Expeditions · Company records 2026
By Richard J. · written from ValenciaRecord score 52/100Verified 26 September 2026
Madison Mountaineering scores 52/100 as a company record, fifth of the nine mountaineering companies scored: the Jackson, Wyoming, guiding company founded by Garrett Madison in 2014 prices eleven expeditions in full, from K2 at USD 75,500 to a nineteen-day Everest Super Express at USD 128,950, but shows no financial protection and no independent review. This record covers the company behind the guiding, not the mountain: who owns it, its guides and Sherpa team, what each climb costs, the payment and cancellation terms, support, the safety facts it prints and the gaps. Our Everest and Seven Summits indexes linked below rank the climbs; this page scores the company.

Madison Mountaineering scores 52 out of 100: full marks for pricing transparency, held back to zero on both reviews and financial protection. Its 65 on our Seven Summits operator index is not a contradiction: that index scores what each climb includes and discloses, such as price, guide ratio and oxygen, while this record scores what a buyer can check before paying, such as terms, protection and reviews.

Madison Mountaineering publishes a price, a deposit and a day-by-day itinerary for almost every expedition it sells, and names its guides and its own Sherpa team down to the sirdar. It does not publish a street address, a graduated cancellation scale, a guide ratio for most of its climbs, or a single independent review anyone can check.

The record holds 17 facts about Madison Mountaineering, each with its source and grade. Grade A means the company's own site or terms; grade B means a registry, review platform, awarding body or major press; grade C means a secondary source not confirmed elsewhere. Every line was read on 26 September 2026 unless its source says otherwise.

Madison Mountaineering is owned and led by its founder, Garrett Madison, who has run the company every year since 2014 and states 15 Everest summits and five on K2.
Kurt Hunter is named beside him on the About page as "Technical Advisor / Co-Founder", though the site does not say what he co-founded or how the roles divide. Madison's own pages do not agree on his personal Everest client record: "90+" on the About page against "over 80 climbers" on the Everest expedition page, both read on 26 September 2026. Where Madison sits against the other mountaineering companies is set out on our Seven Summits operator index and Everest expedition operators index.
Madison Mountaineering names more than 20 guides on its About page and leads every Himalayan climb with its own employed Sherpa team, under sirdar Aang Phurba Sherpa since 2015.
Named guides include Estalin Suárez, an IFMGA guide with 17 years guiding after 20 years of climbing, and Scott Webster, who holds the WMCI, the UK's highest climbing-instruction qualification, and is IPGA certified. Seth Timpano is named with 14 years as a professional guide and more than 45 international expeditions but no formal guide certification quoted, on the same About page. What a guide's IFMGA certification actually covers is explained in our guide to what to expect on an expedition.
Madison Mountaineering expeditions read for this record cost from USD 7,950 for 11 days on Elbrus to USD 128,950 for the 19-day Everest Super Express. All prices were read on 26 September 2026 on Madison's own expedition pages; Everest is sold in four tiers from the same page.
| Expedition | Region | Length | From, per person |
|---|---|---|---|
| Everest South Col (standard) | Nepal | 42 days | USD 79,500, 13 April to 25 May 2027 |
| Everest and Lhotse combination | Nepal | 42 days | USD 98,975, 2027 season |
| Everest Express | Nepal | 30 days | USD 85,000, 2027 season |
| Everest Super Express | Nepal | 19 days | USD 128,950, 2027 season |
| K2 | Pakistan | 42 days | USD 75,500, 24 June to 4 August 2027 |
| Lhotse | Nepal | 42 days | USD 49,500, 13 April to 25 May 2027 |
| Vinson | Antarctica | 15 to 16 days | USD 55,950, five departures, 23 November 2026 to 22 January 2027 |
| Denali | United States | 22 days | USD 16,995, 5 to 26 June 2027 |
| Aconcagua | Argentina | 15 days | USD 9,950, three 2027 departures from 5 January |
| Carstensz Pyramid | Indonesia | 11 days | USD 26,500, 2 to 12 March 2027 |
A private ascent of Everest is on enquiry rather than a published tier price. Kilimanjaro, at USD 8,450 for the climb combined with a Serengeti safari, is priced only with 2026 dates on the pages read, with no 2027 date or price found; Elbrus, at USD 7,950, is priced with 2027 dates (15 to 25 July and 6 to 16 August). Every priced expedition excludes international airfare and the medical and evacuation insurance Madison requires; a helicopter evacuation from Everest Base Camp to Kathmandu, where offered, costs about USD 2,000 more. What that required cover should include is in our guide to high-altitude trekking insurance.
Madison Mountaineering takes a deposit of USD 2,000 to USD 25,000 depending on the peak, wants the balance 120 days before departure, and states that nothing paid is refundable however the expedition ends.
| When you cancel | What you pay |
|---|---|
| At any point before or during the expedition | The full deposit and balance already paid; Madison states there are no refunds for weather, route conditions or a summit not reached, though it may waive fees case by case |
No USTOA membership, Washington seller-of-travel number or trust or escrow account statement could be found on Madison's expedition insurance page or elsewhere on its site, and a Washington state registration lookup could not be completed. Clients must buy their own medical and evacuation cover; Madison names Redpoint Resolutions, Global Rescue and AIG Travel Guard as providers to consider, without recommending one over the others. How that compares with other operators is in our Seven Summits operator index.
Madison Mountaineering publishes one phone number with no stated hours and no 24-hour label, and its in-trip updates are public dispatch blog posts rather than a named tracking system.
Compulsory medical and evacuation insurance is the client's own purchase, at a level Madison does not itself state as a minimum for every peak. Choosing that cover is covered in our guide to high-altitude trekking insurance.
Madison Mountaineering prints a guide ratio for two of its nine priced peaks, no oxygen figures for any of them, and an unsupported claim about its own safety record.
| Safety fact | What Madison Mountaineering prints | Source |
|---|---|---|
| Oxygen allocation | No bottle count or flow rate for any peak; K2 says only "plentiful oxygen for all climbers & Sherpas" and Lhotse says oxygen is used above Camp 2, at Camps 3 and 4 and on summit day, again with no figure | K2; Lhotse |
| Guide and Sherpa ratio | Published for two of nine priced peaks: Vinson at a maximum of four climbers to one guide, Denali at one guide to two clients "to begin the program"; not stated for Everest, K2, Lhotse, Aconcagua, Kilimanjaro, Elbrus or Carstensz | Vinson; Denali |
| Rescue and medical cover | Medical and evacuation insurance is required of every climber and trip cancellation insurance is "highly recommended"; Madison names Redpoint Resolutions, Global Rescue and AIG Travel Guard as providers to consider and provides none of the three itself | Expedition insurance |
| Summit and safety claims | "Celebrating the highest success and safety in the industry 8 years running", with no figures, methodology or comparison given anywhere on the site | About |
These facts are reported because a climber paying USD 50,000 or more should see them before booking; the rubric does not score them for any of the ten mountaineering companies in this batch.
No independent review platform shows a rating for Madison Mountaineering: its Trustpilot page is unclaimed with no reviews, and no Tripadvisor or BBB listing could be found.
A direct search of bbb.org's own listings page was blocked, and no presence was found on Feefo or Reviews.io either. Why cruise and expedition reviews tend to collect on some platforms and not others is explained in our guide to review platforms.
Madison Mountaineering suits a well-funded, self-directed climber who wants direct access to Garrett Madison's own summit record and is comfortable buying insurance and accepting non-refundable terms with no company protection scheme behind them.
Its ladder runs from Kilimanjaro and Aconcagua up through Denali and Vinson to K2 and four Everest tiers, so it suits a climber planning a Seven Summits campaign as much as an Everest specialist. It suits less well a buyer who wants a graduated cancellation scale or a named financial protection scheme, which neither this record nor our Seven Summits operator index found. Choosing a Kilimanjaro route is covered in our Kilimanjaro routes and cost guide.
Whichever Madison Mountaineering expedition a climber books, the card used for the deposit, the flight to the gateway city and the insurance bought are the climber's own decisions.
| Decision | What matters for a Madison expedition | Where we cover it |
|---|---|---|
| Paying the deposit | A USD 25,000 deposit on the USD 79,500 Everest South Col climb is close to a third of the total; the card used decides the purchase cover that comes with it. | Best luxury travel credit cards; Amex Platinum vs Chase Sapphire Reserve |
| Reaching the mountain | Everest and Lhotse departures start from Kathmandu, K2 from Islamabad and Vinson from Punta Arenas; the long-haul seat is the traveller's own choice. | Best business class airlines; best first class airlines |
| Airport time | Long connections through Kathmandu, Islamabad or Punta Arenas are where a lounge pays for itself. | Credit cards with airport lounge access |
| A delayed flight | A delayed flight from a UK or EU airport can carry fixed compensation of up to £520 or €600, though Madison's own charter and guide schedule will not wait for a claim to clear. | AirHelp vs ClaimCompass vs Skycop vs Flightright |
| Nights either side | Everest and Lhotse fares include hotel nights at the Yak & Yeti in Kathmandu; nights before or after other climbs are the traveller's own choice. | Hilton Diamond vs Marriott Titanium vs Hyatt Globalist |
| Choosing the climb | Everest's window runs April to May, Denali in June, and Kilimanjaro year round; compulsory altitude insurance applies to every one of them. | High-altitude trekking insurance guide; mountain destinations worth planning around |
Madison Mountaineering appears on two of our mountaineering pages and holds a ranked position on both.
| Page | Position | Note |
|---|---|---|
| Everest expedition operators (2027) | Priced: South Col USD 79,500, Express USD 85,000, Super Express USD 128,950 | That page gives the Super Express as 18 days; this record finds 19 days on Madison's own site |
| Seven Summits operator index | 5th, 65/100 | A different rubric: it scores what each climb discloses, not what a buyer can check before paying |
The closest alternatives are Alpenglow Expeditions for the highest score among the nine, Adventure Consultants for a graduated cancellation scale, International Mountain Guides for the longest Everest track record, and Climbing the Seven Summits for a price-tiered Everest ladder.
| Company | Record score | How it differs |
|---|---|---|
| Alpenglow Expeditions | 66 | Highest-scoring of the nine; still no financial protection, but a stronger review base |
| Adventure Consultants | 49 | A graduated cancellation scale instead of a flat non-refundable rule |
| International Mountain Guides | 55 | Founded in 1986; publishes no price for Everest itself |
| Climbing the Seven Summits | 41 | A five-tier Everest ladder by price; no phone number at all |
Six things a buyer would want could not be found or verified for Madison Mountaineering. Supplying a verifiable source closes a gap; it changes the evidence, never the rubric.
| Missing | Where we looked |
|---|---|
| A Washington company or UBI registration number, or a seller-of-travel endorsement | Washington Secretary of State and Department of Revenue lookups, both unreachable |
| USTOA membership, a state seller-of-travel number, or a trust or escrow account statement | Expedition insurance page; USTOA directory |
| An independent review platform: no Tripadvisor listing or BBB profile, and an unclaimed Trustpilot page with no reviews | Trustpilot, Tripadvisor, BBB |
| A standalone terms and conditions or booking conditions page | Full site page list |
| A named Nepal outfitter or agency, or a Nepal Department of Tourism licence number for the company itself | Expedition and about pages |
| A guide-to-climber ratio for seven of its nine priced expeditions, and any oxygen bottle count or flow rate | Everest, K2, Lhotse, Aconcagua, Kilimanjaro, Elbrus and Carstensz pages |
The two dated developments found for 2024 to 2026 both concern the wider Everest and K2 seasons rather than Madison itself.
| When | What happened | Source |
|---|---|---|
| 18 July 2025 | A Madison Mountaineering climber, Ryan Mitchell, is separately confirmed safe at K2 Base Camp in coverage of a death on the mountain that season; no link is stated between Madison and the fatality | Alan Arnette |
| 22 May 2026 | A dispatch from Garrett Madison at Camp 2 on Everest, targeting a 25 May summit push; the same piece reports two deaths that season, both tied to other operators, not Madison Mountaineering | Alan Arnette |
Madison Mountaineering is owned and led by its founder, Garrett Madison, president and founder, who states 15 Everest summits and five on K2. Kurt Hunter is listed separately as "Technical Advisor / Co-Founder" on the same staff page.
Four tiers are priced for 2027: the 42-day South Col standard climb at USD 79,500, the Everest and Lhotse combination at USD 98,975, the 30-day Express at USD 85,000 and the 19-day Super Express at USD 128,950. A private ascent is on enquiry.
Coverage varies by peak but typically includes Kathmandu or Islamabad airport transfers and hotel nights, in-country flights, permits, camp staff and guides, and on Nepal climbs oxygen cylinders. International airfare, evacuation insurance and personal gear are excluded.
There is no graduated scale. Every priced expedition states that the deposit and full balance are non-refundable regardless of the reason, including weather or a summit not reached, though Madison says it may waive fees case by case.
No USTOA membership, US state seller-of-travel registration or trust or escrow account statement could be found anywhere on its site. Clients are required to buy their own medical and evacuation insurance.
Nothing independently verifiable could be found: no Tripadvisor listing, no BBB profile and no reviews on its own Trustpilot page, which is unclaimed.
Its own guides lead every climb, and on Himalayan expeditions its own Sherpa team, led since 2015 by sirdar Aang Phurba Sherpa. More than 20 guides are named on its About page, including IFMGA guide Estalin Suárez and WMCI and IPGA guide Scott Webster.
No bottle count or flow rate for any peak. A guide-to-climber ratio is published only for Vinson, four to one, and Denali, two to one. It claims "the highest success and safety in the industry 8 years running" with no figures behind it.
Its score of 65 on our Seven Summits operator index, 5th of 13 ranked operators, is higher than this record's 52 because the index scores what each climb includes and discloses, such as price, guide ratio and oxygen, while this record scores what a buyer can check before paying, such as terms, protection and reviews.
