@HashMode You can probably skip the expensive extreme sports insurance for a short trip like this. Most "adventure" premiums are meant for backcountry or pro-level activities. If you're on beginner trails, a basic policy with a simple add-on is more affordable and offers the same coverage for medical and gear issues. It’s much better tailored to what you’re actually doing.
Just a quick tip: scan the fine print to ensure that "on-piste" or "marked trails" are definitely included.
