I have lived in Vaasa for 2 years. The area around Vaasa is quite flat and there are a few places which are worth visiting.
Björköby is located 20 km north of Vaasa and was originally an island before it got connected with the longest bridge in Finland to the mainland. I went with the bicycle from Vaasa to Bjököby, where I planned to visit the Kvarken Archipelago – a UNESCO World Heritage site. 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. The distance to the Swedish mainland is just about 80 km, and the water depth is about 25 meters. The land here is rising at about 1 cm a year. The distance to Björköby is about 40 km from Vaasa. In Björköby is also the Saltkaret observation tower.
Kajane is a nice place to go hiking and is located South of Vaasa, where I also found serviced fireplaces. The trail which leads to lake Lisansjön is called Lillträsket or in Swedish Lilla Naturstigen and went through a swamp area.
Öjberget is a small ski hill nearby the village of Sundom. If you live in Vaasa and want to enjoy nice scenery or do some downhill, cross-country skiing, or snowboarding, you should visit Öjberget. The hill is 45 m high and has a length of 325 m. There is also an observation tower on top of the hill. Further, you can find a 5 km long cross-country ski run which is also lighted in the evening. 4000 years ago, the hill was an island 30 km away from the shore. I often visited Öjberget from Vaasa on my bicycle. The distance is approximately 10 km from the city centre.
Öjen is located between Vaasa and Sundom and can easily be reached by car or bicycle. The trail has a length of 5 km, and there are around 130 different nesting species. The trails are well-maintained, and there is also a fireplace.
In case you are interested in packrafting, you could visit the Pilvilampi lake, a recreational area nearby Vaasa, and a paradise for birdwatchers.
Approximately 5 km south of the Vaasa city center, there is a possibility to hike in Risö and observe birds from a bird tower. There is also a fireplace nearby the bird tower, but you have to bring your firewood.
Söderfjärden is located about 10 km south of Vaasa and a meteorite crater that I visited with my bicycle.
Old Vaasa is also an interesting place to visit. There is, for example, the old court of appeal and a monument from 1808 when Russian forces occupied Vaasa.
