Location

It is the only coastal town in the five making up the valley; it is bounded by Amoroto, Berriatu and Lekeitio. The centre of Mendexa, though, is not by the sea but in the interior, at the top of a hill. It has been there since it was built in the Middle Ages. The town is divided into four neighbourhoods: Iturreta, Leagi, Likona and Zelaia. Some are in the seaside, and some at a hilltop. The town has a total area of 6,69 Km².

There are few people living in Mendexa. Nevertheless, according to the last Census, the population has grown in the last few years; this is because some inhabitants of Lekeitio could not afford to buy a house there and moved to Mendexa. The town has magnificent views: the sea and the hills meet in this area. The only beach in the Lea Valley, Karraspio, is also there.
