Ona is a set of two small islands separated by a few metres and a population of 16 registered in 2018. The lighthouse was built in 1867. Ona has been a fishing place in the past. There is a small summer café and two pottery workshops.
The view from the lighthouse is very nice. There is a long white sand beach on the island of Husøya.
There is a connexion from More through bus and ferry.
