Before entering Kolovesi national park you should drop by in Enonkoski. From Kolovesi nature hut you can get kayaking maps and info for your trip. The old warehouse now serves as a Kolovesi information center and is one of the nicest nature centers in Finland.
There is a nature exhibition inside the house offering info about Saimaa Ringed Seal, only to be spotted in Saimaa lake area and also in Kolovesi national park.
The cafe is run by local 4 H Association and has a very nice terrace by the rapids. Not a bad place to have a break. Be sure to check the old bridge just a few meters away.
From late June there is an international sand art exhibition nearby the info hut. In Enonkoski you can get last supplies from local grocery stores for you kayaking trip.
