22-Day Everest Base Camp Trek and Island Peak Climb in Nepal

Climbing Island Peak (6,160 meters / 20,210 feet) is an incredible adventure, but it is not just a walk in the park. It is a real mountain climb that requires serious preparation.

• It is a real technical climb, not a trek. Many people think Island Peak is just a hard hike because it is called a "trekking peak." It is not a trek.

• The hardest part is a steep, 100-meter (328 feet) wall of ice and snow. You will climb up a 40 to 50-degree slope.

• Safety lines: you must know how to use a Jumar (an ascender tool to pull yourself up a rope) and a figure-eight descender to rappel (slide down the rope) safely.

• Crampons and axes: you will walk across a glacier wearing heavy plastic mountaineering boots, crampons (spikes on your boots), and holding an ice axe.

• High altitude: Island Peak sits over 6,000 meters high.

• The air has less than half the oxygen compared to sea level.

• Acclimatization is key: your 22-day schedule must include slow walking days to let your body get used to the thin air. Skipping days to go faster will make you sick.

• Altitude sickness (AMS): you need to know the signs of altitude sickness, like bad headaches, dizziness, or vomiting.

• If these get bad, you must descend immediately.

• Ultimate physical fitness is required. You will be hiking for weeks before you even reach the peak.

• The actual summit day is exhausting. Summit day: you will wake up around 12:00 AM or 1:00 AM and climb for 10 to 14 hours straight in freezing cold temperatures.

• Training: months before your trip, you should practice walking uphill with a heavy backpack, running, and doing leg exercises like squats.

• Essential gear: rent or buy? You need special gear that you do not use on normal hikes. You can buy this gear at home, or rent it very cheaply in Kathmandu or the village of Chhukung right before the climb.

• The Big Five: you will need mountaineering boots, a climbing harness, an ice axe, crampons, and a helmet.

• Layers: temperatures near the top can drop to -15°C (5°F) or colder.

• High-quality thermal underwear, a thick down jacket, and heavy gloves are mandatory.

• Autumn vs. spring weather: while both are peak seasons, they offer different conditions.

• Spring (March-May): the weather is warmer, but there is more snow on the mountain. This can make the climb softer but sometimes more tiring.

• Autumn (Sept-Nov): the air is incredibly clear, but it is much colder and the mountain can have more hard, exposed ice.

• Insurance must cover helicopter evacuation.

• Normal travel insurance will not protect you on Island Peak.

• The 6,000-meter rule: your insurance policy must specifically say it covers medical care and helicopter rescue up to 6,000 meters.

• If you get severely sick or hurt, a helicopter is the only way out of the mountains, and it costs thousands of dollars if you do not have insurance.
