The Burren

As you travel north toward Ballyvaughan, the landscape becomes rockier and stranger. Instead of the seemingly ubiquitous Irish green, gray becomes the prevailing color. You're now in the heart of the Burren, a 300-square-km (116-square-mile) expanse that is one of Ireland's strangest landscapes.

The Burren is aptly named: it's an Anglicization of the Irish word bhoireann (a rocky place). Stretching off in all directions, as far as the eye can see, are vast, irregular slabs of fissured limestone, known as karst, with deep cracks between them. From a distance, it looks like a lunar landscape, so dry that nothing could possibly grow on it. But in spring (especially from mid-May to mid-June), the Burren becomes a wild rock garden, as an astonishing variety of wildflowers blooms in the cracks between the rocks, among them at least 23 native species of orchid. The Burren also supports an incredible diversity of wildlife, including frogs, newts, lizards, badgers, stoats, sparrow hawks, kestrels, and dozens of other birds and animals. The wildflowers and other plants are given life from the spectacular caves, streams, and potholes that lie beneath the rough, scarred pavements. With the advent of spring, turloughs (seasonal lakes that disappear in dry weather) appear on the plateau's surface. Botanists are particularly intrigued by the cohabitation of Arctic and Mediterranean plants, many so tiny (and so rare, so please do not pick any) you can't see them from your car window; make a point of exploring some of this rocky terrain on foot. Numerous signposted walks run through both coastal and inland areas.
