The total length of the hiking trail in the primeval valley of the Piusa River is 15 km – from the ruins of the Vastseliina Episcopal Castle to Lindora or vice versa. You can take the trail on foot, but parts of it are also passable either by bike or car. The greatest values of the reserve are the 12 Devonian sandstone outcrops – the highest is the wall of Härma Mäemine (total height 43 m). There are two camping sites – under the Make Wall on the first third of the trail and under the Härma Lower Wall towards the end of the trail.
