Things to Do in Kastos: Beaches, Caves & a Tiny Ionian Village
Kastos is one of the smallest inhabited islands in the Ionian Sea and one of those places where doing less is really the point.
The island lies south of Kalamos and opposite the mainland coast near Mytikas. It has just one settlement, Kastos village, and the Municipality of Lefkada describes it as the smallest inhabited island of the Ionian Islands.
There are no major archaeological complexes, resort towns or long lists of organised attractions here.
Instead, Kastos is about swimming in clear Ionian water, walking along quiet roads and paths, exploring the little harbour, finding old windmills and olive presses, and slowing down to the pace of a tiny Greek island.
Here are the best things to do in Kastos.
1. Explore Kastos Village
Best for: getting your bearings
Kastos has only one village, located around a sheltered bay on the island’s eastern coast.
This is the centre of life on the island.
Small houses climb gently away from the waterfront, while fishing boats and visiting yachts gather around the harbour during summer.
Don’t arrive expecting a long checklist of sights.
Walk through the village, explore the waterfront, stop for a coffee or meal and enjoy the absence of traffic and crowds.
Kastos is small enough that the village quickly begins to feel familiar.
2. Walk to the Old Windmill
One of Kastos’s most distinctive landmarks is its old windmill above the village.
The Regional Unit of Lefkada notes that the windmill’s mechanism is still preserved, while historical accounts describe it as one of the best-preserved traditional windmills in the Ionian Islands.
The walk also gives you a reason to leave the waterfront and see Kastos from a different perspective.
From higher ground, the combination of olive trees, blue sea and neighbouring islands gives you a better appreciation of just how small and isolated Kastos really is.
3. See the Old Olive Presses
Olive growing has long been part of life on Kastos.
Remnants of old olive presses survive on the island and provide a glimpse of an era when the small population relied much more heavily on local agriculture.
You don’t need to treat them like major museum exhibits.
They’re part of the historic landscape you encounter while walking around Kastos, alongside old stone buildings, olive groves and the windmill. The regional tourism authority specifically identifies old oil presses among the features visitors can discover on the island.
4. Visit Agios Ioannis Church
The main church in Kastos village is Agios Ioannis Prodromos.
The church contains large religious paintings by the Ionian painter Spyridon Gazis. Beneath it is a vaulted stone structure believed to be associated with an early Christian tomb.
The feast of Agios Ioannis is celebrated on 23–24 June, making this a particularly interesting time to experience the island if your visit happens to coincide with it.
Even outside the festival, the church is one of the few historic sights within the settlement and is worth looking for while exploring the village.
5. Discover Fokotrypa Cave
Best for: Kastos’s most unusual natural attraction
One place that genuinely stands out on Kastos is Fokotrypa Cave.
The cave lies north of the main settlement and extends around 30 metres into the coastline. Most unusually, it contains a small sandy beach inside the cave.
Visit Greece also highlights Fokotrypa as one of Kastos’s notable attractions and describes the little beach inside as accessible from the water.
Its name is associated with seals — fokia in Greek — reflecting the marine character of this part of the island.
This is one place where exploring Kastos from the sea really pays off.
6. Swim at Kastos’s Beaches
Kastos may be tiny, but its coastline contains a surprising number of small beaches and coves.
The Municipality of Lefkada specifically describes the island as green and peaceful with beautiful beaches, while the regional tourism authority highlights swimming as one of the main reasons to visit.
Don’t expect large organised beaches.
The appeal is finding small stretches of shoreline with clear Ionian water and relatively few people.
We’ll cover the individual beaches properly in our separate Best Beaches in Kastos guide.
7. Go Snorkelling
Kastos’s clear water and rocky shoreline make it a natural place to take a mask and snorkel.
You don’t need a dedicated snorkelling excursion.
Simply take your equipment when visiting the beaches and coves and explore wherever conditions are suitable.
Fokotrypa is particularly interesting from the water, but even the more accessible swimming spots around the island provide opportunities to see beneath the surface.
8. Walk to Agios Aimilianos
About four kilometres from Kastos village is the small chapel of Agios Aimilianos.
The chapel stands near the ruins of stone houses associated with an earlier settlement on the island. Nearby is the old olive grove of Kalikerimio.
The walk is worthwhile because it combines several things that make Kastos interesting:
quiet countryside, old stone remains, olive trees, coastal scenery and almost complete absence of development.
Take water and avoid setting out during the hottest part of a summer afternoon.
9. Walk the Island
Best for: experiencing Kastos properly
Kastos is only around seven kilometres long and less than a kilometre wide for much of its length.
That makes walking one of the best ways to experience it.
The Regional Unit of Lefkada specifically recommends long walks among the stone houses, olive groves, old presses and windmill.
There isn’t a need to rush from “attraction” to “attraction.”
Walk until you find an interesting view.
Stop at a beach.
Return to the village for lunch.
That’s a much more appropriate Kastos itinerary.
10. Explore Kastos by Boat
Kastos becomes even more interesting when viewed from the water.
A boat allows you to explore small coves, beaches and sections of coastline that aren’t as convenient to reach on foot.
It also puts Kastos into its geographical context.
Neighbouring Kalamos lies only about a mile away, while Meganisi and other islands and islets form part of the wider Ionian landscape.
Kastos is particularly popular with sailing boats because of its sheltered location and small harbour.
Even if you arrive by passenger boat rather than yacht, getting back onto the water during your stay is worthwhile.
11. Visit Sarakiniko Bay
On the western side of Kastos is Sarakiniko, a sheltered bay used for boat mooring.
It’s very different from the village harbour on the east coast.
The journey across the narrow island gives you another excuse to explore on foot and see the quieter western side.
For sailors, Sarakiniko is particularly useful as an anchorage; for land-based visitors, it’s another example of the small bays and natural harbours that shape life around Kastos.
12. Watch the Boats in Kastos Harbour
This sounds almost too simple to include as an attraction.
On Kastos, it isn’t.
Summer brings yachts and sailing boats into the harbour, creating much of the island’s seasonal activity. The permanent population is tiny, so visiting sailors and returning island families noticeably change the atmosphere during the warmer months.
Find somewhere along the waterfront, order a drink and watch the boats arrive.
On a larger island this might feel like doing nothing.
On Kastos, it’s part of the experience.
13. Have a Long Lunch by the Harbour
Kastos has only a handful of places to eat, which is exactly what you should expect from an island this small.
There are nevertheless genuine restaurants in the village, so there’s no need for the old version of this site to send readers to Argostoli or invent dining options elsewhere.
TAVERNA BELOS and Il Porto Taverna are among the established choices in Kastos itself, while Windmill Taverna provides another option.
We’ll cover them properly in Best Places to Eat in Kastos.
For this page, the important point is simpler: allow time for a leisurely meal rather than treating lunch as an interruption to sightseeing.
14. Enjoy Kastos After the Day-Trippers Leave
If you can stay overnight, Kastos changes character once excursion visitors and boats begin moving on.
The harbour becomes quieter and the island’s small scale becomes much more apparent.
This is one reason I’d distinguish between visiting Kastos and actually staying on Kastos.
A day trip lets you see the village, swim and have lunch.
An overnight stay lets you experience the tranquillity that is really the island’s strongest attraction.
How Long Do You Need in Kastos?
Kastos works perfectly well as a day trip, particularly if you’re travelling from nearby Kalamos or the mainland.
But if slow travel appeals to you, I’d consider two or three nights.
That gives you time to:
explore the village, walk around the island, visit several beaches, see Fokotrypa from the water, enjoy an unhurried dinner and experience the island after most daytime visitors have gone.
You don’t need a week-long sightseeing itinerary.
The attraction is having nowhere you urgently need to be.
Do You Need a Car in Kastos?
No.
Kastos is exactly the sort of island where bringing a car makes little sense for the average visitor.
The island is small, the settlement is compact and walking is part of the experience.
Good shoes are much more useful.
How Do You Get to Kastos?
Kastos has boat connections with the mainland around Mytikas, and neighbouring Kalamos is also closely connected with the island. The Municipality of Lefkada identifies Mytikas as the mainland connection for both Kastos and Kalamos.
Services can vary by season, so don’t build a trip around an old timetable found online.
Check the current boat arrangements for your actual travel dates.
Private boats and sailing itineraries are another common way of reaching Kastos.
Is Kastos Worth Visiting?
Yes — but you need to want what Kastos offers.
Don’t come looking for nightlife, archaeological museums, luxury shopping or dozens of attractions.
Come for:
clear water, small beaches, walking, olive groves, the windmill, Fokotrypa Cave, a tiny harbour village and the chance to spend time somewhere that still feels genuinely small.
Kastos is particularly appealing as part of a slower journey through the lesser-known Ionian islands.
Kastos or Kalamos?
You don’t necessarily need to choose.
The islands lie very close together and complement each other well.
Kalamos is larger and more mountainous.
Kastos is smaller, gentler and easier to comprehend on foot.
If your itinerary allows it, visiting both gives you a much better feel for this quieter corner of the Ionian Sea.
Final Thoughts
The best things to do in Kastos aren’t really about ticking off attractions.
Start in Kastos village.
Walk up towards the old windmill.
Visit Agios Ioannis.
Explore the olive groves and old presses.
Walk towards Agios Aimilianos.
Swim at a quiet beach.
See Fokotrypa Cave from the water.
Then return to the harbour for a long meal while the sailing boats come and go.
That’s Kastos.
And trying to turn it into anything busier would miss the reason for visiting.
