Argostoli is known for its relaxed Ionian charm, where turquoise waters meet vibrant waterfront promenades and warm island hospitality. As the capital of Kefalonia, Argostoli blends natural wonders with historical intrigue, making it one of the most captivating towns in the Greek islands.
Whether you’re visiting for the day or planning a longer island stay, here are 10 unforgettable experiences that show exactly what Argostoli is known for.
1. Loggerhead Sea Turtles in the Harbor
Few things define Argostoli more than its unexpected wildlife encounters—especially the presence of the endangered loggerhead sea turtles (Caretta-caretta) gliding through its harbor. These gentle giants often appear near the fishing docks early in the morning, drawn to the boats as fishermen sort their catch. Watching the turtles surface for air while the town awakens is a calming, bucket-list moment for nature lovers.
Along the town’s Koutavos Lagoon, the waters are calm and ideal for spotting wildlife. Conservation groups often monitor the turtle population here and local guides offer eco-friendly tours to help visitors understand and protect this delicate ecosystem.
2. Myrtos Beach
Argostoli serves as the perfect base for exploring Kefalonia’s jaw-dropping coastline, including the island’s most iconic beach—Myrtos. Framed by sheer limestone cliffs, this dazzling bay of white pebbles and neon-blue waters is regularly ranked among the best beaches in Europe.
Visitors can take scenic drives from Argostoli to reach Myrtos or join half-day excursions that combine it with other stunning coastal sights. Along the way, expect panoramic viewpoints, hidden coves and picture-perfect villages perched on hillsides. Even a short dip in Myrtos' vibrant waters is enough to leave a lasting impression.
3. The De Bosset Bridge and Koutavos Lagoon
Spanning over 2,500 feet across the Koutavos Lagoon, the De Bosset Bridge is one of Argostoli’s proudest landmarks—and the longest stone bridge over the sea in the world. Built in 1813 during British rule, the bridge connects the main town to the opposite shore and offers spectacular views of the lagoon and distant mountains.
Strolling or cycling across the bridge is a favorite local pastime. The peaceful setting is ideal for spotting turtles, bird-watching or enjoying a moment of solitude surrounded by nature. At sunset, the bridge glows with golden light, making it a popular spot for evening walks and photography.
4. Daily Markets and Fresh Island Flavors
Argostoli’s morning waterfront market buzzes with local life as fishermen unload crates of glistening sardines, squid and mullet. Just steps away, stalls overflow with oranges, olives, fresh herbs and thyme honey harvested in Kefalonia’s hills. It’s a feast for the senses and a window into the island’s agricultural soul.
Beyond the market, the town’s bakeries and grocers tempt with Kefalonian specialties—from feta-stuffed kreatopita (meat pies) to almond sweets like mandoles. Many visitors pick up locally made olive oil or wine to take home, a flavorful reminder of Argostoli’s bounty.
5. The Katavothres Sinkholes and Natural Phenomena
A short drive from the center of Argostoli brings you to one of the island’s most unusual natural sights: Katavothres. Here, seawater disappears into rocky crevices along the shore, traveling through underground limestone channels before re-emerging nearly 10 miles away at the Melissani Cave.
This rare geological phenomenon fascinated 19th-century scientists and still intrigues modern visitors. Today, the site includes a restored watermill and an interpretive display that explains the science behind the subterranean journey. It’s a quiet, off-the-beaten-path stop that shows just how mysterious Kefalonia’s landscape can be.
6. St. Theodore Lighthouse and the Fanari Peninsula
Jutting out into the Ionian Sea, the Fanari Peninsula offers a scenic escape just west of Argostoli. Its centerpiece is the St. Theodore Lighthouse, a small but striking structure built in 1828 with a circular colonnade and a simple lantern tower at the top. The lighthouse was destroyed during the 1953 earthquake but lovingly rebuilt in its original style.
Surrounded by rocky shores and pine trees, it’s a tranquil place to visit, especially in the early evening when the sea turns silvery-blue. The path leading here is lined with coastal cafés and viewpoints, ideal for a relaxed walk or bike ride.
7. The Town’s Vibrant Promenade
Argostoli’s seafront promenade is where the town’s heart beats loudest. Lined with palm trees, traditional lamp posts and open-air cafés, it stretches along the harbor and draws both locals and visitors for coffee breaks, evening strolls and people-watching.
The vibe is especially magical at dusk, when the lights begin to twinkle and the sound of clinking glasses mixes with the lapping waves. Along the promenade, you’ll also find historic monuments, small museums and the local theater, all adding layers to Argostoli’s charm.
8. Venetian-Era Castles and Hilltop Villages
Kefalonia has a rich Venetian heritage and Argostoli is perfectly positioned for exploring some of its best-preserved remnants. Just 15 minutes from the town center, the ruins of Saint George’s Castle (Kastro) sit atop a hill, offering sweeping views of olive groves and distant coastlines.
Once the island’s capital, this medieval fortress features old ramparts, stone gates and traces of former dwellings. The surrounding village is equally atmospheric, with quiet streets, historic churches and cozy tavernas where you can savor traditional dishes like kokkinisto (braised beef in tomato sauce) after a walk through history.
9. Melissani Cave and Underground Wonders
No visit to Argostoli would be complete without a short excursion to Melissani Cave, a natural marvel located about 30 minutes away. This semi-open cavern houses a crystal-clear underground lake that appears to glow blue when sunlight streams through the collapsed roof above.
Visitors board small boats to glide through the surreal scenery, with water so transparent it looks almost invisible. The cave has mythological ties to the nymph Melissanthi and is one of Kefalonia’s most photographed destinations. Combine it with a stop at the nearby Drogarati Cave for a double dose of underground awe.
10. Local Cuisine and Island Hospitality
Argostoli is known not only for its natural beauty but also for its soul-warming cuisine. Tavernas throughout town serve up rich, comforting dishes like pastitsio (Greek lasagna), grilled octopus and hearty meat pies unique to Kefalonia. Robola wine, made from a grape native to the island, is the perfect pairing—dry, floral and distinctly local.
Dining here is about more than food—it’s about connection. Meals unfold slowly, accompanied by conversation, laughter and maybe even live bouzouki music. Whether you’re at a seaside table or tucked into a shady courtyard, the hospitality is genuine and the flavors are unforgettable.
