Hi Caitriona, Katrina from WorldNomads.com here.
Blatant plug: you can buy a policy online with us, even if you're already travelling.
You will have to upgrade your adventure sport cover to go skiing, so please make sure you check the level of cover required and upgrade it when you buy the policy: http://www.worldnomads.com/travel-insurance/adventure-travel-insurance.aspx
If you have specific questions about coverage, please talk to our customer service team - they're always happy to help: http://worldnomads.com/contactus.aspx
Hope you have an awesome trip. over 4 years ago
