Finnträsk beach is located on the northern shore of the lake of the same name. The district is, I believe, Sarfvik. From an Espoo perspective, the beach is very close, with perhaps two and a half kilometers to the bridge marking the Espoo-Kirkkonummi border.

The beach is in its natural state, featuring smooth rocks, sandy bottom, and fairly shallow water. Be mindful of the large stones that you wouldn't want to bump into.

There is some housing along the shores of the lake, and I believe there are also cottages. The developing Sarfvik area will be very close, making this the nearest beach for many.

There's a nice outdoor trail running parallel to the beach.

The beach seems to have a history. There are benches in the middle of the forest that must have once had a view, but now only see a row of trees. I didn't test this swing.
