I summited Kilimanjaro on my first attempt. Barely. At 5,200 meters, I was vomiting into the volcanic scree while my guide gently suggested turning back. At 5,600 meters, I was moving at the pace of a glacier. At 5,895 meters, I was crying and couldn't stop.
I made almost every mistake possible. Here's how to avoid them.
I booked the Marangu Route in 5 days because it was cheaper. The success rate for 5-day Marangu is about 50%. The same route in 6 days jumps to 70%. The Lemosho Route in 8 days has a 90% success rate.
The difference isn't fitness — it's acclimatization. Your body needs time to adjust to decreasing oxygen. At the summit (5,895m), you're breathing half the oxygen available at sea level. An extra day or two costs more but dramatically increases your odds.
The Machame Route ("Whiskey Route") is 6-7 days, 62km, with diverse landscapes: rainforest, heather, moorland, alpine desert, glaciers. Success rate ~85% on 7 days. Camping only.
The Lemosho Route is 7-8 days, starts remote, highest success rate (~90% on 8 days). Fewer crowds.
Marangu is the only route with hut accommodation, which sounds nice. But the acclimatization profile is worse — you ascend too fast. The huts are basic and crowded. I wish I'd chosen Machame.
January-March is colder and quieter. June-October is dry season and busiest. Avoid April-May (heavy rains). Full moon summits are spectacular — check the lunar calendar.
Acetazolamide (Diamox, 250mg twice daily) helps your body acclimatize faster. It's not a magic pill — it doesn't prevent altitude sickness, just reduces the severity. Side effects: tingling fingers and frequent urination. Get a prescription from your doctor before travel.
I didn't take Diamox. I should have.
The Swahili mantra "pole pole" (slowly, slowly) is the most important advice on the mountain. Walk at a pace where you can hold a conversation without getting breathless. If you're gasping, you're too fast. Your guide will set the pace — trust them even when it feels absurdly slow.
Dehydration worsens altitude sickness. Force yourself to drink even when you're not thirsty. Bring water purification tablets or a filter — refilling from streams saves carrying weight.
If you have a headache, stop. Rest. Hydrate. Take paracetamol. If it doesn't improve, descend. Ignoring a persistent headache at altitude can lead to dangerous cerebral or pulmonary edema. This is how people die on Kilimanjaro.
Cotton absorbs moisture and takes hours to dry. At altitude, wet clothing causes hypothermia. Wear merino wool base layers and synthetic mid-layers. A good rain jacket is non-negotiable — the rainforest zone gets heavy rain.
I packed cotton t-shirts. By Day 2, they were damp and stayed damp for the rest of the trek.
You need a bag rated to -15°C minimum. Nights at high camp (4,600m+) drop well below freezing. Rent in Moshi ($5/day) if you don't want to buy one, but inspect the bag before accepting it — quality varies from "warm enough" to "glorified blanket."
New boots on Kilimanjaro = blisters on Day 1 = misery for the remaining 6 days. Wear your trekking boots for at least 20-30 hours before the trek. On different terrain. Up and down hills.
Chemical hand warmers inside your gloves are the difference between functional fingers and painful ones at -20°C during the midnight summit push. Bring 4-6 pairs.
Summit night starts at midnight. You'll walk 6-8 hours in darkness. You need a headlamp with fresh batteries (bring spares — cold drains batteries fast). Your phone flashlight will die, and then your phone will be dead when you want summit photos.
Solo trekking is illegal on Kilimanjaro — you need a licensed guide and registered operator. Budget: $1,800-2,500. Mid-range: $2,500-3,500. Premium: $3,500-5,000+.
The price includes park fees ($70/day), guides, porters, food, camping equipment, and transport. Park fees alone for a 7-day trek are $490. When operators charge $1,800 all-in, the only place to cut is porter wages.
Tipping is expected and significant. Standard: lead guide $20-25/day, assistant guide $15-18/day, cook $10-15/day, porters $8-10/day each. For a 7-day trek with a typical crew, that's $250-400 in USD cash (small bills).
After the trek, many travelers fly to Zanzibar for beach recovery. Ethical operators pay porters 10,000+ TZS/day with a maximum carry weight of 20kg. Cheaper operators underpay and overload. Ask before booking. The Kilimanjaro Porters Assistance Project (kiliporters.org) maintains a list of partner companies.
You start at midnight. It's dark. It's cold — minus 10 to minus 25°C depending on wind. You walk in a line of headlamp beams, switchbacking up loose scree. The pace is painfully slow. Your legs feel like concrete. Your lungs burn. Some people vomit. Some cry.
And then the sky lightens. The glaciers catch the sunrise. The clouds are below you. Uhuru Peak's sign appears.
Fifteen to thirty minutes at the top. Then you descend.
The summit moment at 5,895 meters — sunrise on the Roof of Africa. The gateway city of Nairobi is another option for Kilimanjaro connections — is worth every miserable step of the night before.
Moshi is a charming gateway town at 900m. After 7 days on the mountain, the oxygen feels luxurious. Celebrate with a coffee tour (Chagga people grow arabica on the lower slopes, half-day $30-50 USD, plantation to cup), a beer at Kilimanjaro Breweries, or a visit to Materuni Waterfall (2-hour hike, 20,000 TZS entry).
You earned it. For a day-by-day account of the climb, read our Kilimanjaro trekking journal.
