Where is it?
Blood Falls is a striking natural phenomenon located in Taylor Valley, one of the McMurdo Dry Valleys in Antarctica. The falls flow from the Taylor Glacier into Lake Bonney, an ice-covered lake in this arid, polar desert region. Despite being one of the coldest and driest places on Earth, the stark red hue of Blood Falls makes it a fascinating and otherworldly sight.
What is it?
Blood Falls is a bright red, iron-rich brine that seeps out of the Taylor Glacier. Its eerie color is caused by iron oxidation—when the iron-rich water from a subglacial lake below the glacier comes into contact with oxygen at the surface, it rusts, producing the blood-like hue. The water emerging from Blood Falls has been trapped beneath the glacier for millions of years, isolated from sunlight, oxygen, and external life. This makes it a unique environment for studying microbial life and ancient ecosystems. Scientists are particularly interested in its implications for astrobiology, as it offers insights into how life might survive in extreme environments on other planets.
Best Time to Visit
Visiting Antarctica is only feasible during its summer months, from November to February, when the continent experiences 24-hour daylight and conditions are suitable for research and exploration.
While there are no direct tourist visits to Blood Falls, expeditions to the McMurdo Dry Valleys are rare and usually restricted to researchers. However, some cruises or guided Antarctic tours may offer distant views or discussions about this phenomenon.
Why Should You Visit?
Unparalleled Natural Wonder: Blood Falls is one of the most visually arresting and scientifically fascinating landmarks in Antarctica.
Scientific Significance: Learn about the ancient subglacial ecosystems, extreme microbial life, and geochemistry that contribute to the phenomenon.
Remote Beauty: The McMurdo Dry Valleys are among the most Mars-like environments on Earth, offering a surreal landscape unlike any other.
Astrobiological Implications: Blood Falls provides a glimpse into how life might persist in extreme, isolated environments, such as beneath the icy crusts of moons like Europa or Enceladus.
Tips for the Trip
Antarctic Tours: Book a specialized Antarctic cruise or expedition that explores the McMurdo Sound region. While Blood Falls itself may not be accessible, such trips often include scientific lectures and close encounters with the surrounding unique landscapes.
Gear: Antarctica requires extreme cold-weather gear, including insulated jackets, gloves, waterproof boots, and UV-protective eyewear.
Permits: Access to sensitive areas like the Dry Valleys is heavily regulated to protect the fragile environment, and visits are usually limited to researchers.
Mount Erebus

Where is it?
Mount Erebus is located on Ross Island in Antarctica, within the Ross Dependency region. It is the southernmost active volcano on Earth and rises to an elevation of 3,794 meters (12,448 feet). Ross Island itself is situated in the Ross Sea, near the continent’s edge, and is also home to McMurdo Station, one of the largest research bases in Antarctica.
What is it?
Mount Erebus is an active stratovolcano and one of the few volcanoes in the world with a persistent lava lake. This geological feature, a rare phenomenon, makes Erebus particularly unique and scientifically significant. The volcano was discovered in 1841 by Sir James Clark Ross and named after one of his expedition ships, HMS Erebus. The volcano’s activity is characterized by continuous eruptions and the formation of striking ice fumaroles—towering structures of ice that form around gas vents. These features, along with its rugged landscape and extreme conditions, make Mount Erebus a valuable site for studying volcanology and microbial life in extreme environments.
Best Time to Visit
Access to Antarctica, including Mount Erebus, is only possible during the Antarctic summer (November to February). However, visits to Mount Erebus itself are typically restricted to researchers due to its remote and hazardous environment. Some Antarctic cruises may provide distant views of Ross Island and the volcano.
Why Should You Visit?
Unique Volcanic Activity: Witness one of the only persistent lava lakes on Earth.
Scientific Importance: Learn about its role in studying extreme environments and its implications for understanding volcanic systems.
Remote Beauty: Explore Ross Island’s stark and icy landscapes, offering a unique glimpse into the planet's most inhospitable regions.
Tips for the Trip
Antarctic Cruises: If visiting as a tourist, select an Antarctic cruise that includes the Ross Sea region for a chance to view Mount Erebus.
Extreme Conditions: Be prepared for subzero temperatures and unpredictable weather; ensure your gear meets Antarctic standards.
Restricted Access: Direct access to Mount Erebus is limited to researchers, so consider tours or lectures provided by scientists aboard cruises to learn more.
