Gleninagh Castle is an impressive 16th-century L-shaped tower house that majestically overlooks Galway Bay. A former stronghold of the O'Loughlin clan, it is built from the characteristic limestone of the Burren and remains in remarkably good condition. Beside the castle ruins, you will find a small medieval church, a holy well, and a circular 'fullacht fiadh' (cooking place). The contrast between the robust structure and the bare, grey karst landscape makes this a fascinating historical anchor point along the northern coast of County Clare.

A large, completely hollow limestone castle, even the window frames are made of limestone (built in the 15th century by the O'Brians, rebuilt in the 17th century). A very impressive ruin. On private land.

If you turn towards the coast and follow the small path, you will reach Gleninagh Castle. This L-shaped tower castle from the 16th century sits right on the edge of the Burren and offers a wide view over Ballyvaughan Bay. The castle was once a strategic outpost of the powerful O'Loughlin family, who controlled the region until the late 19th century. An ideal place to get off your bike for a moment, enjoy the impressive location and let the tranquility of this historic tower work its magic on you. The area around the castle, with its mixture of coast and rugged cliffs, offers a varied scenery. Especially on the bike, you get a feeling of traveling back in time, while the barren but fascinating landscape of the Burren offers the perfect backdrop for a relaxing break.

Bunratty Castle is a landmark on the route between Limerick and Ennis. Arriving here by bike is almost like travelling through time - the mighty castle rises imposingly at the side of the road, while the surrounding flowerbeds give the place a lively feel. The name Bun Raite refers to the nearby mouth of the River Ratty, which once gave the place importance. The area around the castle has its own charm. Although Bunratty Castle has seen many upheavals in its history, the architecture is impressively well preserved. It is worth stopping for a moment to look at the details - the massive walls and small windows give you an idea of what life must have been like here centuries ago. The cycle route through the village is also pleasant and quiet, although the traffic around the castle sometimes requires a little attention. A detour to the adjacent Bunratty Folk Park is also an option to get an even deeper sense of Ireland's past. Here you can imagine how people in the past lived their everyday lives – and maybe this is the perfect inspiration for the next section of your bike tour.
