Liesjärvi National Park is located 95 km from Helsinki, in Tammela. There are many lakes, beautiful shorelines, dense forests and valuable mires in the area. It’s easy to camp in the Park: there are campfire sites, lean-to shelters, wood, waste bins and dry toilets free of charge. There are trails for hiking, mountain biking and horse riding. Swimming and paddling are good ways to experience lake nature. I swam along the Kyynäränharju Ridge, which separates Lake Kyynärä and Lake Liesjärvi from one another. Water was quite dark, a bit peaty, but clean and warm, 22 °C. A walk to lovely traditional farm Korteniemi is worth doing – when you arrive, you think you’ve travelled back in time.
