125 places reachable without changing, across 1 terminal and 1 airport. 4 of them you can reach more than one way — where the mode is a genuine choice rather than the only route. You do not board anything in Mariehamn itself; each one below says how far out it is.
2 places to board, none of them "Mariehamn" itself. The distance is from the centre — an airport an hour out is a different journey from one thirteen kilometres away, and folding that into a flight time is the false claim this site exists to avoid.
4 places reachable from Mariehamn more than one way. Everywhere else, the mode is not a decision — it is the only way there.
Every destination from Mariehamn placed by compass bearing. Not a map — the angle is the only geography kept, so an empty quarter means nothing goes that way, not that it is sea.
