Tips for Planning Your Day Trip from Helsinki

• Best season for islands: Summer is ideal for island connections and harbour life.
• Mix & match: Choose one “town block” (Loviisa / Kotka / Hamina) and one “nature block” (island or ironworks + hike) for a balanced day.
• Want more time? Many travellers turn this into an easy overnight trip — but even a single day gives a rewarding taste of the East Coast.
