Follow the water - Along Ireland's rivers and lakes
The most beautiful place in the world. I arrived here after two weeks of cycling along the Wild Atlantic Way, and I didn't know I'd find a place of this majestic beauty. It was so disarming that I decided, in May 2022, to find a hostel and return the following day to complete the trail along the cliffs and reach the One Man Pass. It remains my most beautiful memory, and every time I see this shot, I think back to that day. The most beautiful place in the world

"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

A beautiful view of the Irish Fujijama. Near the hotel on the road there are a few archaic round stone posts which, together with the water, provide a beautiful foreground.

Had a great meal at “The Rusty Mackerel” then cycled up to the cliffs at Sliabh Liag for an amazing sunset over the sea. Beautiful!

Great castle that was once seen in a James Bond film. It is located in the middle of a large national park that is worth hiking.

Worth the walk out to the lighthouse. There are steps from the lighthouse gate down to a small cove. Probably OK to swim here in the summer. Definitely not a winter swim!
