These beautiful travertine terraces in northern Iran are an incredible natural phenomenon that has evolved over thousands of years. Travertine is a type of limestone that is formed from calcium deposits in flowing water, and in this case, it is two hot springs with different mineral properties. The abnormal reddish color of the roof is caused by the high content of iron oxide in a fountain.

In recent years, efforts have been made to preserve the site due to the increase in tourism activity. These locations are one of the strangest places on Earth, providing visitors with a glimpse of one of the most bizarre attractions on the planet.
Sixty million years ago, a huge volcanic eruption released a mass of molten basalt. It hardens and compresses as it cools, creating cracks that can be seen today.

This World Heritage Site contains an estimated 37,000 polygonal columns, geometrically so perfect that local legend says they were created by a giant. It is a strong contender for one of the strangest places in the world.
also known as the Cotton Palace, is a stunning UNESCO World Heritage Site in southwestern Turkey. When you visit, you can also explore the ancient ruins of Hierapolis, a once-great city built around.

Water flows from the natural fountain through the white travertine roof, creating beautiful thermal pools suitable for a quick dip. We recommend joining a small group tour with a guide. In 2023, new rules were introduced to limit the number of visitors to protect the site, so booking in advance is highly recommended.
