If you have just one day to plan an excursion/day trip during your stay in Killarney, do this one!
We did the trip the opposite way around from advertised, which confused me momentarily, but I don't think it matters which way round it runs, you won't miss anything.
The boat trip was magical (even in the light rain at the start) and the jaunting cart from Lord Brandon's cottage, up through the Gap of Dunloe to Kate Kearney's cottage, was a thoroughly enjoyable experience.
And to top it off the Deros' driver dropped me off right outside my hotel
Thank you Deros Tours for a wonderful day out
Don't be afraid to haggle the price a little with the Jaunting Cars
