The Enchanting Harbor Town of Symi

While Rhodes typically captures most visitors’ attention in the Dodecanese islands, the nearby gem of Symi offers a mesmerizing alternative that shouldn’t be missed.

Though Rhodes dazzles most travelers, neighboring Symi beckons with mesmerizing charm that deserves your wanderlust.

As your ferry approaches, you’ll be greeted by a breathtaking amphitheater of pastel-colored Italian-style houses cascading down the hillsides.

The harbor town, legally protected since 1971, retains its authentic charm with vibrant facades that photographers adore.

You’ll find the 19th-century Timiou Prodromou Monastery and historic Clock Tower enhancing the picturesque setting.

Once a thriving shipbuilding and sponge harvesting center, Symi now welcomes travelers to its relaxed waterfront lined with boutiques and tavernas. Much like Lefkada’s idyllic beauty, Symi offers a truly authentic Greek island experience without overwhelming crowds. The town is divided into two main sections: Chorio and Gialos, each offering unique historical and cultural experiences.

Don’t leave without trying the famous Symi shrimps—small, crispy delicacies eaten whole—while watching yachts bob gently in one of Greece’s most beautiful natural harbors.

Karpathos: A Haven of Pristine Beaches and Mountain Villages

Beyond the colorful facades of Symi lies another Dodecanese treasure waiting to be explored. Karpathos, nestled between Rhodes and Crete, offers an authentic Greek experience with its well-preserved traditions and unique dialect.

You’ll discover a diverse landscape where mountainous terrain meets pristine white beaches. The island’s highest peak, Kali Limni, towers at 1,215 meters, while the Korifi Mountains divide the island into distinct northern and southern regions.

Venture west to find pine-covered coastlines or explore the relatively flat Afiartis plain in the south. The island’s captivating history dates back to ancient times when Homer referred to it as Krapathos in Iliad.

Don’t miss the traditional mountain village of Olympos, where ancient lifestyles still thrive. With crystal-clear waters, secluded coves, and a population of just 6,567, Karpathos offers a peaceful retreat from the crowds. Regular ferry services connect you to this idyllic destination. Many travelers find Karpathos to be a must-visit destination for those seeking authentic Greek culture away from touristy hotspots.

Kalymnos: Paradise for Rock Climbers and Nature Lovers

Nestled in the heart of the Dodecanese archipelago, Kalymnos emerges as a rugged paradise that draws adventure seekers from around the world. This mountainous island, spanning 111 square kilometers, has earned international acclaim for its exceptional rock climbing opportunities.

You’ll find a climber’s haven with diverse routes suitable for all skill levels among the three mountain ranges and dramatic limestone cliffs. The island’s highest peak, Profitis Ilias, reaches 760 meters above sea level and offers breathtaking panoramic views. When you’re not scaling heights, explore the island’s 96km coastline with its deep fjord-like coves and crystal-clear waters.

The western villages of Myrties, Massouri, and Panormos offer comfortable accommodations and organized beaches. Unlike the famous caldera views of Santorini’s Fira, Kalymnos provides a more untouched, natural landscape to admire. Don’t miss the chance to visit surrounding islets like Télendos, once connected to Kalymnos until an earthquake separated them in 554 AD.

Historical Wonders and Natural Beauty of Kos

Just a short ferry ride from Kalymnos, the island of Kos enthralls visitors with its remarkable blend of ancient history and natural splendor. You’ll step into antiquity at the Asclepieion, where Hippocrates once taught medicine, or wander through the Ancient Agora‘s well-preserved ruins dating back to the 3rd century BC.

Don’t miss the imposing 14th-century Knights’ Castle with its dual fortifications and palm-lined approach. For natural beauty, visit Therma Beach‘s therapeutic volcanic hot springs or hike Dikeos Mountain for panoramic Aegean views. The 500-year-old Hippocrates’ Plane Tree offers cool shade in Kos Town. Many visitors recommend taking one of the popular 3-Island boat cruises that depart from Port of Kos for an unforgettable day of swimming and exploration.

Architecture enthusiasts will appreciate the multicultural landscape featuring Ottoman mosques, Byzantine basilicas, and elegant Italian-era buildings that showcase the island’s diverse heritage through the centuries. Travelers can enhance their experience by learning some basic Greek phrases which locals appreciate and which help navigate this culturally rich destination.

Halki (Chalki): The Peaceful Gem of the Dodecanese

Located only 9 km west of Rhodes, Halki stands as the Dodecanese’s tranquil jewel with fewer than 500 permanent residents calling it home. This car-free island offers an authentic escape from modern life, with colorful neoclassical houses lining Emporio’s picturesque harbor.

Halki invites you to step back in time on a serene Aegean isle where simplicity and beauty reign supreme.

You’ll find pristine waters at Pondamos Beach or the more secluded Kania Beach, both boasting remarkable 30-meter visibility for snorkeling. Since the island has virtually no natural water, visitors should bring their own drinking water or purchase bottled water that arrives from Rhodes. Explore the abandoned village of Chorio and climb to the Knights of St. John fortress ruins for breathtaking views.

The island’s progression from sponge fishing to slow tourism preserves its genuine character. Sample local makarounes pasta and join July’s Fisherman’s Feast for a taste of island culture. The alluring atmosphere of Halki makes it one of the most worthwhile day trips from Rhodes for those seeking authentic Greek island charm.

With limited accommodations in family-run guesthouses, Halki promises an uncrowded, peaceful retreat.

Kastellorizo: Greece’s Easternmost Island Escape

You’ll find this island uniquely mesmerizing with:

• Dramatic red cliffs contrasting against the deep blue Mediterranean
• Historic Castle of the Knights of St. John overlooking the harbor
• Ancient Lycian tombs carved directly into coastal rock formations
• Charming fishing village with colorful neoclassical houses
• Crystal-clear waters perfect for swimming and snorkeling

Though challenging to reach—requiring either a four-hour ferry or 40-minute flight from Rhodes—Kastellorizo’s remoteness preserves its authentic character and unhurried pace. The island offers a peaceful alternative to the historical sites found in Athens and mainland Greece. Situated just 2 km from Turkey, this easternmost Greek island offers breathtaking views across international waters.

Planning Your Island-Hopping Adventure From Rhodes

While Kastellorizo represents a singular jewel in Greece’s island crown, Rhodes serves as the perfect gateway to a treasure trove of nearby islands. You’ll find year-round access to the diverse Dodecanese archipelago, with summer bringing additional connections to the Cyclades.

For seamless exploration, use services like Ferryhopper to organize your routes or consider package deals that combine travel and accommodations. If you’re short on time, Symi makes an ideal day trip with its stunning harbor views.

For longer adventures, include Kos for its beaches and nightlife, Kalymnos for rock climbing, or peaceful Halki for serene landscapes. Karpathos offers untouched nature perfect for hiking enthusiasts who want to explore authentic Greek villages.

Consider traveling during shoulder seasons when you’ll encounter fewer crowds and lower prices while still enjoying pleasant weather and reliable ferry connections. The ferry network between Greek islands expands significantly during peak summer months, offering more frequent departures and additional route options.

The Sum Up

Like pearls scattered across the Aegean, these seven islands offer unique treasures just waiting to be discovered. You’ll find it easy to arrange day trips or overnight stays from Rhodes, with regular ferry connections to most destinations. Don’t rush—each island deserves time to explore. Pack light, bring sunscreen, and embrace the laid-back island rhythm that makes the Dodecanese so magical.
