On the southern edge of Evia Island, where the mainland disappears into the shimmering haze of the Aegean, you’ll find Karystos—a place as sculpted by nature as it is by history. Cradled by a dramatic horseshoe-shaped bay and dwarfed by the rugged slopes of Mount Ochi, Karystos commands the entrance of the South Euboic Gulf like a sentinel. This is not the lush, olive-laden Evia of the north; here, the landscape is wild, dry, and battered by the meltemi winds—yet remarkably beautiful.
Karystos is both the political and commercial heart of South Evia and a town that still grows and pulses with life. Since ancient times, it’s been known for its quarries and the coveted Karystian stone slabs that once paved Roman forums and Byzantine churches across the Mediterranean. Today, it balances its ancient legacy with modern appeal: relaxed waterfront cafes, mountain hikes, Venetian castles, and a deep sense of place that you feel immediately upon arrival. Whether you’re chasing windswept views or historical intrigue, Karystos offers a gritty, genuine charm that lingers.

How to Get to Karystos
Getting to Karystos is relatively straightforward, whether you’re driving the full distance or taking advantage of the more relaxed ferry route. If you’re coming from Chalkida, expect a roughly 120-kilometer drive that takes about two hours. The route winds through central Evia, offering changing landscapes but also plenty of twists and turns—especially as you get closer to the south.
The faster and more scenic option from Athens is the ferry from Rafina to Marmari. Ferries usually run three times a day, and the trip takes just over an hour. Tickets cost around €12 per person and €30 for a car. You can purchase tickets at the port or book them online here. Once you arrive in Marmari, it’s only a 15-minute drive east to Karystos along a scenic road with panoramic sea views.
If you’re thinking of doing Karystos as a day trip from Athens, it’s absolutely doable. Take the first ferry out in the morning and catch the last one back in the evening—something I’ve done several times during my private tours to the Dragon Houses of Mount Ochi. It’s a full day, but well worth it.

What to Do in Karystos
Karystos may seem like a sleepy seaside town at first glance, but it reveals layers of culture, history, and natural charm if you give it time. Here’s what to explore once you’re there, starting with sights within the town:
Coastal Promenade and Fishing Port
A walk along Karystos’s stone-paved seafront is a delight in any season. The promenade lines the harbor like a stage set, complete with colorful fishing boats bobbing lazily and the occasional fisherman mending nets on the quay. You’ll pass a string of cafés and seafood taverns, perfect for a slow ouzo or a freshly grilled octopus. The air smells of salt and summer—even in spring—and the pace is as languid as the waves.
Bourtzi Castle
On the eastern edge of the prom, the Bourtzi Castle rises like a stone outcrop from the past. Built by the Venetians in 1350, this two-story, hexagonal horseshoe-shaped tower was constructed using marbles repurposed from a nearby Roman mausoleum. Unlike many fortifications that fell into ruin, Bourtzi is in great condition and frequently hosts summer exhibitions and cultural events. Its compact size makes it easy to visit, but it leaves a strong impression with its elegant, geometric silhouette against the sea. (location)
Archaeological Museum
Housed in the west wing of the Giokaleio Cultural Foundation on Maximilianou Square, across the street from Bourtzi, the Archaeological Museum of Karystos is modest but rich in context. It showcases classical to Roman-era sculpture from the region, inscriptions, and clay figurines from various sites in southern Evia. Particularly noteworthy are the artifacts recovered from the Dragon Houses of Mount Ochi—mysterious ancient stone structures that continue to puzzle archaeologists. The museum occasionally offers guided tours through the local archaeological authority, so it’s worth checking in advance. Admission costs €5. This is its website (Greek only). (location)
Folklore Museum
Karystos’s Folklore Museum is a trip back into 19th-century life, housed in the old mansion of the Moschonás family. It holds the personal collection of Harílis Deliyiórgis, who meticulously recreated the interior of a traditional Karystian home. From weaving tools to wedding garments, the museum doesn’t just display objects—it restores an atmosphere. It’s an intimate and unexpected gem, especially if you’re drawn to ethnography and everyday history.
City Hall and Neoclassical Architecture
Climb up to the central square, and you’ll find the town’s City Hall (location), an impressive neoclassical building crafted from Karystos’s signature marble and the renowned Karystian slate. Built in the 19th century, it anchors the higher part of town with a certain gravitas. Around it, several other neoclassical structures survive, tucked into side streets and revealing the town’s urban aspirations during Greece’s early statehood. Drop down to Amalia Square for a more playful vibe—sea views, thick mulberry trees, and the hum of a town going about its business.
Procurator’s Mausoleum
On the archaeological fringe of Karystos lies the imposing Roman Mausoleum, believed to have belonged to a procurator overseeing the local quarries. Initially misidentified as a temple, this nearly square building features ionic columns made from high-quality cipollino marble—an export for which Karystos was once famous. Measuring over 13 meters per side and dating to the 2nd century AD, it’s a monument of striking elegance. The pediment’s circular medallion (imago clipeata) showing the deceased with his horse adds a personal, almost cinematic detail to this grand tomb. (location)
Church of Saint Nicholas
In a town full of stone and history, the main church of Saint Nicholas adds a burst of serene Cycladic charm. Whitewashed walls, sky-blue domes, and clean architectural lines make it stand out in the town center. Saint Nicholas, the patron saint of sailors, seems fittingly honored in a place so bound to the sea. Step inside for a moment of quiet and admire the iconostasis and flickering candlelight that bring the church to life. (location)
The area around Karystos is packed with cultural landmarks, natural wonders, and enough mystery to keep you wandering for days. Here’s what to look for just outside town:
Castello Rosso (Red Castle)
About 4 kilometers inland, between the villages of Grabias and Myloi, the Castello Rosso dominates the foothills of Mount Ochi. Built with its namesake red stone, this medieval fortress offers cinematic views over Karystos Bay, especially at sunset. Though in ruins, the towering battlements and arched doorways still evoke the feudal lords who once ruled South Evia from here. The short hike up adds to the adventure and rewards you with one of the best panoramic vistas in the region. (location)
Beaches
Karystos’s bay stretches over 20 kilometers, offering a mix of organized and wild beaches. For convenience, Psili Ammos, West Beach, Bouros-Agalma, and Agia Paraskevi come with umbrellas and facilities. If you’re after solitude, you can head to unorganized spots like Kastri or take a sea taxi (call Tasos Roussis at +30 6936907170) to reach remoter gems along the Cavodoro coastline. The combination of clear waters, sandy shores, and minimal crowds makes beach-hopping here feel like a personal secret.
Dragon Houses of Mount Ochi
One of the great enigmas of Greek archaeology lies just north of Karystos: the Dragon Houses—megalithic buildings dating back to between the 5th and 1st centuries BCE. Constructed with massive unmortared stone blocks, these structures still defy full explanation. The most famous one crowns Mount Ochi, reachable by trail and well worth the climb. Theories range from ancient temples to defensive shelters, but the atmosphere up there—wild, windy, and eerie—needs no interpretation.

Ancient Marble Quarries
High on the slopes of Mount Ochi, around the villages of Mekounida and Aetos, lie the ancient marble quarries. Roman-era masons carved huge monolithic columns directly from the rock here—some up to 12 meters long—and exported the distinctive green-veined Karystian cipollino marble all the way to Rome. You’ll find abandoned columns half-carved and still embedded in the rock, giving you a raw sense of ancient industry amidst wild landscapes. It is mind-boggling to imagine how on earth those guys (poor slaves) transported them down mountains and across seas. (location)
Trails of Mount Ochi
Beyond its archaeological riches, Mount Ochi is a hiker’s dream. Numerous trails crisscross its slopes, leading through such highlights as Ochi’s chestnut forest, the waterfalls of Platanistos and Kapsouriou, and the dramatic Dimosaris Gorge down to the remote beach of Kallianos, where you can take a dip with barely another soul in sight. Whether you’re walking for the views, the flora, or the silence, the mountain will reward your effort.
Wine Tasting at Montofoli Estate
Wine has long been part of Karystos’s story, and the Montofoli Wine Estate lets you sip your way into that history. Nestled among olive trees and ruins, the estate offers guided tastings paired with tales of the land’s ancient and modern use. If you’re visiting in late August, don’t miss the Karystos Wine Festival, where locals celebrate the grape harvest with traditional food, grape pressing, and copious wine in the town square. (location)
Monastery of Saint Mavra
Perched on a hill above Myloi village, the Monastery of Aghia Mavra gazes across the bay and toward the looming Castello Rosso. Though no nuns have lived there for decades, its old calendar traditions and commanding position make it a quiet and spiritual stop. Services still take place on occasion, particularly on its feast day, May 14th. (location)
Byzantine Church of the Taxiarches in Kalyvia
Just 3.5 km from Karystos, in the green hills of Kalyvia, stands the 12th-century Church of the Archangels (Taxiarches)—one of the most significant religious monuments in Karystia. This domed Byzantine temple features layered architecture, with a second chapel dedicated to Saint Nicholas inside. Though it has faced wear over time, the structure is rich with intricate carvings and preserved frescoes. Restoration efforts are ongoing, but the aura of sacred antiquity remains intact. (location)
The Twin Churches & Medieval Tower of Chartzani
In the hills above Karystos, the quiet hamlet of Chartzani hides a trio of historical remnants: two small Byzantine churches—Agios Georgios and Agios Dimitrios—and the ruins of a medieval tower nearby. The chapels, likely from the 14th or 15th century, sit side by side amid olive groves, their worn stone walls and faded interior frescoes offering a glimpse into the area’s monastic past. Near them, the crumbling Frankish-era tower emerges from the overgrowth, once part of a coastal defense network. Remote and unmarked, the site feels like a forgotten page of South Evia’s layered history. (location)
Where to Eat in Karystos
Karystos may be compact, but it’s full of flavor—especially if you know where to look. From hearty Greek classics to burgers and cocktails by the sea, here are a few local favorites worth your appetite:
- Kiouki’s Tavern—Just a few steps from the waterfront, Kiouki’s offers a laid-back, family-run atmosphere with classic Greek meze and grilled meats. Their outdoor seating is ideal for a breezy evening meal, and the grilled octopus or slow-cooked lamb might just have you lingering longer than expected.
- Goniako (Ouzo, Mezes, Grill)—A vibrant taverna specializing in traditional mezes, grilled seafood, and ouzo. Located right on the harbor, it offers a lively atmosphere ideal for enjoying shared plates and drinks with a view of the fishing boats. Perfect for an authentic evening of Greek flavors and convivial ambiance.
- Mr. Jay’s Steak & Burger—If you’re in the mood for something less traditional, this modern spot near the harbor serves solid steak and burgers, with generous portions and a chill vibe. It’s a local favorite for casual dining, especially among younger crowds.
- Naftilos Coffee Bar—This stylish spot offers great sea views, creative cocktails, and a modern lounge feel. It’s ideal for a sunset drink or a relaxed night out, especially during summer weekends when it picks up with a fun, easygoing crowd.
History of Karystos
Ancient Beginnings
Karystos’s history stretches back to the Late Stone Age, with traces of early settlement found in the cave of the Holy Trinity. Myth attributes its founding to the Dropes from Parnassus, later overtaken by the Avantes, a pre-Hellenic tribe. The town appears in Homer’s Iliad, in the Catalogue of Ships, and is recorded in Linear B tablets as “ka-ru-to”—a rare continuity of name across millennia.
Persian Wars and Classical Era
In 490 BCE, Karystos faced a brutal siege by Persian Admiral Datis, who arrived with 200 triremes and 80,000 troops. The town resisted, but eventually capitulated and was looted. Later, it was brought into the First Athenian Alliance by General Kimon and became a member of the Second Alliance. Uniquely, Karystos never rebelled against Athenian dominance, maintaining stable ties with the Delian League. It also participated in the Evian Council during the Macedonian period.
Roman Period and Marble Legacy
Karystos rose to prominence under Roman rule thanks to its green-veined cipollino marble, quarried from the slopes of Mount Ochi. This marble became a luxury export used in monumental Roman architecture. Columns from Karystos still stand in Hadrian’s Library in Athens and the Roman Agora in Rome—testaments to the town’s industrial prowess. It’s frankly mind-boggling to imagine how on earth those guys (poor slaves) transported them down mountains and across seas.
Byzantine and Medieval Fortresses
Strategically important, Karystos was fortified early in the Byzantine era. The area where Castello Rosso now stands was first enclosed in 1030. When the Franks arrived, Karystos became a feudal province, and Castello Rosso was rebuilt by Lombard baron Ravano dalle Carceri between 1209 and 1216. Control of the fortress passed through Byzantine, Frankish, Catalan, and Venetian hands before being captured by the Ottomans in 1470.
The Revolution of 1821
Karystos played a volatile role in Greece’s War of Independence. Supplies for Peloponnesian and Cretan fortresses passed through here in the early months of the uprising. Although Evia revolted in May 1821, Turkish forces retreated to their strongholds in Karystos and Chalkida. Sporadic battles followed—including a failed siege by Odysseas Androutsos in 1822 and multiple offensives led by Nikolaos Kriezotis through 1823.
Despite temporary victories, the Ottomans maintained a grip on Karystos. In 1824, Albanian mercenaries and Janissaries were deployed to secure it. The final siege in 1826, led by General Fabvier, failed after 24 days. A chilling Ottoman document from this time ordered the dispatch of rebels’ severed heads and ears as proof of defeat.
Karystos was eventually handed over to the nascent Greek state in 1829, following diplomatic negotiations with the retreating Ottomans, who demanded compensation for lands they had largely seized without right.
Modern Era
In the post-independence years, Karystos grew modestly, with its distinctive slate—Plaka Karystou—becoming one of the town’s most iconic exports. A darker episode came in 1976 when the Greek government, under Konstantinos Karamanlis, shortlisted Karystos as the site for the country’s first nuclear power plant—an idea originally signed off during the junta years. A fierce local backlash derailed the plan, and by 1982, the government officially scrapped the project.
Karystos today carries these centuries like sediment—layered, weathered, but enduring.
