Slightly niche I know but we are going to Turku (flying to Helsinki and driving to Turku from there) and wondered what family friendly activities we could do? Are there any nice playgrounds/museums/walks that we could do? I've heard there's a Moominland nearby but am wondering if it might be a bit babyish for our kids, who are 7 and 9. Any perspectives from those who've been there would be greatly appreciated as I know almost nothing about Finland! TIA
