Description

Sonninmäki nature trail is about 1.8 km as one walking line through Sonninmäki in Hyvinkää, Uusimaa: a short municipal path on the Salpausselkä edge between everyday neighbourhoods, linking the Puolimatka school belt and the Vehkoja school belt rather than a remote backcountry hike. For how Hyvinkää marks its nature trails, online maps, and the printable brochure, start from Hyvinkään kaupunki. The same network is also pointed to from Luontoon.fi under the Sonninmäki destination, which pulls Hyvinkää’s outdoor layer together with other national outdoor information. Hyvinkää’s environment pages highlight a downloadable environmental education pack focused on Sonninmäki for schools alongside the wider set of trails. The walk is useful as a family-friendly segment: roughly midway you pass the Puolimatkan koulun lähiliikuntapaikka cluster, and toward the finish the thread nears Vehkojan koulun lähiliikuntapaikka and Vehkojan palloiluhalli—handy if you combine the path with playgrounds and ball fields already on our map. In winter the ridge is better known for skiing: Hyvinkään kaupunki describes Sonninmäen–Nikinharjun ski circuits, lighting hours, limited motor parking, and schoolyard access after the school day from the same landform. You can extend the day on paths that share nodes with this line. Where the geometry touches other maintained routes, our page also sits next to Puolimatkan lenkki, Sonnimäen ulkoilureitti, Puolimatkan maastopyöräilylenkki, and Eteläinen yhdyslatu, while the long Hyvinkään pyörähdys cycling ring shares some of the same junctions. Nikinharjun ulkoilureitti and related ski loops sit a few hundred metres aside for runners and skiers who want a longer loop. Suomen luonnonsuojeluliitto repeats the seven-trail basics—yellow blazes, Retkikartta.fi—and asks visitors to report damaged structures. A 2017 Aamuposti item on volunteer work parties opening the season flagged Sonninmäki among the first work sites as Hyvinkää expanded its nature-trail set.

Length & route

The mapped hiking line is about 1.8 km and is not a loop. Hyvinkään kaupunki publishes a bilingual PDF brochure and points walkers to Retkikartta.fi for mobile following of all municipal nature trails marked with yellow paint blazes.

Getting there

Use the City of Hyvinkää nature-trail page for downloadable maps and the city brochure; Retkikartta.fi carries the same trail layer for phone navigation. Motorists should expect tight parking on the ridge: for the neighbouring ski network Hyvinkään kaupunki recommends the end of Pikkulukontie 4 and, outside school hours, schoolyards serving Puolimatka and Hyvinkäänkylä—reasonable reference points when you piece together access to Puolimatka and Vehkoja on foot. Lights on illuminated winter trails run to 23:00 with possible 05:00 start-ups, which helps if you arrive early or finish late in season.

Good to know

Hyvinkään ympäristöfoorumi links a Sonninmäki-focused school education PDF and the main trail index. If you notice broken structures along municipal nature trails, Suomen luonnonsuojeluliiton paikallisyhdistys asks for direct feedback through its Hyvinkää pages.

History

A May 2017 Aamuposti report described volunteer work parties to open Hyvinkää’s spring nature-trail season, with Sonninmäki scheduled as one of the first sites, in a wider effort to complete seven nature trails for residents and visitors.
