Knockboy, or An Cnoc Buí, meaning 'yellow mountain', is the highest mountain in the Shehy Mountains. It has a trig-pointed summit and is easily accessible from Priest’s Leap. There are great views to be had from here all round, but the views towards Bantry Bay are a bit special.

Standing proud on Dursey Island's highest point, at 827 feet (252 m), this signal tower is a fine sight. It was built in the early 19th century as part of a system to enable long-distance communication at a time when Britain feared French invasion. The views from up here are superb, both out to sea and back towards the Beara Peninsula.

While only of moderate height, its enviable position means that the views from the top of Garnish Point are wonderful. To the west is the hilly Dursey Island and the Atlantic horizon, while in the other direction are Ballydonegan Bay and the Slieve Miskish Mountains.

The watchtower on Dursey Island stands proud and deserted on a hilltop, as if a silent witness to times gone by. The path to it is characterized by vast, open grasslands that wind slowly upwards until the tower finally appears before you – an impressive stone structure that has survived the stormy years. As you walk through the mist that often drifts over the island, the tower seems almost mystical, as if it existed in another time. The crumbling walls beside it tell stories of stormy nights and lonely sentinels that once watched the seas. Once at the summit, a magnificent panoramic view of Dursey Island's rugged coastline awaits you – weather permitting. It's worth taking in the peace and solitude up here. The wind whistles around the corners of the tower, and you can imagine what it must have been like to once stand watch in this remote place. The few remaining fortifications give you an idea of the tower's importance in its time. The hike isn't particularly long, but the constant ups and downs require a certain level of fitness. Sturdy footwear is a must, especially in wet weather when the path can be slippery.
