Yıldızkoy: Guide to Gökçeada's Underwater National Park and Unique Rocky Cove

Hidden among 40-million-year-old rocks at the heart of Turkey's first and only Underwater National Park, Yıldızkoy is a cove shaped by the mighty northern winds on Gökçeada's north coast. Here, the sea is not just a swimming spot — it's a living underwater ecosystem, a geological treasure, and a stargazing observatory at night.

Where is Yıldızkoy and Why Is It So Special?

Yıldızkoy (also known locally as Yıldız Koyu) is located on Gökçeada's north coast, about 3 km from the village of Bademli (Yeni Bademli). It's roughly 15 km by car from Gökçeada town center and about 15 minutes from the ferry dock. Its northern location defines the cove's character: it faces the dominant Aegean wind, the poyraz (northerly), earning it a reputation as a "windy cove."

But what truly makes Yıldızkoy unique is not just its geography. This cove lies within the Gökçeada Underwater National Park, protected since 1999 by the Turkish Marine Research Foundation (TÜDAV). As the only point where you can enter the park from land, Yıldızkoy offers the most natural and authentic access to the protected area. Fishing and spearfishing are strictly prohibited, allowing underwater life to thrive exceptionally.

The Underwater National Park: 144 Fish Species, 40-Million-Year-Old Rocks

The Gökçeada Underwater Marine Park covers a 1.5-mile stretch of coastline from Yıldızkoy to Çiftlik Koyu. Scientific studies by TÜDAV have revealed incredible biodiversity beneath the surface:

• 144 fish species — extremely dense populations thanks to the fishing ban
• 34 sponge species — rich sponge communities on the rocky seabed
• 17 cephalopod species — octopus, cuttlefish, squid
• 8 marine mammal species — endangered Mediterranean monk seal (Monachus monachus) and dolphins
• Posidonia oceanica — endemic seagrass known as the lungs of the Mediterranean
• Caretta caretta — endangered sea turtle

Gökçeada sits at a unique transition point between the Mediterranean and Black Seas. This location blends water temperature and salinity, creating exceptional biodiversity that hosts species from both seas.

Beyond the underwater world, the cove's rocks are a treasure for scientists. Listed among UNESCO Turkey's 100 Geosites, these rocks are approximately 40 million years old (Eocene period). Sandstone sculptures, fault planes, fault breccias, and honeycomb textures in the Mezardere Formation hold great geotourism value. Silicified wood fossils are also listed in Turkey's 100 Geological Heritage sites.

What's the Beach Like? How to Enter the Sea?

The most important thing to know before visiting Yıldızkoy: this is not a sandy beach. The ground is entirely pebbly and rocky. Therefore, water shoes are absolutely essential — don't go without them.

So why is it a favorite for so many? Because the sea is indescribably clear. The phrase "like an aquarium" might sound cliché, but at Yıldızkoy it truly fits. The water is shallow, visibility is extraordinary, and every stone, fish, and marine plant below can be seen with the naked eye. A floating dock/platform installed in 2012 allows easy entry without climbing over rocks. Sunbathing on the rocks and descending via stairs is also popular.

As for the wind: when the northerly (poyraz) blows, waves rise and swimming can become difficult. On days with southerly winds, the same sea becomes "flat as a sheet." So before heading to Yıldızkoy, checking the wind forecast is crucial for both safety and enjoyment. July and August are the busiest months, but swimming is suitable from early June to late September.

Snorkeling: One of Turkey's Best Spots

The most tangible benefit of being inside the Underwater National Park is the extraordinary snorkeling experience. In these no-fishing waters, fish are unafraid of humans and may surround you as you swim. Spending 30 minutes among seagrasses, sponge colonies, and colorful rocks can be one of the most unforgettable underwater moments of your life.

Bring your own snorkel set. Rental options at the cove may be limited. For scuba diving, you need to work with authorized diving schools and obtain necessary permits. Spearfishing is strictly prohibited and subject to heavy penalties.

Yıldızkoy Arkadia Campground

When it comes to accommodation at the cove, the most well-known name is Yıldızkoy Arkadia Campground. Founded by three friends, this boutique facility ranks #1 among 4 campgrounds on Gökçeada on TripAdvisor.

You can bring your own tent or use the facilities. Services for campers include:

• Hot water, showers, and toilets
• Dishwashing area and washing machine
• Shared refrigerator and charging points
• Wi-Fi connection
• Sun loungers and umbrellas (free for campers)

Operating as a beach-restaurant by day, the facility transforms in the evening: live music, DJ performances, fire shows, and a Reggae-themed atmosphere enliven the cove's nights. The bar is open until 2:00 AM. Camping prices vary by season, so check yildizkoy.com or the @yildizkoyarkadia Instagram account for current info.

There is also a second beach-restaurant facility operating at the cove. Both offer sun lounger and umbrella rentals.

Historical Structures: Chapel, Castle, and Monastery

Yıldızkoy stands out not only for its natural beauty but also for its historical traces. During a walk around the cove, you'll encounter:

• Historic chapel: Its outer walls still standing, a silent witness to the Greek Orthodox heritage of the cove.
• İskiter Castle: On the left side of the cove, ruins of a Genoese-era castle.
• Monastery ruins: On the right side of the cove, remnants of a monastery.
• Samothrace (Samothraki) view: Looking out to sea, you can see the Greek island of Samothrace on the horizon.

Astro-Tourism: Gökçeada's Best Spot for Stargazing

Yıldızkoy may not have been named randomly. With almost zero light pollution, the night sky here opens up with a clarity you'll never see in the city. A visitor experience shared by Gökçeada İmroz Magazine sums it up best: "At Yıldız Koy, on the rocks past the chapel, I saw the stars so clearly for the first time in my life."

If you camp overnight, just get up at midnight and head to the rocks. Even without a professional telescope, you can clearly see the Milky Way. For photography enthusiasts, long-exposure shots promise great rewards.

Nearby Attractions: Mavi Köy, Aşıklar Koyu, Bademli

Yıldızkoy is surrounded by beauty worth exploring:

• Mavi Köy and Aşıklar Koyu: Accessible via a path on the right side of the cove. A scenic and quiet trekking route.
• Bademli (Yeni Bademli) Village: Just 3 km away. The village's stone houses and quiet streets are worth a short visit.
• Kaleköy: You can walk from Yukarı Kaleköy to Yıldızkoy via a trail; challenging but scenic.
• Gökçeada Ultra Trail Route: The international ultra trail running route passes through the cove, described as "rocks challenged by waves."

Also worth visiting is Mavi Köy, known for its proximity to the Underwater National Park.

Environmental Concerns and Conservation Awareness

Being a conscious visitor is crucial when visiting the Underwater National Park. Researchers have detected 3-4 microplastics per liter of water in the park. While this is low by global averages, it's notable for a pristine ecosystem. When visiting Yıldızkoy, following these rules is both a legal obligation and an ethical responsibility:

• Fishing and spearfishing are strictly prohibited
• Do not touch marine life or break corals
• Take your trash back; do not throw it into the sea
• Protect underwater plants (Posidonia)

How to Get There

Private car or rental car is the most practical way to reach Yıldızkoy. There is no regular public transport.
