KASTRO BEACH
Everything You Need to Know
Kastro Beach is an extraordinary coastal spot located at the northernmost tip of Skiathos. The beach sits directly underneath the monumental rocky peninsula where the medieval capital of the island stood from the 14th to the 19th century. Kastro combines dramatic geological beauty with profound history; after sunbathing on its pebbly shores, you can hike up the steep path to explore old churches, ruins, and the historic iron gate of the fortress.
Where to Eat & Drink
Despite its remote and historic nature, you can enjoy an authentic bite right on the beach:
Kastro Beach Canteen
A rustic, wood-built small tavern operating directly on the pebbles. It serves simple Greek staples like Greek salad, souvlaki, fresh fries, cold beer, and frappe coffees. It operates under a shaded canopy, offering a perfect resting point before or after your climb to the medieval ruins.
Authentic CantinaActivities & Exploration
To preserve the historical dignity and tranquility of the site, there are no motorized water sports or commercial rentals on Kastro. The main highlights are historical and natural:
Explore the Medieval Castle
A steep but unforgettable 20-minute uphill hike leads you straight into the ruins of Kastro. You can explore the remnants of old houses, mosques, and standing Byzantine churches while enjoying jaw-dropping 360-degree panoramic views of the Aegean Sea.
Snorkeling & Swimming
The waters at Kastro are exceptionally clear and drop off rapidly into the deep blue. The rocky outer reefs are bursting with marine life, making it one of the premier spots on the island for snorkeling.
Beach Setup & Vibe
Kastro faces the open northern sea, meaning it is prone to large, rolling waves when the northern Meltemi winds blow. On calm days, it is a peaceful paradise.
- Sunbeds: The small beach canteen provides a limited number of basic umbrellas and sunbeds for rent, but there is plenty of open space to lay down your own towel.
- Footwear: The beach consists of coarse sand and medium-sized pebbles. Sturdy shoes are required for the hike up to the castle, and water shoes are highly recommended for entering the sea.
- Crowds: The beach sees waves of visitors between 11:00 AM and 3:00 PM when excursion boats stop by, but remains incredibly quiet in the morning and late afternoon.
How to Get There
There are two primary ways to reach Kastro Beach. The easiest and most popular option is taking a **daily excursion boat** from the Old Port of Skiathos Town. Alternatively, you can drive via a bumpy dirt road to a parking area near Kastro and then take a **steep, winding 25-minute downhill walk** along a stone path. A 4x4 vehicle or robust ATV is highly recommended if choosing the land route.
💡 Insider Tip from Locals
If you decide to hike up to the fortress, **do it early in the morning** or late in the afternoon. The midday sun bouncing off the white stones can make the climb exhausting. Always bring proper athletic shoes for the hike—flip-flops are highly dangerous on the slick, steep castle paths. Also, **bring cash** for the beach canteen, as remote network coverage means card machines rarely work here.
Emergency Info: The land path is steep and isolated. In case of slips or heat exhaustion, coordinate help through the canteen staff or call 112. Always carry a bottle of water during the castle hike.
