Description

The Piilolammi nature trail is about 1.8 km in the Kytäjä–Usmi forests near Hyvinkää. For how Hyvinkää lists its seven marked nature paths (yellow paint in the field, retkikartta.fi for mobile follow-along), see the City of Hyvinkää nature trails page. The Piilolammi shore destination itself sits on UUVI’s Piilolammi recreation parcel: services, forest-fire rules for the fire pits, dog rules, winter access, and an accessibility note for the shore route are spelled out clearly there. Retkipaikka’s Luontopolkumies walk from 2018 adds boots-on-the-ground detail on ropes on the steepest rises and falls, how the path mixes easy shore walking with rockier ridges, and how busy the parking can be on a summer Saturday. Outdoor Family’s family-focused write-up highlights the gentle approach to the lake edge for picnics and swimming after the barrier-free first section. Start from Piilolammi parkkipaikka at the end of Piilolammintie. A wide track leads toward Piilolammi Tulipaikka under the west cliffs—worth a stop before you climb—while Piilolammi WC sits very close to the early lakeshore bend. On the north shore, Usmi Piilolammi laituri, Usmi Piilolammi kaivo, and Usmi Piilolammi kuivakäymälä cluster together for a swim, a hand pump, and a dry toilet away from the busiest southern shore. Piilolammin Tulipaikka at Piilolammintie 162 and Piilolammi Uimalaituri wrap the short circuit at the south end with a second campfire setting and a swim dock. Dry toilets are available along the approach and at the north shore so you are not hunting for unnamed buildings in the trees. Official copy classifies the nature path as demanding overall because of height differences and uneven footing even though the first approach to the lake is easy going. Expect roots, stone, and short rope assists on the rougher banks. The pond is deep and clear enough for a swim in summer; UUVI reminds visitors to light fires only at marked pits and to obey fire bans entirely when warnings are in force. From the same trailhead you overlap longer hikes—Kolmen lammen kierros and Kahden piilon kierros pass through Piilolammi—while Kytömetsän pyörähdys runs nearby for mountain bikers and winter ski loops such as Kypärän lenkki and Kiiskilammen takalenkki sit the same recreation network. Hyvinkää lies in Uusimaa and is an easy day-trip destination from the Helsinki region.

Length & route

The trail is about 1.8 km as mapped here. Brochure text cited on municipal and UUVI pages often rounds the nature-path circuit to about 2.3 km around Piilolammi. The City of Hyvinkää classifies the route as demanding despite a gentle approach to the shore.

Getting there

Drive Finnish national road 3 toward Hämeenlinna, turn west onto Kytäjäntie at Hyvinkää for about 4.5 km, turn right onto Jauholammintie for about 300 m, then left and follow Piilolammintie to the end to Piilolammi parkkipaikka. The City of Hyvinkää publishes the same sequence for this trailhead together with other nature trails. The access road and parking are ploughed in winter but can be icy.

Good to know

Dogs must be kept on a leash. Fires only at marked pits; during forest-fire warnings fires are banned even at the pits. Boulder problems are described on the cliffs near the parking on UUVI’s page.
