6 Best Sights in County Clare, Galway, and the Aran Islands, Ireland

After a number of tit-for-tat burning of castles by the Normans and local chieftains on or nearby the current castle, the McNamara clan built the existing 15th-century Bunratty Castle. It was once the stronghold of the O'Brien family who became the Earls of Thomond before they left Ireland in the 17th century for a change of identity and cozier lifestyle in England, but the castle is the park's highlight. It's now fully restored to its former glory, including everything from its carefully chosen period furniture to its "murder holes" that allowed defenders to pour boiling oil on attackers below. The views across the Shannon River from over the battlements are spectacular. Bunratty Folk Park has a carefully planned reconstruction of a typical 19th-century village, which comes complete with school, haberdashery, and, of course, a fully stocked Mac's Pub. Other highlights scattered about the park include the Shannon Farmhouse, the park's first exhibit, which was transported stone by stone from a site earmarked for Shannon Airport's main runway, and the 1898 Hazelbrook House, which was the home of Ireland's most famous ice-cream producers. Pa's Pet Farm and the Fairy Trail keep younger visitors intrigued. The castle runs epic annual events at Halloween and Christmastime. A café and high-end gift store at the entrance to the park has good-quality lunch bites.

Visit Bunratty Castle first as it is the earliest attraction to close (at 4 pm, to facilitate the evening banquets).

Like a chess piece flung onto a windswept rock a short stroll from the village of Kinvara, Dunguaire Castle has braced the Atlantic for 400 years, replacing the king of Connaught's 6th-century palace upon its construction. Built in 1520 by the O'Hynes clan, the tiny storybook castle takes its name from the fabled king of Connaught, Guaire. In 1924 it was purchased by Oliver St. John Gogarty, the noted surgeon, man of letters, and model for Buck Mulligan, a character in James Joyce's Ulysses. Many of the leading figures of the 19th-century Celtic revival in Irish literature came to visit his west coast outpost. Today Dunguaire is used for a medieval banquet that honors local writers and others with ties to the West, including Lady Gregory, W. B. Yeats, Seán O'Casey, and Pádraic Ó Conaire.

Book in advance for the medieval banquet.

Lynch's Castle, once the stronghold of Galway's ruling family, dates back to 1600. These days it's occupied by a branch of a local bank, making its stone fireplace accessible to the public. Check out the gargoyles peering from its facade before heading around the corner to find Lynch's window. According to legend, magistrate and mayor James Lynch FitzStephen hanged his son from its sturdy Gothic frame as punishment for the murder of a Spanish sailor.

This ruined 15th-century tower house (also referred to as An Tur Faire or "the tower ruin") dominates the island from the top of a steep rocky hill; a martello tower keeps it company.

It's a strange experience to walk across the little wooden bridge above reeds rippling in the lake into Ireland's Celtic past as an aircraft passes overhead on its way into Shannon Airport—1,500 years of history compressed into an instant. But if you love all things Celtic, you'll have to visit the Craggaunowen Project. The romantic centerpiece is Craggaunowen Castle, a 16th-century tower house restored with furnishings from the period. It was a retreat for "Honest" Tom Steele, a local squire who famously canvassed Pope Pius VII to change his religion before he had a change of heart and became a key figure in Catholic emancipation. Look for Steele’s initials carved into a stone quoin outside the castle. Huddling beneath its battlements are two replicas of early Celtic-style dwellings. On an island in the lake, reached by a narrow footbridge, is a clay-and-wattle crannóg, a fortified lake dwelling; it resembles what might have been built in the 6th or 7th century, when Celtic influence still predominated in Ireland. The reconstruction of a small ring fort shows how an ordinary soldier would have lived in the 5th or 6th century, at the time Christianity was being established here. Characters from the past explain their Iron Age (500 BC–AD 450) lifestyle, show you around their small holding stocked with animals, and demonstrate crafts skills from bygone ages. Be sure to check out the Brendan boat, a hide vessel used by explorer Tim Severn to test, and prove, the legend that Irish St. Brendan discovered America in a curragh boat almost a millennium before Christopher Columbus.

The park is hilly in parts, particularly near the wild boar compound. Bring comfortable walking shoes.

W. B. Yeats wrote some of his finest poetry, including "The Tower" and "The Winding Stair" in Thoor Ballylee, a small castle just an eight-minute drive from Gort. You can take the winding staircase that led the famous poet up to his writer's garret. A tablet with the words "I, the poet William Yeats, With old mill boards and sea-green slates, And smithy work from the Gort forge, Restored this tower for my wife George. And may these characters remain, When all is ruin once again" is mounted outside as a testament to the time he spent in his summer retreat. Fans of Hollywood's golden age will remember Maureen O'Hara's character, Mary Kate Danagher from John Ford's movie The Quiet Man (1952), rambling by the river at the foot of the tower house.

The tower house is susceptible to flooding so call ahead.
