The Aegviidu to Nelijärve trail is one of the classic day walks in Kõrvemaa, the forested sand-ridge and bog country in the eastern part of Harju County, Estonia. The route begins at Aegviidu railway station in Anija Parish, which is served by Elron commuter trains from Tallinn's Balti jaam in about an hour, so no car, parking or permit is needed. Marked paths maintained by RMK, the State Forest Management Centre, lead roughly 10 to 12 kilometres north-east to the Nelijärve holiday area, a trip that usually takes three to four hours one way at an unhurried pace. The distance is well within the easy category: total climbing is under 50 metres, and the main effort comes from soft sandy sections and the length of the walk rather than any steep terrain. The surface alternates between forest dirt tracks, sandy ridge paths, short stretches of gravel and wooden boardwalks across wet ground. Pine forest provides shade for much of the route, although open bog edges are exposed to sun and wind. There is no technical exposure. Along the way walkers pass small forest lakes, mossy bogs, glacial hills and dense stands of pine and spruce, typical of the Kõrvemaa landscape. Nelijärve itself is a recreation area on the shore of a chain of lakes, with a beach, a sports and holiday centre and picnic spots, which makes it the natural turn-around or rest point. Because water sources along the trail are not reliably potable, visitors should carry all the water they need. RMK maintains fireplaces and rest stops with benches in the Kõrvemaa area, and these can serve as shelter breaks, but there are no staffed mountain huts. Ticks are common in warm months, so long trousers and a tick check afterwards are advisable. Mobile coverage is generally adequate but a downloaded offline map helps at forest junctions. Walkers who do not wish to return on foot should check bus and taxi options from Nelijärve before setting out, since services are limited, and should plan the return train from Aegviidu with a margin for the final stretch.
