Juveninkoski rapids are part of the Nytkymenjoki River. It is the highest and steepest known free waterfall in Central Finland. The height of the waterfall is over 7 meters. Especially, during the spring floods, it is a magnificent sight. In summer, a sharp pathway leads to the downstream. It begins at the Partalantie road, behind the guardrail. The local village society of Partala has built a parking area, information sign, an observation post, and a resting place with mill stones on top of the waterfall, beside the road. Not far from the waterfall, downstreams, there is a small swimming pond.
