Crete’s only lake, in the hills behind Georgioupoli
Crete is an island of 8,336 km² defined by its coastline and its mountains, from the snow-holding peaks of the Lefka Ori to the beaches of the Libyan Sea. What it does not have, almost anywhere, is standing fresh water. That is what makes Lake Kournas worth the detour: a small, roughly circular lake sitting in a limestone bowl in the hills above Georgioupoli, the only naturally occurring freshwater lake on the island. There are reservoirs elsewhere in Crete, built for irrigation, and there are seasonal pools that dry out by summer, but Kournas is the real thing: spring-fed, present all year, ringed by low hills rather than sand.
The lake sits in the Apokoronas region, the gentler, greener country inland from the resort strip between Georgioupoli and Kalyves, on the Chania side of the island. It is not on the way to anywhere dramatic — no gorge mouth, no ruin, no fortress — and that is more or less the point. Visitors come for a change of register: still water instead of surf, plane trees instead of sunbeds, a walking loop instead of a beach towel.
What Lake Kournas actually looks like
Set expectations correctly before you go. This is not a rival to Elafonissi or Balos — there is no sand at all, let alone pink sand, and no turquoise shallows over a lagoon floor. It is also not a volcanic feature; Crete itself has no caldera or thermal spring in the way some other Greek islands do, and Kournas is simple limestone hydrology, not geothermal activity. What you get instead is a genuinely different kind of Cretan scenery: a body of still, green-blue freshwater a few hundred metres across, held in a natural amphitheatre of hills, with reeds and a scatter of plane and eucalyptus trees along parts of the shore.
The water level shifts with the season and with rainfall from one year to the next, so the width of the walkable shoreline in April can look noticeably different from the same spot in September. A path circles the lake, partly shaded, partly open, and takes most people 30-45 minutes to walk at an easy pace. A handful of tavernas cluster near the main access point, serving the kind of straightforward Cretan food — grilled meat, horta, a village salad — that suits a lakeside lunch better than a beachfront one.
Locals and visiting Cretans use the lake too, especially at weekends, which gives it a slightly different feel from the more tourist-facing stops on the coast a few kilometres away. Pedal boats and rowing boats can be hired from operators by the shore. What you will not find, deliberately, is a jet-ski or motorboat concession: Kournas is a protected wetland, and motorised watercraft are not part of what is on offer here, unlike the coastal boat trips out to Dia island or along the Akrotiri coves. If a powered day on the water is what you are after, that belongs on the coast, not here.
Argyroupoli: the springs and plane trees a short drive away
Most people who make the trip to Kournas pair it with Argyroupoli, a village about 10 km away built partly over the ruins of ancient Lappa. Argyroupoli’s draw is water of a different kind: a series of natural springs feeding streams that run down through a grove of enormous plane trees, with small stone bridges, a waterfall, and shaded tavernas built out over the water on wooden platforms. Where Kournas is open and hill-ringed, Argyroupoli is close, cool and green, and the contrast between the two is part of why they are so often visited together as a single half-day loop.
Argyroupoli is also a working village rather than a purpose-built attraction — houses, churches and small shops sit alongside the spring gardens, and Roman-era rock-cut tombs are visible on the approach road, a reminder that this was a settled site long before it became a lunch stop for people heading to or from the lake. The two places share a rhythm: quiet, green, inland, and best enjoyed slowly rather than ticked off quickly.
Getting there: why this is a driving day, not a coach day
Crete has no railway anywhere on the island, and this is one of the clearest places that matters. The KTEL coach network genuinely works along the north coast highway linking Chania, Rethymno and Heraklion, but it thins out fast once you leave that corridor. Lake Kournas and Argyroupoli sit inland, off the main road, connected to each other and to the coast by minor roads that coaches do not reliably run. In practice, almost everyone reaches this pair of sites by rental car, by private tour, or by taxi arranged from a coastal base such as Georgioupoli or Kalyves.
If you already have a rental car for the week, this is an easy half-day addition to a stay on the north coast — see our guides to driving in Crete and renting a car for the practical basics, and note that mountain roads here are narrow with locals pulling onto the shoulder to let faster traffic pass, not an invitation to overtake blind. If you are travelling without a car, check our notes on KTEL buses in Crete before assuming you can reach the lake independently, and consider a guided tour instead, which typically bundles Kournas, Argyroupoli and sometimes a village stop into one organised loop.
A few road-trip pairings work well from the coast:
| Starting point | Distance to Lake Kournas | Typical driving time |
|---|---|---|
| Georgioupoli | About 5 km | 10 minutes |
| Kalyves | About 15 km | 20 minutes |
| Chania | About 45 km | 40 minutes |
| Rethymno | About 24 km | 30 minutes |
From the lake, Argyroupoli is a further 10 km or so along hill roads, and both sites can comfortably be combined with a stop in the village of Therisso or a longer loop toward Anogia for travellers with a full day rather than half a day to spend inland.
When to go
The lake and the springs are open year-round, but the season that suits swimming and lakeside lunches runs May to October, matching the rest of the island’s warm-weather calendar. Within that window, late April through June is the most rewarding stretch for scenery: the surrounding hills are still green from the winter and spring rains, wildflowers are out, temperatures are comfortable for walking the lake path, and the crowds are noticeably thinner than in high summer.
By July and August, the hills have dried to their familiar summer gold-brown and the heat can make the shaded plane trees of Argyroupoli genuinely more comfortable than the open shoreline at Kournas. September brings back some of the greenery-adjacent comfort of spring, with warm water and fewer visitors than August. See our month-by-month notes in when to visit Crete and Crete in May for more detail on how the shoulder seasons compare.
Outside the May-October window, both sites stay accessible — Argyroupoli’s tavernas and springs are a pleasant stop even in a Cretan winter, and the lake itself never closes — but swimming stops being realistic and some of the lakeside food operators reduce their hours or close for the season, in line with how much of rural inland Crete quietens down between November and March.
What to actually do there
A visit to Lake Kournas and Argyroupoli is built around slow, low-key activities rather than a single headline sight:
- Walk the lake loop. The full circuit takes 30-45 minutes and passes through open shoreline, patches of shade, and a few small tavernas and boat-hire points.
- Swim. The water is genuinely swimmable from late spring through early autumn, cooler than the sea and with a soft, sometimes muddy lake bed rather than sand.
- Hire a pedal or rowing boat. This is the one water activity on offer, deliberately non-motorised, and a good option for families with children.
- Eat lakeside or streamside. Tavernas at Kournas serve straightforward grills and mezze with a lake view; at Argyroupoli several restaurants are built directly over the spring water, shaded by plane trees, which is a distinctly different lunch setting from anywhere on the coast.
- Walk the Argyroupoli spring gardens. Paths, small bridges and a waterfall run through the plane grove, with the Roman-era rock tombs visible on the approach into the village.
- Watch for birdlife. The lake supports resident ducks and other waterbirds and is a known stop for migratory species, making it a modest but genuine birdwatching spot for an island better known for its gorges than its wetlands.
What you will not find, and should not expect, is a beach club atmosphere, sunbed rows to the horizon, or any of the powered watersports common on the coast — this is quieter and smaller in scale than that comparison implies.
Combining Lake Kournas with the rest of Apokoronas
Because the lake sits inland from Georgioupoli and Kalyves, it works naturally as a half-day break from a beach-based stay on that stretch of coast, or as one stop on a longer loop into the Apokoronas hills. Travellers based in Chania or Rethymno more often treat it as a half-day excursion by car, sometimes extended to include Argyroupoli, a village lunch, and a return along the coast road. For a broader sense of what oils, wines and produce this part of Crete is known for away from the lake itself, see our guide to olive oil mills and tastings, since several producers in this belt of Apokoronas and neighbouring Rethymno are set up for visits and tastings.
For travellers weighing whether a car is worth the cost and hassle for a trip that also takes in inland stops like this, our guide to Crete without a car for seven days is a useful reality check: routes built entirely on coach and organised transfers can cover the coastal towns well, but sites like Lake Kournas and Argyroupoli are exactly the kind of stop that gets much harder, or impossible, without a car or a tour.
Booking a guided visit
For travellers who would rather not navigate the hill roads themselves, or who want the lake paired efficiently with Argyroupoli and a nearby olive oil producer in one organised day, several tours run from the Chania and Rethymno side of the island.
A small-group option covering both the lake and the village springs is the half-day trip from Chania to Kournas Lake and the Argyroupoli springs, which removes the need to self-drive the connecting hill roads. Travellers who prefer a more flexible, personalised pace can look at the private SUV tour to Lake Kournas and Argyroupoli, which allows extra stops along the way.
For a version that folds in a tasting alongside the lake and springs, the half-day wine tasting and olive oil factory visit near Kournas Lake combines the landscape with a taste of what this part of Apokoronas actually produces.
Practical notes
- No entrance fee for the lake itself; you pay only for boat hire, sunbeds, or food.
- No lifeguard and no marked swimming zone — supervise children closely, and expect a gradually shelving, sometimes muddy lake bed rather than sand.
- Parking clusters near the main taverna strip and fills up on summer weekends when local families visit alongside tourists.
- Shade is limited around the open sections of the lake; Argyroupoli’s plane grove is the better midday option in high summer.
- Combine, don’t rush — most visitors find half a day comfortable for both sites without feeling hurried, longer if lunch is part of the plan.
Lake Kournas and Argyroupoli: your questions answered
Is Lake Kournas really the only lake in Crete?
Yes. Crete has irrigation reservoirs and the occasional winter pool in the mountains, but Lake Kournas is the island’s one naturally occurring freshwater lake, formed in a limestone basin in the hills of Apokoronas with no outlet river.
Can you swim in Lake Kournas?
Yes, swimming is allowed and popular from roughly May to October. There is no sand beach and no lifeguard, the shoreline is reeds, gravel and a few built platforms, and the water is noticeably cooler than the sea.
Is there an entrance fee for Lake Kournas?
No, walking the lake path and swimming are free. You pay only for extras such as a sunbed, a pedal boat rental, or food and drink at one of the lakeside tavernas.
How far is Argyroupoli from Lake Kournas, and how do I get between them?
Argyroupoli is around 10 km from the lake on winding hill roads, roughly 15-20 minutes by car. There is no train on Crete and KTEL coaches do not reliably serve this inland loop, so a rental car is the practical way to link the two sites.
Can I rent a kayak or motorboat on the lake?
Pedal boats and rowing boats are available from operators by the shore, but Lake Kournas is a protected wetland and motorised watercraft are not part of what is on offer here, unlike the powered boat trips available along the coast.
Is Lake Kournas worth visiting without a car?
It is difficult. Public coach coverage in Crete is strongest along the north coast highway between Chania, Rethymno and Heraklion, and thins out quickly inland. Most visitors reach the lake and Argyroupoli by rental car, private tour, or taxi from Georgioupoli or Kalyves.
What is the best time of year to visit Lake Kournas?
May to October covers the swimming season, with July and August the hottest and busiest. Late April through June brings greener hills, wildflowers and cooler days, which many travellers prefer to the heat and crowds of peak summer.
Are there eels or other wildlife in Lake Kournas?
Yes, the lake supports eels, terrapins and a resident population of ducks and other waterbirds, and it is a recognised stop for migratory species. Fishing is not part of the visitor experience here, as the lake’s ecology is protected.
