Adventurous souls from around the globe come to test their skills and endurance against the river’s might.
The canyon’s 277-mile stretch of the Colorado River features more than 80 major rapids, with difficulty levels ranging from class I (easy) to class V (extremely difficult), and a few considered ‘unrunnable’.
4. The Grand Canyon is Home to a Wide Variety of Wildlife
The diverse habitats of the Grand Canyon support a vast array of wildlife. Over 500 animal species are known to inhabit the park, including mammals, birds, reptiles, and amphibians. From the desert-dwelling bighorn sheep and the elusive mountain lions to the soaring California condors with their impressive wingspans, the canyon is a haven for fauna.
The park’s varying elevations and climates contribute to this biodiversity.
Creatures have adapted to survive in the arid desert climate at the bottom as well as the cooler, forested areas at higher elevations. Further, the Grand Canyon’s protected status offers a sanctuary for many species, including some that are threatened or endangered, highlighting the park’s critical role in conservation efforts.
5. The Grand Canyon Skywalk Offers a Unique View Through a Glass Bridge
For visitors seeking a different perspective of the Grand Canyon, the Grand Canyon Skywalk provides a unique vantage point. This horseshoe-shaped, glass-bottomed bridge extends 70 feet over the edge of the West Rim, allowing visitors to walk out into the air above the canyon floor, which lies 4,000 feet below.
This engineering marvel gives those brave enough to step onto the glass a sensation of floating above the canyon.
It’s a newer attraction, having opened in 2007, but the structure has quickly become one of the canyon’s most popular points of interest.
6. The Grand Canyon Boasts Numerous Ancient Rock Art Sites
The Grand Canyon is not only a wonder of natural history but a rich tapestry of human history as well. Throughout the park, visitors can find numerous petroglyphs and pictographs—rock carvings and paintings created by Indigenous peoples who have lived in the area for thousands of years.
These artworks provide insight into the canyon’s ancient inhabitants and their daily lives, beliefs, and customs.
These archaeological sites are considered sacred and are protected by federal law. They are delicate remnants of the past and are at risk from erosion and vandalism.
7. The Grand Canyon Experiences a Surprising Range of Weather Conditions Due to Its Elevations
The Grand Canyon’s elevation spans from around 2,600 feet to over 8,000 feet above sea level, leading to a dramatic range of weather conditions. The inner canyon often sees extremely high temperatures in the summer, while the rim can experience snowfall and sub-freezing temperatures in the winter.
These varied conditions mean that visitors must be prepared for anything, from intense sun and heat to sudden thunderstorms and cold snaps. The weather can also change rapidly within the park, another testament to the canyon’s vast size and topographical diversity.
This variability in weather greatly affects hiking conditions and visitor experiences, making it vital to check forecasts and plan accordingly.
8. There’s a Town Located at the Bottom of the Grand Canyon
Supai Village, which sits at the base of the Grand Canyon, is considered one of the most remote communities in the continental United States.
Home to the Havasupai Tribe, the village can only be reached by foot, mule, or helicopter, as it is not accessible by road. The village is about eight miles from the nearest trailhead.
The isolation of Supai has helped the Havasupai maintain their traditional way of life. They are known for their deep connection to the land and the natural beauty surrounding them, including the turquoise waterfalls that have become popular with backpackers and adventure seekers.
9. The Grand Canyon Wasn’t Always Known by Its Current Name
Before it became known as the Grand Canyon, this massive chasm had several names. The early Spanish explorers called it “El Gran Cañón,” which translates directly to the Grand Canyon.
However, the Paiute Indians called it “Kaibab,” which means “Mountain Lying Down,” while other Native American tribes had different names for it.
It wasn’t until 1869 that the name “Grand Canyon” was popularized. It was during Major John Wesley Powell’s historic Colorado River expedition when he began referring to it as such in his writings. Over time, this name stuck, and it has since become synonymous with the canyon’s awe-inspiring scale and beauty.
10. There Are Hidden Caves Within the Grand Canyon Many Have Never Seen
The Grand Canyon is home to over 1,000 caves, and only a fraction of these have been fully explored. Of all the caves, only one, the Cave of the Domes on Horseshoe Mesa, is open to the public for tours. The rest remain closed to preserve their delicate ecosystems and archaeological integrity.
These caves are some of the least-accessible areas of the park, with some harboring unique mineral formations, rare animals, and ancient artifacts.
11. The Colorado River That Carved the Grand Canyon is Remarkably Powerful
The Colorado River is the architect of the Grand Canyon, a role it continues to play to this day. The river’s flow through the canyon is immense, with an average discharge of about 12,000 cubic feet per second, a volume that has sculpted the canyon over millennia.
This powerful river is also a critical water source and lifeblood for the southwestern United States, providing water for millions of people and extensive agricultural areas.
Dams like the Hoover Dam have been built across the Colorado River to control flooding, generate electricity, and provide a regular water supply, significantly impacting the river’s natural flow and the canyon’s ecology.
12. Hiking the Grand Canyon Can Take Longer Than You Might Expect
Hiking in the Grand Canyon is a bucket-list activity for many, but the rigorous nature of such treks is often underestimated.
The trek to the canyon floor from the rim and back up is not recommended as a day hike because of the distance, strenuous nature of the trail, and the extreme elevation changes.
Experienced hikers may take two to three days to complete a roundtrip hike to the bottom of the canyon and back.
13. The Grand Canyon is an Important Cultural Heritage Site
In addition to its natural splendor, the Grand Canyon is a place of significant cultural importance. For centuries, it has been home to Indigenous peoples who have left behind a rich legacy of artifacts and dwellings that offer a glimpse into their history and connection to the land.
