City of Hyvinkää – Kolmen lammen kierros+

Description

For closures, forest-fire rules, and the step-by-step route narrative, start with hyvinkaa.fi. The Kytäjä–Usmi area page frames the wider trail network and nature values. Retkipaikka’s Luontopolkumies walkthrough adds practical notes on markings, wet sections, and where the path shares forest roads with other routes. Toisiin maisemiin describes the Piilolammi lookout rope descent, mixed blue and yellow markings there, and how easy it is to miss turn-offs when forest roads double as winter ski corridors. The trail is about 7.1 km as one continuous line on our map. The City of Hyvinkää publishes a longer figure of about 9.8 km for the full marked circuit beginning and ending at Usmin beach parking, including road links and the classic three-lake loop through Piilolammi, Iso-Kypärä, and Kaksoislammit. The route is classed as demanding: rocky, rooty forest paths, wet hollows and mire, and noticeable ups and downs, with a rope on the steepest climb to the Piilolammi viewpoint. Marking is mainly blue paint on wooden posts; near Piilolammi, yellow markings appear briefly where the path drops toward the shore. From the Usmin end of the circuit you are close to Usmin uimaranta and Usminjärven talviuintipaikka. Early along the line, Piilolammi Uimalaituri, Usmi Piilolammi laituri, Piilolammi Tulipaikka, and Piilolammin Tulipaikka cluster around Piilolammi—good for a swim stop or a short detour onto Piilolammin luontopolku. About 1 km in, Iso-Kypärän laavu sits above Iso-Kypärä; farther on, Latu-Miilun maja and Kaksoslammien laavu bracket the twin-lake area, with Iso-karhun Outdoor Grill and Iso-Karhun nuotiopaikka nearby on shared tread with biking routes. Dry toilets sit near Piilolammi (Usmi Piilolammi kuivakäymälä). Piilolammi parkkipaikka offers parking partway round if you approach from that side. The circuit shares junctions with Kahden piilon kierros, Kytömetsän pyörähdys, Kypärän lenkki, Kiiskilammen takalenkki, Karhujen pyörähdys, Usmin lenkki, and longer hikes such as Mustan kiven kierros and Seitsemän veljeksen vaellusreitti; near the finish, Vaskivuoren luontopolku branches toward the beach. Hyvinkää in Kanta-Häme is a straightforward base for day hiking in the Kytäjä–Usmi forests.

Good to know

Keep dogs leashed year-round on this route. No winter maintenance for the hiking trail itself, but some sections overlap Hyvinkää’s ski trail network in winter. Do not light fires during forest fire warnings; carry water for extinguishing campfires when allowed. Red-throated divers may use Iso-Kypärä; observe nesting birds from a distance.
