Pigeon Hole Cave

Highlight • Cave

The cave is in the forest on a small hill. There are stairs down that we couldn't climb as a rappelling course was going on. It's definitely worth looking down.

The Pigeon Hole is a limestone cave located between Lough Corrib and Lough Mask just outside of the village of Cong. A steep descent of steps with a welcome handrail will bring you down to the main cavern, a fairly substantial space over 12-feet wide with a subterranean stream running through it. The cave gets its name from the fact that it’s a common place for pigeons to nest.

Glengowla mine opened in 1851 and was active until 1865 for the excavation of mostly silver and lead. It is now open to visitors and provides an interesting insight into the hardships miners faced in the 19th century. It is well worth a visit on your tour, but do take an extra layer to the mine as it can get chilly down there. There are sheepdog demonstrations on site too. For more information see the websitehttps://www.glengowlamines.ie/

Kelly's Cave lies in woodland 500 m (1,600 ft) northeast of Cong. The cave is about 16 m long and consists of two rectangular chambers and a hole in the roof which acts as a skylight. Four steps lead down to an underground stream, and benches have been carved into the walls. The entrance is blocked with an iron gate. The path to the grave (about 160 meters) is very impressive too - large stones (coverd with moss) stand and lie along the path. https://en.wikipedia.org/wiki/Kelly%27s_Cave

In this rock face, 17 caves open into the interior of the mountain. Many legends are told about this place, among other things a king is said to have been born here and raised by a she-wolf. The bones of all kinds of animals have been found under the cover of the mountain, including cave bears, lemmings and reindeer. Prehistoric people also sought protection here.

Beautiful long sandy beaches that invite you to take long walks. From the beach you have great views of the cliffs that surround the beach on both sides. In addition to the fantastically beautiful sand dunes, you will also find a small cave under the cliffs that you can explore. The sheltered bay of Carrowteige is great for swimming.
