Ohtakari holds a fishing port, a fishing museum, a Lutheran Evangelical Association of Finland (Suomen Luterilainen Evankeliumiyhdistys ry, SLEY) camp and an old turf maze, or Troy Town. There is also a look-out tower and functioning lighthouse. An annual festival is held in the village.
The oldest taxation records of Ohtakari date to the 1500s. Fishermen lived on the island during the best fishing period. The island also served as a pilot's station for more than a hundred years. The work of the fishermen in the old days is presented in the fishing museum. The causeway leading to the island was completed in the 1970s.
