Vaasa is a small town with a population of 67.000 souls on the west coast of Finland. The area is more or less flat with the exception of Öjberget, which is located about 5 km outside of Vaasa where you can go downhill and cross-country skiing.
If you are interested in climbing, then you can give it a try in the water tower of Vaasa – straight in the city centre next to the tourist office.
For those who like hiking trips, a ride to Björkeby or Öjen (40km north of Vaasa) might be an option to enjoy the Kvarken Archipelago – an UNESCO world heritage site. kvarkenworldheritage.fi is a good website to find more information about the Kvarken Archipelago. Unfortunately, public transportation is quite bad in the Vaasa region so having a car or taking a taxi is more or less the only way to get there (or with a bicycle if you are still in the mood to hike once you arrive there).
If you come with a group, you should check Reino Tupa. They have a great kitchen, Sauna and possibilities to do quad biking.
Other options which around Vaasa are to visit bird towers or Kajane – a swampy area south of Vaasa.
Replot – the longest bridge in Finland
If you are more into packrafting, the Bothnian Sea or Pilvilämpi are great spots to inflate your boat.
To learn more about the area and in particular the Kvarken Archipelago, a visit to Terra Nova – a museum in the city of Vaasa is highly recommended. Entrance is free of charge on Fridays.
