Bar, which has been a public house since the 1800's, and is super cosy.
Day 2:
The drive from Killarney, via the Gap of Dunloe, on to Portmagee will take around 1,5 hours, but I'd recommend to take some time for stops and photo moments along the way. The Skellig Eco Tour departs from Portmagee Marina, and there are several tours available during the day. I would recommend
booking your tour beforehand, just so you'll have everything sorted for that day. The tour does indeed take around 2,5 hours, and from there on you'll have time to explore the area. Is there anything else that's not on your list, but that you would like to see?
Your first day is a fun and packed day indeed, with lots of things to see and do. What do you have planned for the next day?
