The famous lakes of Killarney National Park
Killarney became Ireland’s first national park: it opened in 1932, when the Muckross estate was transferred to the state (park history). Today about 103 sq km of forest, mountains, and water are protected (as of 09/2026, Killarney National Park).
The main reason people come here is the three lakes. Lough Leane, Muckross Lake (also called the Middle Lake), and the Upper Lake are connected by channels. Along their shores grow the country’s largest oak and yew woodlands. The park is home to deer, badgers, pine martens, and squirrels. You may spot them in the morning, before the crowds arrive.
Above Lough Leane rise Torc, Mangerton, and Carrauntoohil, the country’s highest peak. Nearby stand Muckross House, Muckross Abbey, and Innisfallen Island with its old monastery. Ross Castle fits into this landscape as its focal point on the water.
History of Ross Castle
Ross Castle was built in the late 15th century. It was raised by a chieftain of the O’Donoghue clan, head of the Irish Ross family (castle description). The fortress didn’t serve the family for long: within a century it was handed over to the English settler Valentine Browne.

The defense was led by Lord Muskerry. The defenders believed in a prophecy: the fortress would fall only when a ship sailed across the lake (as of 09/2026, siege chronicle).
Knowing of the prophecy, Cromwell's commander General Ludlow launched a large longboat with artillery onto the water. When the defenders saw the vessel, they surrendered, and the prediction came true. This is how the event is described in the castle's official history (source).
After the surrender, the fortress was turned into barracks. Weapons were stored here, food was prepared, and soldiers were quartered. For the Irish, the castle became a symbol of the struggle for independence, which is why so many legends surround it.
The castle outside and inside
Ross is a typical 15th-century tower house. The walls are built of local gray stone, and round towers with arrow loops rise at the corners. Inside, oak furniture from the 16th and 17th centuries and armory rooms have been preserved. Such towers were built by clan chieftains for living and protecting their kin, and this is best seen here.

Above them lived the guards: narrow rooms, earthen and straw floors, almost no furniture. Further up were the kitchen and dining halls for the servants. You will notice how modestly those who defended the tower lived.
On the fourth floor were the owners' bedrooms, and the fifth was occupied by the great hall. Its stone floor protected people from fire. The hall also had an escape exit for fleeing during a siege. All five floors and the towers are connected by a single spiral staircase. As you climb it, you will feel the draft between the open doors.
Legends of Ross Castle
A legend about O'Donoghue is connected with the castle. The chieftain vanished from the window of the upper tower together with his furniture and favorite horse. He flew on horseback over the water and disappeared into the depths of Lough Leane.

Whoever sees the horseman will have good luck all year. Locals call him a guardian spirit and believe that he protects his people.
The grounds around the castle are also lovely. On one side they are rugged and rocky, on the other they delight with soft meadows and groves. Bring a warm jacket: it is windy near the water even in summer. A walk along the shore will add half an hour to your trip, but it is what gives you a sense of the park's scale.
