On foot

 The best way to discover the Adventure Land is to use Penijõe-Aegviidu-Kauksi hiking trail created by RMK, which runs through the whole county and crosses the border of Ida-Viru County at Sonda on Lake Uljaste. It is convenient to start, e.g. from Kiviõli, where you can get from Tallinn by train and move further along the route, or, if you come from Tartu, you can start from Kauksi. You can see the whole route with all resting and campfire sites HERE: https://lingid.ee/j4oeT
