Finland has plenty to offer for kids. For one, the country has a whimsical streak — Moomin, a unicorn-like mythical creature created by a Finnish cartoonist in the midcentury that's practically the national mascot. The city is also walkable, easy to navigate, full of cafes, and has plenty of adventures toddlers and adults will love. Make sure to take a ferry to Suomenlinna, a fortress from the 18th century that's connected across several islands by bridges. An underground play space called Leikkiluola is also a must-do for toddlers.
