It is made of about 40,000 basalt columns. Basalt is a dark volcanic rock. These columns look like big stepping stones. Most of them have six sides. Some have four, five, seven, or eight sides.

These stones formed a long time ago. About 50 to 60 million years ago, there was much volcanic activity. Hot, liquid lava flowed through the ground. As the lava cooled, it began to shrink. This is called contraction. The cooling lava cracked just like drying mud. These cracks went deep into the ground. This created the tall, pillar-like shapes we see today.

Some people tell a fun story about the stones. They say a giant named Fionn mac Cumhaill built them. Legend says he built the path to meet a rival.

Many people visit the site to see it. Nearly one million people visited in 2019. It is a very famous natural wonder.
