Burren National Park covers about 1,500 hectares in the south-east of the Burren, and it is the smallest of Ireland's national parks. It opened in 1991 on land bought by the state for conservation, and takes in limestone hills, bog, heath, grassland and woodland. The centrepiece is Mullaghmore, a 180-metre limestone hill that's among the most striking shapes in the Burren.
There is no visitor centre in the park itself: a plan to build one was dropped after a long and bitter controversy. The information point is in Corofin. The waymarked Mullaghmore Loop is the walk to do, over rough limestone pavement and up the hill. Wear proper boots: the grikes are deep and the rock is slippery when wet.
