Compared on 2 treks. Every price below was read on Mountain Madness' own website, on the date shown, and costed the same way as every other operator's.
| Trek | Days | Package | All-in | Where it ranks | Read |
|---|---|---|---|---|---|
| Aconcagua Aconcagua Polish Traverse Route, 21 days |
21 | $9,750 | $11,780 | 12th cheapest of 14 | 2026-09-23 |
| K2 Base Camp K2 Base Camp Trek (Gondogoro La crossing), 25 days |
25 | $9,500 | $10,358 | most expensive of 13 | 2026-09-24 |
All-in is the package plus everything it leaves out (flights to the trailhead, hotel, meals, porter, gear, tips, insurance, visa) at the sourced figures on each trek's page. Where Mountain Madness' page does not say whether something is included, it is counted as extra, so no operator looks cheaper by saying less. No operator has paid to be listed and there are no affiliate links on this site. If that changes, it will say so here.
