Oulanka Things to Do
At the main entry to the Oulanka National Park there is park reception and information. There is also cafe and canteen where you eat typical Finnish food as well as you can buy some food & drinks for the road.
I got to Oulanka National Park by my own car. The road is not paved but you do not need 4WD on such road, any normal car can make it if you don't over speed. Be aware that in the winter it might be another story.
Oulanka Warnings and Dangers
I don't think there are major warning or dangers things here. Basic outdoor safety rules apply here as well, watch out your step and beware of low wet places and the water all around. Oh yeah, you might also get lucky and spot a bear, but those are very rare.
Oulanka What to Pack
Good shoes, outdoor cloths, mosquito...
Clothing/Shoes/Weather Gear: I would say that these are not must but surely more comfortable to have hiking shoes and outdoor cloths. In warm summer day you can surely hang around also with sandals but it also might be raining and cool, so be prepare for that as well.
Toiletries and Medical Supplies: Mosquito Repellent can be helpful, depends on the season you visit, during the mid summer period it will be very useful to have such.
