Whether you’re catching that golden morning light hitting Mykonos’ windmills or diving into the incredible caves of Milos, trust me—these islands will steal your heart. Let me show you my favorite spots.

Best Things to Do in the Greek Islands

Visiting the Greek Islands? Spend the day exploring the stunning Ionian Sea, venture into the Mystical Caves of Milos, or wander the charming streets of Mykonos Town. Stroll through the breathtaking Oia in Santorini for iconic sunset views, embark on a journey through the Ancient Ruins of Delos, or enjoy fresh seafood at a waterfront taverna. Whether you’re into history, outdoor adventures, or coastal charm, the Greek Islands have plenty to offer!

1. Ionian Sea

Sailing the Ionian Sea is a must for exploring Greece’s stunning western islands, from Corfu to Zakynthos and Lefkada. The crystal-clear waters, hidden coves, and dramatic cliffs make every stop unforgettable. Whether you’re island-hopping by yacht or joining a guided boat tour, the Navagio Beach (Shipwreck Beach) in Zakynthos and the sea caves of Paxos are must-sees. Snorkel in Antipaxos’ turquoise waters or relax at a seaside taverna on Meganisi for the freshest seafood and local wine.

I spent a day sailing from Lefkada, stopping at secret beaches only accessible by boat. The best part? Anchoring in a secluded bay for a swim, then enjoying a grilled octopus feast by the water. Whether you’re after adventure or pure relaxation, the Ionian Sea delivers an unforgettable experience. If you love the ocean, this is one journey you won’t want to miss.

2. Mystical Caves of Milos

Milos is home to some of the most stunning sea caves in Greece, best explored by boat. The Kleftiko Caves, once a pirate hideout, feature towering white rock formations and vibrant blue waters perfect for snorkeling. Sykia Cave, with its collapsed roof, creates a sunlit natural pool that feels almost surreal. Kayaking through the Papafragas Caves reveals narrow rock passages and secluded beaches framed by volcanic cliffs. Each cave offers a mix of history, adventure, and jaw-dropping scenery.

I joined a boat tour and swam through Kleftiko’s crystal-clear waters, spotting colorful fish beneath me. The contrast of bright turquoise water against white limestone is unforgettable. Whether you’re snorkeling through underwater caves, marveling at rock formations, or just soaking in the views, Milos offers a side of Greece you won’t find anywhere else. If you’re wondering what to do in the Greek Islands, exploring Milos’ sea caves is a must.

3. Mykonos Town

Mykonos Town is a maze of whitewashed alleys, blue doors, and bougainvillea-lined streets, where every turn reveals a hidden café or boutique. Start at the famous windmills of Kato Mili, then stroll through Little Venice, where colorful balconies hang over the sea. Stop by Matogianni Street for shopping, from handmade jewelry to designer fashion. The town’s beachfront tavernas serve some of the best seafood in Greece, and the small chapels scattered throughout add to its charm.

I got lost in the winding streets and ended up at a rooftop bar with an insane sunset view. At night, the town transforms—Scorpios and Cavo Paradiso bring world-class DJs, while Caprice Bar is perfect for a quieter cocktail by the water. Whether you’re here for beach clubs, boutique shopping, or hidden tavernas, Mykonos Town blends traditional charm with a buzzing social scene.

4. Oia in Santorini

Oia’s sunset is legendary, and for good reason. As the sun dips behind the caldera, the sky turns into a masterpiece of orange, pink, and deep purple. The best views are from Oia Castle, but expect crowds—locals and visitors alike claim their spots hours before sunset. For a more private experience, book a table at Kastro Restaurant and enjoy the view over a glass of Assyrtiko wine. Ammoudi Bay also offers a breathtaking perspective with fewer people.

I watched the sunset from a cliffside terrace, completely mesmerized as the colors reflected over the Aegean Sea. After dark, Oia glows with lantern-lit streets, making it perfect for an evening stroll. Boutique shops, rooftop bars, and romantic tavernas stay open late. If you’re looking for the most magical experience in the Greek Islands, an Oia sunset is something you’ll never forget.

5. Ancient Ruins of Delos

Delos, a short ferry ride from Mykonos, is one of the most important archaeological sites in Greece. According to mythology, it’s the birthplace of Apollo and Artemis, making it a sacred island in ancient times. Wander through the Terrace of the Lions, where marble lion statues stand guard, and explore the remains of grand temples, an ancient amphitheater, and intricate mosaics in the House of Dionysus. The Archaeological Museum of Delos houses artifacts from the island’s golden age.

Walking through Delos felt like stepping back into ancient Greece—a vast, open-air museum with breathtaking ruins. The views from Mount Kynthos, the island’s highest point, are incredible, offering a panoramic look at the surrounding Cycladic islands. If you’re a history lover or just looking for a unique Greek Island experience, Delos is an unforgettable journey into the past.

6. Chania

Chania, on Crete’s northwestern coast, is a blend of Venetian, Ottoman, and Greek influences. The Old Venetian Harbor is a postcard-perfect spot with colorful buildings, a 16th-century lighthouse, and lively waterfront tavernas. Stroll through the narrow streets of the Old Town, where boutique shops, spice markets, and ancient mosques add to the city’s charm. Visit the Archaeological Museum of Chania for a glimpse into Minoan history, or sip raki at a seaside café.

I spent an afternoon wandering Chania’s hidden alleys, discovering local bakeries and handcrafted leather shops. As the sun set, I enjoyed a seafood dinner at Tamam, a restaurant tucked inside an old Turkish bath. The mix of history, culture, and stunning coastal views makes Chania one of the most beautiful places in Crete. Whether you’re here for the food, history, or the laid-back atmosphere, this town will steal your heart.

7. Samaria Gorge

Crete’s Samaria Gorge is a 16-kilometer hiking trail that winds through towering cliffs, ancient forests, and rugged landscapes. It starts at the Omalos Plateau and descends through dramatic rock formations and narrow passages, eventually leading to the Libyan Sea in the coastal village of Agia Roumeli. Along the way, you’ll pass the Iron Gates, the gorge’s narrowest section, where the cliffs rise almost 300 meters high.

The trek took me about six hours, and while it was challenging, the views were absolutely worth it. Wild goats known as kri-kri roam the trails, and fresh mountain springs provide perfect spots to cool off. At the end of the hike, I jumped into the sea before grabbing a cold drink at a beachside taverna. If you love hiking, nature, and epic scenery, Samaria Gorge is an experience you won’t forget.

8. Naxos

Naxos is home to some of the most stunning beaches in Greece, with soft golden sand and crystal-clear waters perfect for swimming. Plaka Beach is a dream—long, uncrowded, and lined with traditional tavernas serving fresh seafood. Agios Prokopios offers turquoise waters and lively beach bars, while Alyko Beach is surrounded by sand dunes and Cedar Forest, giving it a wild, untouched beauty. For windsurfing and kitesurfing, Mikri Vigla Beach is the go-to spot for thrill-seekers.

I spent a lazy afternoon at Plaka Beach, alternating between swimming in the calm, shallow waters and enjoying a cold frappé at a seaside café. Unlike Mykonos or Santorini, Naxos has a more relaxed vibe, making it perfect for unwinding. Whether you’re looking for adventure, seclusion, or a lively atmosphere, the beaches of Naxos have something for everyone to enjoy.

9. Explore Rhodes’ Medieval Old Town

Walking through Rhodes’ Medieval Old Town feels like stepping back in time. A UNESCO World Heritage Site, this well-preserved medieval city is packed with cobblestone streets, fortified walls, and stunning Gothic architecture. The Palace of the Grand Master is a must-see, offering a glimpse into the island’s history during the Knights of St. John era. Wander along the Street of the Knights, where inns housed warriors from across Europe, and explore Sokratous Street, filled with shops selling handmade crafts, spices, and local olive oil.

I got lost in the labyrinth-like alleys, discovering hidden courtyards and charming cafés along the way. By night, the town comes alive with tavernas and wine bars, offering the perfect setting for a relaxing evening. Whether you’re a history lover, foodie, or just looking for an unforgettable walk, Rhodes’ Old Town is an absolute must-visit.

10. Ikaria’s Thermal Springs

Ikaria, known as “the island where people forget to die,” is famous for its longevity and natural thermal springs. Found near Agios Kirykos and Therma, these mineral-rich waters have been used for centuries to relieve joint pain, skin conditions, and stress. The most popular spot, Radio Nero, offers steaming natural pools right by the sea, creating a unique spa-like experience in nature.

I visited Therma, where the warm waters flow into the sea, blending cool and hot currents for a relaxing dip. The locals swear by the healing powers of these springs, and after just an hour, I felt completely rejuvenated. If you’re looking for a wellness retreat, a stop at Ikaria’s thermal springs is a must. It’s not just about relaxation, it’s about experiencing the island’s secret to a long, healthy life.

11. Sifnos’ Panigiri

If you want an authentic Greek experience, attending a Panigiri (traditional festival) in Sifnos is a must. These summer celebrations, often held in small village squares or monasteries, bring locals and visitors together for live music, dancing, and endless plates of local food. The biggest and most famous is the Panigiri of Prophet Elias, held every July, where guests hike up to a mountaintop monastery before feasting on chickpea stew, roasted lamb, and wine under the stars.

I stumbled upon a Panigiri in Artemonas, where I was instantly welcomed with homemade food and traditional island music. The energy was contagious—locals danced, laughed, and toasted with raki late into the night. It’s one of those experiences that turns visitors into friends and gives you a deeper appreciation for Greek culture. If you’re in Sifnos in summer, don’t miss it.

12. Temple of Poseidon in Sounion

Perched on a cliff overlooking the Aegean Sea, the Temple of Poseidon in Cape Sounion is one of the most breathtaking historical sites in Greece. Dating back to 440 BC, this ancient temple was dedicated to Poseidon, the god of the sea, offering sailors a final blessing before their voyages. As the sun sets, the temple’s white marble columns glow against the sky, creating an unforgettable scene.

I arrived just in time for sunset, and the view was beyond magical. The Aegean stretched endlessly below, and the temple ruins stood as a reminder of Greece’s deep maritime history. Many visitors bring a bottle of wine and watch the sky turn orange and pink as the day fades away. Whether you’re a history buff, photographer, or hopeless romantic, the Temple of Poseidon is one of the best sunset spots in Greece.
