The Burrens had the best example of Ireland's Rendzina soils. The exposed limestone stretched on for what seemed like miles. There was ivy, orchids, and other natural flora all over the rocks. The plants grow in pits from erosion from wind or water.
Even though it was from 1962, it was still very interesting to look at.
Though the soil was not red like Tara from Gone with the Wind, the beauty of the landscape is second to none. Even if you aren't interested in soil, the topography and landscapes of the island are so worth the trip.
