I flew paragliders for nearly 15 years but finally gave up when I came back to Finland for the 2nd time having spent a year in Switzerland, and I have to tell you flying in Finland is a pain in the ASS!!!!
As already mentioned 95% of flying is done from tow launch, with the remainder being cliff hanging in gale force winds
Unless you are 100% committed to flying every time the weather is even remotely suitable you will spend years trying to clock up the hours you need for your permit.
And don´t forget, if you learn in Finland you will have a tow endorsement, which means you won´t be permitted to hill fly unsupervised in most of Europe
If you really want to learn to paraglide, and it is a fantastic sport, I suggest you go to the French or Austrian Alps as many weeks each year as you can, get your permits there and then just get the tow endorsement in Finland when you are qualified.
Switzerland is a fantastic place to fly, but getting your license there isn´t possible unless you are a resident.
