Well, at the moment, I am still in discovering mode.
Nothing really super exciting for an advanced packrafter probably, but at my neophyte level, I find everything fun.
I am currently exploring my region (Satakunta, south west Finland) and the possibilities offered by a packraft. Finland has a lot of water anyway… Maybe not everything is interesting, but finding a nice hiking/rafting route is not the most difficult task here, from short to week long trips.
I found this document http://reitti.org/eng/ar_eitavallinen.php and I am planning to paddle along these rivers for the next few weekends.
Poosjoki sounds nice.
I don’t know if you’re into ‘‘big’’ rapids (which means for me class 3 and above). They might be a bit hard to find here in Finland.
But since I am sticking to what I feel capable of doing at the moment (class I and 2), I can say that there are numerous route of 60km+ with these class of rapids.
When I will have more time for myself, I will rather explore the north of Finland where water routes are more into the wilderness. Some ideas: There is a 700km+ route between Kilpisjarvi and Tornio which follows the swedish-finnish border. Might be fun to follow a part of it.
Vatsari wilderness area might be fun to explore too. (http://www.luontoon.fi/page.asp?Section=5697). (check the ‘‘Lars Monsen nordkalotten 360’’ last season -season 8 I recall- on youtube)
Also, there’s some famous rivers in the Oulanka national park which might be fun for when I will be more experienced.
