With the weather warming up, many people are looking for a slice of Greek paradise. While crowds flock to popular spots such as Santorini and Mykonos, another breathtaking town is still flying under the radar.

Nafplio, a charming seaside spot in the Peloponnese, is being hailed as Greece’s best-kept secret. With its stunning views, cobbled streets and romantic harbour, it offers all the beauty of the Greek islands – minus the sky-high prices and packed-out promenades.

Once the capital of modern Greece, this elegant city is winning over travellers looking for something a little more laid-back.

And according to delighted visitors on TripAdvisor, that’s exactly what makes it so special. “Absolutely magical,” writes one five-star reviewer. “We visited in July and it felt like we had the place to ourselves.”

Another added: “It’s Greece at its most romantic. The sunsets, the food, the charm, it’s like something from a movie.”

Just two hours’ drive from Athens, Nafplio offers a heady mix of Venetian architecture, neoclassical mansions, flower-filled balconies and winding alleys packed with boutique shops and traditional tavernas.

Towering above the city is the Palamidi Fortress, a spectacular 18th-century stronghold reached by 999 stone steps.

From the top, visitors are rewarded with sweeping views over the sparkling Argolic Gulf, the red-tiled rooftops below, and the surrounding hillsides dotted with olive trees.

Out in the harbour lies Bourtzi, a small fortress-island that once guarded the city from invaders. Today, it’s a favourite for boat trips and photo ops.

But it’s not just the sights that have visitors hooked. The atmosphere in Nafplio is delightfully unhurried.

There's no elbowing for a sunset photo, no packed beach bars pumping out music until dawn, just the quiet clink of cutlery at dinner, the occasional church bell, and the gentle hum of Greek conversation wafting through the streets.

For beach lovers, Arvanitia Beach is just a short stroll from the old town, offering calm, clear waters ideal for a cooling dip. A little further afield lies Karathona Beach, a long stretch of sandy shore surrounded by nature, with space even in the height of summer.

Nafplio is quickly gaining a reputation as Greece’s best-kept secret, thanks to its unique blend of culture, seaside beauty and genuine warmth. Yet despite the rising interest, it has managed to avoid the overdevelopment seen in more famous destinations.

And for many visitors, that’s what makes it feel truly special. “I didn’t hear a single hen party or nightclub until 3am, just the sound of waves and locals enjoying life,” said one British holidaymaker. “It’s like Greece before it got overrun.”

So if you’re looking to swap the stress of Santorini for somewhere just as stunning but with a whole lot more space to breathe, Nafplio might just be your dream destination. But if you go, just don’t be surprised if you end up wanting to keep it all to yourself.
