In 2009, a section of the riverbank collapsed in the middle of the nature trail, and the slope was reinforced with boulders and cover soil.\n\nThe vegetation of the river valley grove and swamp grove is exceptional for the city and partly for the region. The rare touch-me-not balsam, which is uncommon elsewhere in the city, grows lushly along the trail. In early summer, you can often hear the nightingale singing on the trail, and the flute-like sounds of the blackcap echo in the forest. In winter, a few dippers enjoy the Tourujoki River, and woodpeckers can be heard in the forest. Owls are also winter visitors and are occasionally seen. At least the Ural owl, the boreal owl, the Eurasian pygmy owl, and the eagle owl have visited Tourujoki. If you spot an owl resting during the day, please leave it undisturbed and do not approach it unnecessarily.\n\nThe starting point of the trail is just over half a kilometer north of the city center as the crow flies. The information board for the trail and the protected area is located by the river, roughly at the southern end of the old cemetery. The end of the trail and a smaller information board are on Kankaankatu, north of the cemetery. There are nine checkpoint boards along the route.\n\nThe Tourujoki nature trail was renamed Heikki's Trail in June 2016 in honor of Heikki Sihvonen, who served as Jyväskylä's environmental protection planner for 35 years before retiring.\n\nThe principle of litter-free hiking is followed on Jyväskylä's nature trails. Please take your trash with you to sort at home. Walking dogs is completely prohibited in the Tourujoki nature reserve. The nature trail is not maintained in winter, but there are usually enough visitors to keep the trail passable. Be careful on the stairs and boardwalks of the nature trail, especially in slippery conditions!","fi":"Jokirannan jyrkkien törmien ja eroosioalttiin, märän ja liettyvän maaperän vuoksi paikalle on pitänyt rakentaa melkoisia silta- ja porrasrakennelmia. Luontopolun keskivaiheilla jokitörmää sortui alas vuonna 2009, jolloin rinnettä tuettiin louheilla ja peitemailla. \n\nJokilaakson lehdon ja lehtokorven kasvillisuus on kaupungin ja osin maakunnankin oloissa poikkeuksellista. Muualla kaupungissa harvinainen lehtopalsami kasvaa rehevänä polun varressa. Alkukesästä polulla kuulee usein satakielen laulavan, ja mustapääkertun huiluäänet kaikuvat metsässä. Talvisin Tourujoella viihtyy muutamia koskikaroja ja tikat nakuttelevat metsässä. Talvivieraita ovat myös pöllöt, joita nähdään silloin tällöin. Ainakin viiru-, lehto ja varpuspöllö sekä huuhkaja ovat Tourujoella vierailleet. Jos huomaat päivälevolla olevan pöllön, anna sen olla rauhassa, äläkä turhaan lähesty sitä.\n\nPolun alkupää on linnuntietä reilun puolen kilometrin verran pohjoiseen kaupungin ydinkeskustasta. Polun ja suojelualueen opastaulu on jokirannassa kutakuinkin vanhan hautausmaan eteläpään tasalla. Polun loppupää ja pienempi opastaulu ovat Kankaankadulla hautausmaan pohjoispuolella. Reitin varrella on yhdeksän rastitaulua.\n\nTourujoen luontopolku on nimetty kesäkuussa 2016 toiselta nimeltään Heikin poluksi Jyväskylän kaupungin ympäristönsuojelusuunnittelijana 35 vuotta toimineen Heikki Sihvosen jäätyä eläkkeelle virastaan.\n\nJyväskylän luontopoluilla noudatetaan roskattoman retkeilyn periaatteita. Tuo roskat mukanasi retkeltä kotona lajiteltaviksi. Koirien ulkoiluttaminen on Tourujoen luonnonsuojelualueella kokonaan kielletty. Luontopolulla ei ole talvikunnossapitoa, mutta kulkijoita on yleensä sen verran, että polku säilyy kulkukelpoisena.
