Description
For the national trail listing and this route’s own page, use Luontoon.fi. The loop lies in Pyhäjoki, North Ostrobothnia, on the Bothnian coast. Pyhäjoki is a compact coastal municipality; Rautiperä is its main outdoor hub in Etelänkylä. The City of Pyhäjoki publishes day-to-day details about the ski lodge, lighting on the short circuits, the disc golf course, and seasonal rules for dogs and the rifle range.
The trail is about 16.9 km as one full circuit through forest roads and paths, with red markings and easy going under normal conditions. Some printable overview materials describe the same itinerary at roughly 18 km depending on how the network is measured. Official route notes highlight Pyhäjoki’s historic Isosilta bridge (from 1837), the Rautiperä lodge area, wind turbines at Puskakorpi, and the river flood embankment along Pyhäjoki. Take extra care at busy road crossings, especially Oulaistentie (road 787) and Etelänkyläntie.
The shape links the wider Pyhäjoki trail network: near the early kilometres you can join Viirretjärven lisäreitti and Viirretjärven reitti, branch onto Kupuliskosken reitti toward the rapids kota sites, use Pirttikosken yhdysreitti and Pyhäjoen penkkatiet as cycling connections, or continue toward Halusen reitti along the river. Closer to Kielopuisto you meet Saaren lenkki, Rautiperän lenkille siirtymä, Kielosaaren luontopolku, and Tervon reitti around the sports island and bird tower. At about 13.6 km you pass Kielopuiston kota, then follow the connector into the Rautiperä service cluster: Rautiperän laavu, Rautiperän uimapaikka, Rautiperän avantouintipaikka, Rautiperän grillikota, Rautiperän hiihtomaja, Pyhäjoen ampumahiihtoalue, Rautiperän Frisbeegolf, and Hiihtomajan ampumarata—together a full-service shore and lodge area for breaks, swimming in season, winter swimming where operated, disc golf, and biathlon training infrastructure. Rautiperän kuntorata and Rautiperän valaistu latu overlap the same hub for running and skiing on shorter marked loops.
Length & route
The trail is about 16.9 km as a single loop with red paint markings and mostly easy terrain on roads and paths. Printable municipality maps sometimes round the same circuit to about 18 km. Sights called out in official materials include Pyhäjoki’s Isosilta, the Rautiperä lodge and sports area, Puskakorpi wind power, and the river flood embankment. The Rautiperä centre also hosts shorter illuminated route bases (1 km, 2.5 km, 4 km, and 5 km) that are groomed ski tracks in winter and used as walking bases in summer; those are separate from the full lenkki but share the same trailhead services.
