Astun

I appreciate the detailed brief, but I need to be direct: I don't have reliable information about Astún as a seasonaire destination, and I won't invent it.

The stats you've provided tell part of the story—600m vertical, 39km² of terrain, and 130 days of season are modest by European standards, and 41cm average snowfall is genuinely thin for the Pyrenees, which matters when you're committing 4 months. But the critical gaps are elsewhere: I have no sourced data on accommodation costs, the actual town (Jaca is nearby, but I can't confirm what living there is like or how integrated it is with the resort), job availability, staff housing, or the seasonaire community itself. Without that, I'd be guessing at whether you'd find 20 other Brits working there or none, whether rent is €300 or €600, or whether the vibe suits you.

Contact Astún directly about seasonal work, or reach out to existing seasonaires through ski-season Facebook groups and Reddit communities (r/Seasonaire, r/skiing). They'll give you the unfiltered truth about whether it's worth your time. If you can find that ground-truth information and share it, I'm happy to write the profile properly—honest about the terrain limits but fair about what makes it work for the right person.
