The town
Agrinio grew on tobacco. For much of the twentieth century this was the processing centre of Greek tobacco, and the large warehouses of the Papastratos company still stand, some restored into cultural and municipal buildings.
The modern town is functional: a long pedestrian main street, squares, a park, and the ordinary business of a farming and commercial centre. It is not a sight and does not pretend to be.
Lake Trichonida
The lake is the reason to detour. It is large, deep and ringed by hills, with small villages around its shore, and it is almost entirely undeveloped for tourism.
The southern shore road, from Thermo back towards Agrinio, is the good drive: olive groves, water on one side, hills on the other, and almost no traffic.
Thermo itself, at the eastern end, holds the sanctuary of Apollo Thermios, the federal centre of the Aetolian League, with a long narrow temple, stoas and a museum. It is a significant site with very few visitors.
Ancient Stratos
North of Agrinio on the Acheloos river stands Stratos, one of the largest fortified circuits in Greece: several kilometres of ancient city walls with towers, and a temple of Zeus, spread over hills above the river. It is unfenced, unstaffed and mostly empty.
Where it fits
- Messolonghi and its lagoon, about forty minutes south.
- Nafpaktos, an hour south-east.
- Ioannina, about two hours north on the Ionian motorway.
Agrinio is a stop on the way between them rather than a destination.
Getting there and how long
On the Ionian motorway between Antirrio and Ioannina, about three and a half hours from Athens.
One night, using it for the lake and Thermo.
