Punarinnankierros Trail, Haukkalampi (Nuuksio National Park)

Punarinnankierros is the shortest and easiest of the official loop trails from the Haukkalampi trailhead in Nuuksio National Park, Espoo, in the Uusimaa region of southern Finland. The loop is about 2 km long and takes roughly an hour, which makes it a common choice for families with children and for visitors with limited time. The trailhead is at Haukkalammentie 32, about 35 km from central Helsinki. Without a car, visitors take an HSL train to Espoo station and then bus 245 or 245A to Punjonsuo or Nuuksionpää; depending on the stop, the walk to Haukkalampi is between roughly 100 m and 2 km. A car park is available at the trailhead. Entry to the national park is free and no permit is required. The terrain consists of gentle forest paths with only small rises, so elevation gain is minimal. The surface is mostly packed forest soil with some roots and occasional stretches of rock, and the route is well signposted. Tree cover gives shade through most of the loop and shelter from wind. Landmarks are the quiet forest scenery and the small lake at Haukkalampi near the start; there are no summits or exposed sections. Because the loop is short and circular, there is no need for a turn-around point, and walkers can leave the trail at any time by following the signs back to the trailhead. There are no staffed huts or reliable water sources on the trail, so a water bottle from the start is sensible. Open fires are allowed only at designated cooking sites in the area. Walkers who want a longer outing can combine this loop with, or switch to, the 4 km Haukankierros or the 8 km Korpinkierros, which share the same start. The trail is usable year-round, including in winter on snow-covered paths.
