The Burren: when to visit, what to see, and things to know

Famous across the world for its karst landscape, the Burren in County Clare is one of the most spectacular natural beauties in all of Ireland. Here is everything you need to know about the Burren.

Stretching across North Clare, the Burren region has been shaped by numerous geological forces that have taken place over hundreds of millions of years.

The Burren is renowned across the world for its beautiful limestone landscapes, rich archaeological history, and immense wealth of flora.

The rocks that make up the Burren were formed between 359 and 299 million years ago.

Amazingly, the limestone that makes up the Burren was formed in a warm tropical sea near the equator. The limestone is made up of many pieces of broken fossils from corals and other sea creatures.

It is thought that after these rocks were formed, the entire continent collided with what is now Europe. This collision caused the rocks in the Burren to become gently folded or tilted slightly to the south. This collision is responsible for the many cracks that run through the limestone. 

The Burren is scattered with large rocks that are not common to the region, such as granite and red sandstone.

This occurred about two million years ago, thanks to the Ice Age. As the ice started to melt, large rocks and clay were deposited in the Burren region which is still visible to this day.

The Burren region is open 365 days a year. It can be explored no matter the weather once you are dressed appropriately.

Some of the attractions that can be found in the Burren are most popular during the summer months as this is the peak of the tourism season. 

However, if you would like to see some of the beautiful wildflowers that call the Burren home, we suggest visiting here during May.

This is the best time of year as it isn’t incredibly busy, the weather is relatively mild, and the Burren is alive with beautiful colours.
