Roiupalu study trail
This trail has a surprising amount of features characteristic of the South-Estonian region: the twisting Hatiku stream, wonderful views of the Ahja River and sandstone outcrops, the only marsh (Linajärve) on the banks of the Ahja River primeval valley, and drawings introducing small mammals.
The trail is marked with orange patches on tree trunks. The trail has moderate technical complexity: it is easy at times, but there is a risk of slipping on the steep slopes. The trail is only suitable for walking.
