Around the hotel · Astros
A friendly seaside town on the coast road in northern Kynouria, with a Frankish castle on a hill, a long calm beach and a house where Greek history was made. A good half-day from the hotel, or a stop on the way to Nafplio.
The short answer
Astros is in the Arcadian part of the east coast, with the village a few kilometres inland and a long beach at Paralio Astros on the sea. It is easy to reach, and it makes a pleasant stop between Nafplio and Leonidio.
It has a ruined Frankish castle on a hill, a small archaeological museum beside an elegant old mansion, a Roman villa and a mountain monastery. It is also known for calm, clean water and family beaches.
If you are staying with us, Astros is an easy half-day outing up the coast. This is how we would plan it.

What to see
The castle
A castle on a hill known as the Island, built in 1256 by William II of Villehardouin, Prince of Achaia. The hill is pleasant to walk in the evening, with tiled houses and flowery yards.
The museum
A small museum in the inner village that holds finds from the area, including marble inscriptions and statues from a Roman mansion.
The history
The museum sits next to an impressive neoclassical mansion where the Second National Assembly of the Greek revolution took place in 1823.
The beach
A long beach with calm, clean water in front of the village on the sea, with tavernas and cafés along the front.
The mountain
A well-kept convent about three kilometres up the mountain, built on the ruins of an ancient sanctuary, with a 12th-century church.
Our tip
See the castle and museum in the cool of the morning, swim in the afternoon and eat at the beach in the evening.
Roman remains
Nearby are the remains of a large Roman villa built by Herodes Atticus in the second century, with mosaics, and a stretch of Roman aqueduct with an arch over a stream. They are worth a stop if you like old stones.
Check opening times before you go, as small sites can keep short hours.
Astros and the east coast
Astros sits between Nafplio and Leonidio, so it fits naturally into a trip along the coast. Stop for lunch and a swim, see the castle, then continue south to the red cliffs.
If you are staying with us at Sampatiki, it makes an easy half-day on the way north, or an easy way to begin a trip towards Nafplio.
From us at Sampatiki
Astros is a lovely stop on the way to us. Our reception can suggest a route and a good place for lunch, and we are about an hour further down the coast.
