One of the most incredible landscapes in all of Ireland. A series of lakes connected to each other, immersed in green mountains and fields of free-grazing sheep. Very easy trekking on a paved road, occasionally used by cars and horse-drawn carriages. In a couple of places you can reach the water of the lake and sit on the shore.

A beautiful salt lake, separated from the sea by a narrow passage. In the center of the lake a small island with the ruins, unfortunately not visible from the coast, of Clohane Castle. From here the path to Knockomagh starts, very steep but with a 360° view of the entire valley.

"Where the mountains rise to the oft-changing skies, And the castle stands stately and gray; Where the still lake still lies, beneath that wild, rugged hill, In the vale of lovely Glenveagh..." By: Herbert W.K. Sterritt

The park is rectangular and surrounded by main roads on all sides. During the summer months, free concerts and theatre performances are regularly held there on weekends. Changes in traffic routing led to a drastic reduction in road traffic in 2004. A terminus of Line B of the new Dublin tram (Luas) is located directly on the western side of the park. Plans to excavate a large part of the park as part of the expansion of the Dublin Metro North Line have raised serious concerns that the character of the park could be irreparably changed by the associated interventions.

We really enjoyed visiting Ross Castle in Killarney. This castle is particularly impressive from the outside and the surroundings with the beautiful lake are just totally romantic. I personally didn't find the interior that spectacular, but once you've had a look around the castle you'll be rewarded with a fantastic view at the top!
