At a glance
Trip overview
We organise expeditions to Denali, the highest peak in North America at 6,194 m (20,310 ft), situated within Denali National Park in Alaska. This mountain is one of the Seven Summits, known as much for its extreme cold and heavy load-carrying requirements as for its height. Temperatures can plummet to minus 60 degrees Celsius with wind chill, requiring absolute self-sufficiency and rigorous preparation.
This 20-day expedition is aimed at mountaineers who have prior high-altitude experience and have mastered fundamental glacier travel and rope-handling skills. We operate with a strong emphasis on teamwork, where every member participates in pulling sleds, carrying communal gear, and setting up camps across the vast snowfields and ridges of the Kahiltna Glacier.
Our lead guides manage logistics carefully, from the initial National Park Service briefing in Talkeetna to the bush plane flight onto the glacier. We build active rest days and caching phases into our schedule to ensure proper acclimatisation as we ascend through the successive camps towards the summit ridge.
Why this trek
Trip highlights
Kahiltna Glacier Flight
We take a scenic ski-plane flight from Talkeetna straight onto the southeast fork of the Kahiltna Glacier at 2,195 m (7,200 ft).
North America Summit
We aim to stand on the highest point in North America at 6,194 m (20,310 ft) after navigating the upper mountain ridges.

Before you go
Good to know
Physical Preparation & Fitness
Denali demands an exceptional level of cardiovascular fitness and strength. Participants must train extensively with weighted packs and sled dragging over long distances prior to arrival.
Extreme Weather Conditions
Temperatures on the mountain can drop to minus 60 degrees Celsius with severe wind chill. Proper layering, high-altitude mountaineering boots, and cold-weather management are mandatory.
Team Self-Sufficiency
Unlike guided treks where porters carry loads, our Denali expeditions require every member to haul their own sled and share in camp chores such as melting snow for water and pitching tents.
Weather Contingency
Mountain weather in Alaska is notoriously volatile and can delay flights or summit pushes by several days. We build extra days into our schedule to accommodate these inevitable halts.

Frequently asked questions
What prior experience do I need for Denali?
You must have previous high-altitude mountaineering experience, proficiency in self-arrest with an ice axe, and experience travelling on roped glacier teams.
How heavy are the loads we carry?
Initially, your sled may weigh around 20 to 30 kg, and your backpack will hold another 10 to 15 kg. As we ascend and abandon sleds, backpack weights increase.
Is reaching the summit guaranteed?
No summit is guaranteed in mountaineering. Weather, extreme cold, and individual acclimatisation dictate our progress and safety decisions.
Who provides personal equipment like crampons and harnesses?
You are responsible for bringing your own personal technical gear and extreme cold-weather clothing, though we provide all group gear like stoves and tents.
What happens if weather delays our bush plane?
Weather delays on the Kahiltna Glacier are common. We maintain contingency days in our schedule, but you should allow extra buffer days at the end of your trip.
Do I need specific rescue insurance?
Yes, comprehensive travel insurance that explicitly covers high-altitude mountaineering and helicopter or mountain rescue is mandatory.
