About moving on the waters of Lake Pielinen (from https://www.koli.fi/en/What-to-do/Summer-season/Canoeing-and-boating): The extensive Pielinen is a versatile source of summer fun that can be captured by rowing, canoeing or racing trip on your own. The sandy islands rising from Pielinen and the narrow archipelago stretching south from it are an attractive destination in calm weather. The islands have more campgrounds and  lovely white sand beaches for beach life. 

Please note that the regulations of the Koli National Park prohibit movement on islets smaller than one hectare from 15 May to 17 July for nesting peace of waterfowl. You can find more information on Koli's boat and canoeing destinations and trails at https://www.nationalparks.fi/kolinp
