Haukankierros Trail, Haukkalampi (Nuuksio National Park)

Haukankierros is a 4 km circular trail that starts from the Haukkalampi trailhead in Nuuksio National Park, Espoo, in the Uusimaa region of Finland. The trailhead is at Haukkalammentie 32, roughly 35 km from central Helsinki. Public transport access uses an HSL train to Espoo station and then bus 245 or 245A to Punjonsuo or Nuuksionpää, followed by a walk to Haukkalampi; the car park at the trailhead serves drivers. National park entry is free and no permit is needed for day walks. The loop takes about two hours and sits between the short Punarinnankierros and the long Korpinkierros in length. The trail is marked as challenging for its height differences, but the climbs are short and the total distance keeps it within reach of most reasonably fit walkers, which is why it is classed here as easy to moderate. The surface alternates between forest soil, roots and bare rock ridges, and the rock becomes slippery when wet. Forest cover provides shade for much of the route, while the ridges open up to views of small lakes and pine forest. Landmarks are the rocky ridges themselves and the ponds around Haukkalampi, where the walk begins and ends. Because the loop is short and returns to the trailhead, no formal turn-around point is needed; walkers who feel tired can simply follow the signs back. There are no staffed huts on the trail, and drinking water should be carried from the start. Marked cooking sites in the wider Haukkalampi area allow fires only in designated places. The route is a practical half-day option for visitors who find the 8 km Korpinkierros too long but want more than the 2 km family loop. It is also hikeable in winter, when grip soles or light traction aids help on icy rock.
