Signs of spring at Punatulkku and Pohjantikka trails in Liesjärvi

Punatulkku and Pohjantikka trails at Liesjärvi National Park

Punatulkku and Pohjantikka trails in Liesjärvi National Park are located near Korteniemi Heritage Farm. Punatulkun polku, Punatulkku trail, is a 3,1 kilometers long circle trail that departs from parking area called Lehdos situated along Korteniementie road. Pohjantikan polku, Pohjantikka trail, is a 5 kilometers long circle trail that departs from Korteniemi parking area. You can also combine these two trails easily into one 6 kilometers long trail like we did in April.

Punatulkku trail at Liesjärvi National Park

We began our walk from the Lehdos parking area by heading to Punatulkku trail anticlockwise as recommended. I was wondering about the condition of the trails and whether they would be too soft to walk on, but Punatulkku trail was mainly dry. There was some ice, but the trail was easy to walk on. This trail leads you through a relatively young pine forest to Liesjärvi lake shore and to Korteniemi Heritage Farm.

Korteniemi Heritage Farm’s exciting sign of spring

There are farm animals living at Korteniemi in summertime but now sheep pasture was empty. Or almost empty. We did spot an exciting sign of spring by the side of the trail near the pasture; a viper was soaking in the sun! The viper (Vipera berus), also known as adder, is the most common poisonous snake in Europe, and the only poisonous one in Finland. You can recognize it from a dark and very distinct zig-zag pattern down its back, and red eyes. Early spring is a good time to spot them when they come from hibernation to soak in the sun and began mating. Since we had one dog with us, we carried the dog past the snake so they could both continue their day without any danger and disturbance.


As the Korteniemi Heritage Farm is best to explore in summer, we continued along the trail towards Pitkäkärki. We passed signs to Ahonnokka, which is the shortest 1,3 kilometers long circle trail (green) from Korteniemi.

Korteniemi is also connected to Hämeen Ilvesreitti and the rest of the trails at the national park by yellow trail.

Pohjantikan polku / Pohjantikka trail 5 km (blue)

After Korteniemi, we passed a cow pasture and spotted the Liesjärvi lake on our right-hand side again. Here Liesjärvi lake still had some ice in it. Then we came to an intersection where the blue Pohjantikka trail departed from the red Punatulkku trail towards Pitkäniemi. Since the trail had been in such a good condition, we decided to take a little detour to Pitkäniemi along the blue Pohjantikka trail. Duckboards were dry and in good condition.

Pitkäniemi is an ancient place of residence from the Stone Age. Imagine how many generations of people and adders have wondered in these forests before you. At Pitkäniemi we found a small field and a barn. The blue trail turned out to be quite wet and challenging at times. The Pohjantikka trail consisted of old pine forests and also many fallen trees to climb over. One of them seemed to be squirrels’ lunch table.

Our last section of the trail was again the red Punatulkku trail, which took us over a small ridge and back to Lehdos parking area.

  1. Wow, you lucked out spotting the adder! Or maybe luck isn’t the word haha, if it was me I would have been scared. Looks like you chose a great time to go, the weather looks perfect and not too much snow; maybe more quiet and peaceful than in the summertime too. How do they know this area is an ancient residence?

    1. Jenni says:

      Good question! Some traces of habitants as well as their tools have been found from the beaches of Liesjärvi. Quartz and flintstone finds have been dated back to the Stone Age, and Finnish Heritage Agency lists Liesjärvi as Stone Age residence. Thanks for your comment, Claire!

  2. Karen says:

    It is so rare to come across an outdoor blog from Finland so I was happy to read about the beautiful areas there. I’m glad the dog and the adder found some distance from each other. I know my dog would stick his nose right into it.

    1. Jenni says:

      We were so lucky that we saw the adder before the dog!

  3. Alisha says:

    It’s so nice how the Punatulkku trail takes you from pine forest to lake shore to farm. I’d definitely visit when the farm is open.

    1. Jenni says:

      The farm is indeed fascinating with all the cute animals and old-fashioned ways of doing the daily chores. Thanks for you comment, Alisha!

  4. Josy A says:

    Oooh nice! The Punatulkku and Pohjantikka trails both looks so relaxing and gorgeous at this time of year and spring creeps in and melts those last vestiges of snow. I love all the reflections in the lake and it is sooo cool that you saw the viper!
