I've also written several blog posts about Killarney PP here, here, here, and here.....so many blogs posts that you might get the impression that I really liked Killarney PP. I did. Killarney is very unique, gorgeous, and I got a lot of great photos, albeit in no small part because I was able to arrange a flight to do aerial photography.
Even though the elevation gains are pretty reasonable (up to 1000'), it is much rougher hiking than western parks due to the nature of the trails (not well benched), the constant up and down, the average grades (can be very high), and the very, very slippery nature of the rocks when wet. This is a park, for me at least, that is much better suited for day hiking when I can choose the dry days. I would not want to be doing anything vertical in this park when the rocks are wet or when there is rain forecast.
Here are some of my favorite photos from my Killarney hikes:
