This is the north of Lapland, where the reindeers are very common and you will see them just about everywhere and all the time.
The region is wonderful area for hiking, trekking and other outdoor activities. There are few trails to walk for a day as well as long trekking up to 100 km.
Other way to move from one place to another here is by boat. From Sevettijärvi you can continue north east to Jänisjärvi and Kirakkanjärvi further on is Vuortijärvi and then Jääjärvi just by Näätämö on the border with Norway.
*Not sure if they are all connected, if not, you might need to carry your boat on your back sometimes ;-)
The best way to get here is by having your own car or rented one. The public transport passes only few times a day and will be very inconvenience in such area.
Jääjärvi is the small lake just before you arrive to Näätämö on the Norwegian border. That also will be your last chance to do some shopping for reasonable prices before you cross the border to Norway ;-)
Favorite thing: This region goes from Sevettijärvi to Näätämön on the Norwegian border. On the way you can see Jänisjärvi, Kirakkanjärv and other smaller lakes.
