Its less than a 5 minute walk from the parking lot to the waterfall! Beautiful spot, and is great for hiking if you are up for going up steep steps.
This is a 2-3 minute drive from town, has a big parking lot and is situated on one of the lakes.
This is one of the best activities to do on a sunny day in Killarney. There are plenty of bike paths and many different routes to take around the lakes and national parks. There are many places to rent bikes but I think this location is the easiest and has an entrance to a bike path right across the street.
It's one of the most iconic spots in county Kerry: the Gap of Dunloe. And yes, it is a public road, so you are allowed to drive it up and down. But, during the tourist season it will be packed with walkers, cyclist, horses and carriages making their way up the gap.
This is an Arnold Palmer Jewel.
