Description
Hakalaukunlenkki and the shorter Hakalaukunpolku shortcut are part of the Salpausselkä Trails mountain-bike network in Lahti, on moraine ridges and forest ground typical of the ice-age Salpausselkä landscape. For mountain-bike-specific guidance, markings, GPX, parking links, and how the shortcut differs from the main ring, start from City of Lahti’s Hakalaukunlenkki page. Visit Lahti introduces Salpausselkä UNESCO Global Geopark and how the First and Second Salpausselkä ridges read in the Lahti region. City of Lahti’s Salpausselkä Trails overview explains roughly 25 km of marked forest trails around the Sports Centre–Tapanila–Hakalaukku–Kintterönsuo band for year-round walking, running, and mountain biking, dogs on a leash, and winter use such as fat biking or snowshoeing when snow is deep—without using groomed ski tracks for walking.
On our map this route follows about 7.4 km as one continuous line. The City of Lahti describes the main Hakalaukunlenkki ring at about 7 km with roughly 100 m of ascent, violet arrow markings, and a recommended counterclockwise direction; typical ride times are about 1–1.5 hours by mountain bike. Hakalaukunpolku shortens the circuit to about 5.3 km and roughly 70 m of ascent, with dashed violet arrow markers on the shortcut; the northern part can be ridden as about a 2.4 km mini-loop, and the shortcut passes a wetland view, short duckboard, a small rock outcrop, and a picnic table. From Sykekatu the line rolls across Tapanila pine forest, climbs through spruce on Hakalaukunmäki with rooty tread and short rocky pinches, then returns on flowing needle-carpet paths, with a couple of short duckboard sections and a short newer trail segment. You need a mountain bike and basic off-trail skills; ordinary city bikes are not suitable. When you follow the marked counterclockwise direction, the city states there are no highly technical descents and climbs are short enough to walk if needed; the dense trail mesh and ski-track crossings mean keeping speed moderate and using a bell or voice so others hear you. Walkers and trail runners share the same narrow paths with many cyclists summer and winter, so headphones are discouraged. A community-uploaded trace on Jälki.fi lists about 7.05 km and 72 m ascent for a similar Hakalaukunlenkki MTB line starting from Sykekatu.
Near the Tapanila end of the line, about 6.6 km from the Sykekatu-side start, you pass Tapanilan ulkokuntolaitteet and Tapanilan hiihtomaja—useful landmarks if you link to Tapanilan taival - Salpausselkä trails MTB, Kintterön kymppi - Salpausselkä Trails MTB, or the parallel hiking variants, including Hakalaukunlenkki ja Hakalaukunpolku - Salpausselkä Trails and Tähtipolku - Salpausselkä Trails. The route also meets Hollola’s Suoreitti in places, marked with wooden posts and yellow paint blazes. Lahti lies in Päijät-Häme.
Good to know
Dogs must be on a leash on marked Salpausselkä Trails. In winter, groomed ski trails are for skiing only; cross carefully where permitted. When snow is deep, forest trails can be used on foot, with a fat bike, or with snowshoes—do not walk on ski tracks. Forest trails are not lit; markers are reflective, and a headlamp and bike lights are recommended after dark. City of Lahti’s Hakalaukunlenkki page states the route is not barrier-free.
