The Tilleoru nature trail starts in Tilleorg valley and runs for 4.5 km along the area's floodplain before passing through coniferous forests and eventually reaching Merioone spring.
A nature reserve, situated in the headwaters of the Ahja River, on the stretch between Tille and the Möksi; the area's windmill was established in 1957. Founded to preserve the landscape’s integrity, the reserve protects the forests growing on the banks of the Ahja River. With the forests' area covering the nearby valleys, hills and on valley brinks – the entire area is a real jewel of nature.
Did you know...?: People originally believed that Merioone spring reached the sea; this is how it got its name.
