Aia-Orio is a railway station in Aia, Basque Country, Spain; serving primarily the town of Orio. It is owned by Euskal Trenbide Sarea and operated by Euskotren. It lies on the Bilbao-San Sebastián line.

Orio is a fishing town located in the province of Gipuzkoa in the Basque Autonomous Community, northern Spain, with the town nucleus lying on the river Oria, roughly one mile away from its mouth by the Bay of Biscay. Orio had a population of 5,901 inhabitants as of 2016. Traditionally a town attached to the sea and the fishing industry, this sector is losing ground to the more profitable and less demanding tourism, rapidly developing after marshes between the town and the beach were drained with a view to building up new tourist oriented housing. The most widely known and conspicuous sport activity in Orio is the rowing regatta typical of the Basque and Cantabric coastal area, featuring a team represented by the yellow colour. The town is served by Euskotren Trena's coastal line, the N-634 road and the A-8 motorway (since 2010). A festival representing the last catch of North Atlantic right whales within Basque whaling in 1901, have been held on every 5 years. This catch also reflected in a folk poem popularized by singer-songwriter Benito Lertxundi.

The Oria [ˈoɾja] is a river in the Basque Country at the north of the Iberian Peninsula. It's one of a series of Basque rivers flowing into the Bay of Biscay (Atlantic basin) and the main river of the province Gipuzkoa in volume (25.6 m3/s), length (75 km) and basin (882.5 km2), the main feature of these rivers aligned south to north being their shortness. The maximum elevation at the source is 1,260 m, while at its lowest height the tidal influence extends inland up to Usurbil (estuary). On this final stretch, many marsh and wetland strips dotted the banks of the Oria, although some of them have been drained for agricultural and building purposes. The river rises at the south of the municipality of Zegama near the hamlet of Otzaurte and the San Adrian tunnel, harvesting the waters of the north-eastern side of the mountain range Aizkorri, so the river results from the merging of several streams. The first town it crosses is the very nucleus of Zegama, with other major towns of Gipuzkoa being located on the river, e.g. Beasain, Ordizia, Tolosa, Andoain, Lasarte-Oria, Usurbil and finally Orio at the mouth. From Lasarte-Oria to Orio, the sinuous and traffic laden coastal road N-634 winds along. The Oria is a central river and an important axis for the province of Gipuzkoa. The major road A-1 (European route E-5 E-80) runs along the Oria most of the time, as well as the Spanish Northern Railway, right from its rise on the slopes of Aizkorri. Its watershed holds a population of 128,000 inhabitants, most of the lowland being heavily inhabited, while the area of its southernmost stretch is sparsely populated.

The Agorregi Forge is located within the Pagoeta Nature Reserve, near the town of Aia, in the Basque Province of Gipuzkoa, Spain. It is one of the best preserved examples of a foundry in Gipuzkoa province. The forge which can be seen today is a built in 1754 by the lord of Laurgain Palace over the ruins of an earlier version. Lying at the bottom of a deep valley near Manterola farmhouse, it used the river's hydraulic energy to power its great bellows and turn its waterwheels.
