The harbour still offers shelter to a few fishing boats. The Gaelic name means "oak harbour", due to the woods that once covered the area. There are a few cosy and lovely restaurants and pubs that make this charming village a pleasant place for a lunch or an afternoon tea.

A quiet viewpoint, just before B&B Bay View, above Glandore Harbour, with a wide panorama over the sheltered bay and the wooded slopes around the village. In clear weather, you can see the rocky coastline towards Toe Head. A short, quiet stop with beautiful light in the morning and late afternoon.

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.

Nice, but rather unspectacular lake near the beach. We saw almost no waterfowl. But there are some benches and really good hiking trails.

Barley Lake is a real insider tip in the Caha Mountains, nestled in a rugged, boggy landscape. The hike here takes you through a piece of almost untouched nature that has existed since the last Ice Age. The lake, surrounded by steep hills, appears tranquil and mysterious—as if time has stood still. If you set out, you should pack sturdy shoes, as the path is not always easy to find, and in wet weather it can get muddy. What I particularly liked was the isolation of the place. Up here, you hardly meet a soul, and you can concentrate fully on the landscape and the clear, dark lake. If you have a little sense of direction, you can even walk around the lake. You'll be rewarded with new views time and again—over the lake itself and all the way to Kerry. After rain, the ground here is often boggy. Pack some dry socks just in case you sink a little deeper. However, the view and the tranquility that Barley Lake exudes more than make up for this small challenge. The lake reminds you that nature has been carving its own path here for thousands of years. For me, it was a grounding moment—far from crowds and everyday life. It's a place where you should take the time to pause and simply feel the power of nature.

Lough Hyne is truly something special. On my way to the lake I passed through the dense forest of the Knockomagh Woods Trail, where the green of the trees and the chirping of birds cover the hikers like a thick blanket. A quiet, almost mystical place. When you leave the path and suddenly see the clear waters of Lough Hyne in front of you, the landscape opens up in a completely new way. The lake, which is considered a safe place to swim even in rough conditions due to its salt water supply, attracts not only hikers but also swimmers who bathe in the protected waters here all year round.
