The Kotka hiking trail showcases different types of bogs and other wetland features. It passes by a sand ridge which developed over thousands of years as the result of the retreat of Lake Peipus. The transition the landscape makes to marshland is sudden and provides an interesting contrast for hikers. Following the boardwalk, you will see all manner of wetland features, from turf and hollows to bog pools and small lakes. At the mid-point of the trail are a cabin and a traditional Estonian structure, similar to a tepee, known as a ‘summer kitchen’. The trail begins in Iisaku and ends in Rüütli bog in the village of Alliku. It is 8 km long in total, although there is also a shorter, 1.5 km boardwalk in the Rüütli bog.
