The springs at Glyki are icy and clear, and people wade upstream through the gorge.

What the day actually is

Not a viewpoint. You get into the water.

The wading upstream through the gorge is the activity, and the temperature is the thing everyone mentions afterwards - icy is our own guide’s word, and it is meant literally. Spring-fed water in a shaded gorge does not warm up in August.

We give no route, distance or depth. Our own pages give none, and a river is not a fixed thing: it changes with the season and the rainfall. Look at it on the day and take local advice rather than a page written months earlier - nothing here certifies that any stretch is safe or passable for you.

The Nekromanteion

The Nekromanteion, the ancient oracle of the dead, sits near the Acheron mouth.

That is the other half of the mythology made physical: a river taken for the boundary of the underworld, and an oracle built where it meets the sea to consult the dead. Whether the site functioned as the ancient sources describe is a question our pages do not settle, and neither does this one.

Why Parga is a base

Parga is a base as much as a destination, and the trips are genuinely good. Our guide gives it three nights, which covers a Paxos day, an Acheron day and the town.

The other trip is Paxos and Antipaxos, a day by boat, for the blue caves and the water.

The town you come back to

Parga is a tiered amphitheatre of pastel houses under a Venetian castle on the Epirus coast, looking and feeling like an Ionian island town without being on an island - because it was governed with the Ionian islands rather than the mainland, under Venetian and then briefly British rule, and it was built in that idiom.

The castle walk is short, free and the best thing in the town.

Practical notes

Getting there: the nearest airport is Preveza, about an hour south. Corfu is also close by ferry and road via Igoumenitsa.

Boat trips are seasonal, which our own guide flags - and the Acheron day is the one that does not depend on a boat.

Common questions
