The attractive town of Lohja (Swedish: Lojo) isn't on the sea coast, but it is on the coast of Lohjanjärvi – the biggest lake in these parts. The plethora of inlets and islets, and the easy access from the capital, mean that most Helsinki residents seem to have a cottage here. The limestone-rich soil around the lake is ideal for growing apples, and orchards grace the shores. Lohja's wooded environs were also the stamping ground of Elias Lönnrot, compiler of the Kalevala epic.
The settlement itself is a hard-working mining town with a graceful medieval church and a small but interesting museum. It's worth a stop if you're in the area, but its main role for tourists is to keep the lake houses stocked with beer and supplies.
