- Data for the trip: a United States eSIM covering about 7 days, the ski days plus a travel day either side. Lift apps, trail maps and avalanche bulletins all need it.

Methodology
How we did this comparison
Mountain statistics come from each resort's own facts page where it publishes one, otherwise from Skiresort.info's trail-map data, and every figure links to its source. Pass access for the 2026/27 season comes only from ikonpass.com and epicpass.com, read on 26 October 2026; check the operator's page before you buy, because access and blackout dates can change.
Days to ski every marked run, how long to stay and how many days of data to buy are our own estimates, not resort figures. We assume a confident intermediate covers 35 km of marked piste in a full day, lifts included, and add a travel day either side for the eSIM. North American resorts publish skiable acreage rather than piste length, so where we rank them we rank by skiable area.
