Chicxulub Crater
Where is it?
The Chicxulub Crater is located near the town of Chicxulub, on the Yucatán Peninsula in Mexico. It lies about 60 kilometers (37 miles) north of the city of Mérida, in the state of Yucatán. The crater is buried beneath the surface and is not immediately visible, but the surrounding region is home to unique geological features related to the impact event.
What is it?
The Chicxulub Crater is the result of an asteroid impact that occurred approximately 66 million years ago, at the end of the Cretaceous Period. The impact is famously associated with the mass extinction event that wiped out approximately 75% of all species on Earth, including the non-avian dinosaurs. The asteroid that created the Chicxulub Crater is estimated to have been about 10 kilometers (6 miles) in diameter. When it struck Earth, the explosion released an amount of energy equivalent to billions of atomic bombs. This catastrophic event caused massive wildfires, tsunamis, and an "impact winter," where dust and particles blocked sunlight, leading to global cooling and disruptions to ecosystems. Today, the Chicxulub Crater is considered one of the most significant impact sites in Earth's history, playing a crucial role in the study of mass extinctions and planetary geology. The crater itself is buried beneath sediment, but its impact has left profound geological evidence in the surrounding region.
Best Time to Visit
The best time to visit the Chicxulub Crater area is during the dry season, from November to April, when the weather is more comfortable and accessible for travel. The region can get quite hot during the summer months, with high humidity and occasional rainfall.
Why Should You Visit?
Historical and Scientific Significance: The Chicxulub Crater is directly linked to one of the most important events in Earth's history—the extinction of the dinosaurs. Visiting the site allows you to connect with this pivotal moment in time.
Unique Geological Site: Although the crater is buried, visitors can explore the surrounding region and learn about the geological evidence left behind by the impact.
Educational Opportunity: The Chicxulub Crater is the subject of scientific research, and there are museums and visitor centers in the area that provide information about the impact event and its global consequences.
Cultural Experience: The Yucatán Peninsula offers a rich cultural experience, with ancient Mayan ruins, vibrant cities, and a unique cuisine, making it an interesting destination beyond the crater itself.
Tips for the Trip
Guided Tours: For a deeper understanding of the Chicxulub Crater's significance, consider joining a guided tour, where experts can explain the scientific details and history of the site.
Nearby Attractions: While visiting the crater region, take time to explore nearby attractions, such as the Mayan ruins of Chichen Itza (a UNESCO World Heritage Site), the Cenotes, and the beautiful coastal areas of the Yucatán Peninsula.
Travel Logistics: The nearest major city to the crater is Mérida, which can be reached by flight from Mexico City or other major airports. From there, you can hire a local guide or join an organized tour to the Chicxulub area.
Clothing and Gear: Dress appropriately for the tropical climate. Lightweight clothing, sunscreen, and a hat are essential for staying comfortable during the visit.
Naica Giant Crystals

Where is it?
The Naica Mine is located in the Chihuahua state of northern Mexico, near the town of Naica. The mine is situated in the Sierra de Naica mountain range, approximately 300 meters (980 feet) below the surface, making it one of the most fascinating geological sites in the world. The mine itself is located in a region known for its rich mineral deposits, including silver, lead, and zinc.
What is it?
The Naica Giant Crystals are some of the largest naturally occurring crystals ever discovered on Earth. These massive selenite crystals (a variety of gypsum) are found in the Cave of the Crystals, located within the Naica Mine. The largest of these crystals is over 11 meters (36 feet) long and weighs approximately 55 tons. These giant crystals were formed over thousands of years in the extremely hot and mineral-rich environment of the cave, which is filled with hydrothermal fluids. The crystals formed under unique conditions—particularly the combination of high temperatures (about 50°C or 122°F) and high humidity, allowing the crystals to grow to such extraordinary sizes. The crystals are transparent and extremely delicate, adding to the mystique and allure of the site. Access to the cave is extremely restricted due to its dangerous conditions and the delicate nature of the crystals. The area was closed to the public after the discovery of the crystals to preserve the site and protect both the crystals and the miners. However, it remains an iconic location for geologists and mineral enthusiasts.
Best Time to Visit
Due to the extreme temperatures and the fact that the cave is not open to tourists, direct visits to the Naica Cave of the Crystals are not possible. The mine and cave are generally off-limits to the public. However, there are efforts to develop educational programs and tours of the surrounding areas of Naica that can provide insight into the geological and scientific significance of the crystals.
The surrounding region, including the town of Naica, can be visited year-round, but the best time for travel is during the cooler months, from November to February, to avoid the intense heat typical in the summer.
Why Should You Visit?
Geological Wonder: The Naica Giant Crystals are one of the most remarkable natural phenomena on Earth, offering a unique insight into crystal formation and the conditions required for the growth of such massive structures.
Scientific Importance: The discovery of the crystals has helped researchers understand more about the conditions needed for crystal growth and the types of minerals present deep underground.
Cultural Experience: While direct access to the cave is restricted, the region around Naica offers opportunities to explore Mexican culture, the mining history, and nearby natural sites, such as the Cueva de las Vírgenes and Cueva de los Murciélagos.
Photography and Visual Appeal: For those interested in photography, the giant crystals, even if only seen through images and documentaries, offer stunning visuals of one of the Earth’s hidden wonders.
Tips for the Trip
Nearby Attractions: While you cannot visit the Cave of the Crystals directly, consider exploring other attractions in Chihuahua, such as the Copper Canyon or the Mennonite communities, known for their unique culture.
Scientific Tours: Check for special tours or educational programs in the area that might provide a more in-depth understanding of the crystals and the geological significance of the Naica Mine.
Dress Appropriately: If you plan to visit the surrounding area, bring light, breathable clothing and sun protection, as the region can experience extreme heat, especially during the summer months.
