If you look at a map of Uganda and the Democratic Republic of the Congo, you’ll see a jagged green line. That's the Rwenzori Mountains, more famously known as the Mountains of the Moon. Ptolemy, the ancient Greco-Egyptian geographer, first mentioned them nearly 2,000 years ago, claiming they were the source of the Nile. People thought he was crazy. Snow on the equator? In Africa? It sounded like a myth. Honestly, for centuries, Europeans treated it as such, right up until Henry Morton Stanley "discovered" them in the late 1880s. But the locals, the Bakonjo and Baamba people, had been living in their shadows for generations, calling them Rwenzururu, which basically translates to "snow maker."
They aren't just hills. They are a massive, high-altitude ecosystem that defies everything you think you know about tropical geography. We’re talking about peaks reaching over 5,100 meters, shrouded in near-constant mist and home to plants that look like they crawled out of a prehistoric fever dream.
What Most People Get Wrong About the Mountains of the Moon
Most travelers assume the highest mountains in Africa are Kilimanjaro or Mount Kenya. While those are taller, they’re volcanic. The Mountains of the Moon are different. They are a "block mountain" range, thrust upward by the same tectonic forces that ripped open the Great Rift Valley. This makes the terrain incredibly rugged. It's not a gentle slope. It’s a vertical labyrinth of bogs, bamboo forests, and granite walls.
A common misconception is that because they are in the tropics, it's a warm hike. It’s not. It’s wet. Perpetually, bone-chillingly wet. The Ruwenzori Range receives some of the highest rainfall in the world. You aren't just hiking; you’re wading through "Vertical Bogs." If you aren't wearing gumboots (wellies), you’re doing it wrong. I've seen experienced mountaineers crack under the pressure of the mud before they even reach the heather zone.

The Nile Connection: Is the Myth Real?
Ptolemy wasn't entirely wrong. While the Victorian explorers spent years arguing over whether Lake Victoria or Lake Albert was the "true" source of the Nile, the Mountains of the Moon provide a massive amount of the water that feeds the White Nile. The melting glaciers and the constant rainfall flow into the Semliki River, which feeds Lake Edward and Lake Albert. Without these mountains, the Nile's flow would be significantly less stable.
The disappearing glaciers of the Rwenzori
Here is the heartbreaking reality. The ice is vanishing. In 1906, when the Duke of Abruzzi first mapped the range, there were about 6.5 square kilometers of glacial ice. Today? It’s less than one. Some scientists, like those from University College London who have studied the retreat, suggest the glaciers could be gone entirely within the next decade or two.
This isn't just about losing a pretty view. The glaciers act as a water tower. They release water slowly. When they disappear, the surrounding communities will be at the mercy of seasonal rains, which are becoming increasingly unpredictable due to climate change. The "snow maker" is losing its touch.

A Flora and Fauna Trip
Because the Mountains of the Moon are so isolated, evolution went a bit wild here. As you climb, the landscape changes in distinct zones:
- The Montane Forest (1,600m - 2,500m): Massive trees, lianas, and the chance to spot an elusive Rwenzori Turaco or even a forest elephant if you’re lucky.
- The Bamboo Zone (2,500m - 3,000m): A dense thicket where the ground is almost always slippery.
- The Heather Zone (3,000m - 4,000m): This is where it gets weird. Giant heathers, covered in old man’s beard moss, look like something from a fantasy novel.
- The Afro-Alpine Zone (4,000m+): This is the home of the Giant Lobelias and Groundsels. These plants can grow several meters tall and have evolved "antifreeze" fluids to survive the nightly freezes.
Planning a Trek: It's Not for the Faint of Heart
If you’re thinking about visiting, you need to understand that this is one of the toughest treks on the planet. It makes Kilimanjaro look like a walk in the park. The "Central Circuit" takes about seven to eight days. It's a grueling test of endurance.
- Get the right gear. Forget your fancy lightweight hiking boots for the lower sections. You need rubber boots. Seriously.
- Choose your route. The Central Circuit is the classic path, managed by the Rwenzori Mountaineering Services (RMS). There’s also the Kilembe Trail, which is a bit more managed and offers great views.
- Physical Prep. Cardio is key, but so is leg strength. You’ll be pulling yourself up over tree roots and through thick mud for hours.
The Mountains of the Moon offer something that few places on Earth still can: a sense of genuine, untamed mystery. It feels like a place that doesn't want to be explored. The clouds rarely part, but when they do, and you see the sun hitting the glaciers of Margherita Peak, it's a religious experience.

Why You Should Care About These Peaks Now
We are witnessing the end of an era for the African alpine environment. The ecological shift happening in the Rwenzori is a bellwether for the rest of the continent's water security. It's a complex, fragile system.
If you want to see the snows of the equator before they're a memory, you need to go soon. But go with respect. Use local guides. Support the Bakonjo communities. They are the true stewards of these peaks and have the most to lose as the climate shifts.
Essential Steps for Your Expedition
- Book through a registered operator: Uganda Wildlife Authority (UWA) oversees the park. Stick with official partners like RMS or Rwenzori Trekking Services.
- Check your insurance: Ensure it covers "high altitude trekking" up to 6,000 meters and includes emergency helicopter evacuation. Many standard travel policies won't cover the Rwenzori.
- Pack for wet, not just cold: Use waterproof dry bags for everything inside your pack. If your sleeping bag gets wet on day two, you're in for a miserable week.
- Health check: Malaria is a risk at the base of the mountains, but altitude sickness (AMS) is the real danger once you pass 3,500 meters. Pack Diamox and know the symptoms.
The Mountains of the Moon remain one of the world's last great adventures. They aren't just a physical challenge; they are a window into a world that is rapidly changing. Standing on the peaks, looking out over the Congo Basin on one side and the Ugandan savannah on the other, you realize why the ancients thought this was the edge of the world. It basically is.
