I have 2 weeks holiday from work this October and I really want to go and do some hiking in Finland (I live in Israel, would love to escape the heat). what I would like to do is several 2-3 days hikes to see some nature, lakes and great views. from what I've read so far Finland has about 35 national parks, which is great. the thing is, it seems that I have to carry everything with me, sleeping gear, food/cooking gear etc. and I really don't want to do that. what kind of facilities are available at the national parks along the trails? I'm looking for a place to sleep (I can skip a few showers if I have to) and to buy some food (nothing fancy). is that possible, or do I have to bring everything with me?
