Like many great things in life, Palkkivehmas (or Palkkis, as we locals call it) have its bright and dark sides. The original area in the clearcutting is sunny and hot during the summer. But it makes a perfect spot for starting the season early in the spring or finishing it in the late fall, like many of us do. Unlike the original boulders, the newer sectors (Etiikka, Pianisti) lay in nice shady forests giving an opportunity for some good summer-time bouldering as well.
Palkkivehmas has something to offer for everybody. There are plenty of short easy routes for beginners, lots of good quality 6's and a good amount of 7's for more advanced climbers. Stylewise you name it, Palkkivehmas has got it, from easy slabs to harder testpieces on overhang. Mostly boulders aren't too tall, but there are some higher ones also to get your pulse go a bit higher.
Palkkivehmas is most likely known by its 3-star slab route Comfort Zone, 7A, that puts your technique to the test. But there are some other masterpieces there too, such as:
Master, 6C, a nice short overhang
Pianisti, 7C, and its variations for the ones who have already gained a bit more finger strength
Dirtbag Diaries and Shark Ethics, 6B/+, supernice slabs on "Etiikka" -boulder
Kurki and Äkkihoppu, 6A, both great low-end 6's
Keine Åland and What time is it? It's hawk time!!, 7A/+
You'll just have to go and find out what's your favourite, there's a fair chance that it's some other than the ones mentioned here.
As mentioned the original Palkkivehmas -area is sunny and very hot in the summertime, so don't forget to bring your sun cream with you. There might be some insects as well, so it won't hurt having your mosquito repellent with you too. There are quite a lot of mosquitos in the shadier boulders in the summertime as well.
Note that it is recommended to drive Metsolantie from north, as the southern road is in pretty bad shape.
