The river Oxonica is one of the most interesting and challenging rivers in Karelia. The river basin is located in lake Ladoga. It flows through the territory of pitkäranta and suojärvi district. The river begins at 50 km North from yonkoski, and flows into lake Ladoga near the village Uuksu. The total length of the river is 150 km, and a width of 10-50 m. the Main tributaries of the river are: Kartiki, Insaniac, mustajoki, Urmanski, Wamania. The river Oxonica flows through a sparsely populated area, and on her way to meet only two of the village: Uuksu and Raikonkoski.

A distinctive feature of the river is that it almost meets on his long journey lakes; it is not a chain of lakes connected by canals. The end of the river is accompanied by four super pagename, each harder than the previous one. For riding or training of this kind-rapids waterfalls are not suitable due to excessive power and danger. As to the river for active recreation, Uucsa particularly diverse. The power of the river occurs through swamps and lakes, and its level depends largely on the climatic conditions of the coming season.

The river Oxonica has a third category of complexity. Among tourists of particular interest are the last 15 km of the river, because in this place there are five powerful third threshold or above level. The upper section of the river is not as interesting, but still along there are numerous shiver and simple thresholds. It is best to place the river in the period of high water and flooding from may to June-a month. Means for alloy will suit absolutely any.

The first threshold called the "Pink elephant" or "paw" is considered the main attraction of the river Wuxi. At this point, the river turns right and bifurcates into two powerful stream, one of which tourists have to choose your route. Then, tourists will pass the threshold of "Mill". The ruins of a water mill located on the right Bank. Drops of water are approximately 3 m. Immediately after the "Mill" is the threshold of "Canyon", which is the place where the river is much and dramatically narrows. This place is called that way because the right Bank of the river is particularly rocky and high, and has numerous boulders that order in a chaotic scattered throughout the river bed.

After the "Canyon" will be passed, will need to overcome another threshold "lower mill" or as it is also called "the Temple". Then the river is divided into two parts, the left tributary of a two-stage falls waterfall, which reaches a height of 4-5 m. But due to the fact that the width of the right channel is much wider then on the line with very little water. Most often, this waterfall tourists are not due to the fact that this place is convenient to complete its extreme waterway. The end of the route takes place in the village of Il-Uuksu where from the dam, passing through the river, railway station 800 m.

The river Oxonica required human factor in terms of the abundance of rapids. Until 1917 in the rapids and padonak stood a small hydroelectric power station that provided electricity to all the surrounding towns and villages. During the 50's and 60's, when the Soviet Party, made decisions about the increase of small settlements, the surrounding villages were completely destroyed, and the inhabitants resettled. HPP also blew up. Thus, the habitable edge very soon passed into complete desolation, and on the banks of the river Wuxi even now no signs of any settlements, not counting the village Uucsa area and ends with the greatest number of rafting routes. In addition, in the surrounding areas of the river took place once the border with Finland. Once the war was over, some of the Finnish lands, including the remains of defensive Mannerheim line, passed into the hands of the Soviet Union. In those places are still fortified ramparts, barbed wire and the ruins of the bunker.

More often, the water trip on the river Oxonica leaves not much time 3-4 days, for this reason, river rafting is the most convenient to arrange in a short period of leave or simply be combined with a trip on any other river of the North Ladoga area.
