Blue Lagoon

Blue Lagoon sits on the Apostelogianni road in Kastraki, a long, low-key beach settlement on the southwest coast of Naxos. It faces the water directly, which makes it one of the more straightforward choices along this stretch if you want a proper meal with a sea view rather than just a sun-lounger snack.

With a 4.6-star rating across 468 Google reviews, Blue Lagoon has built a consistent reputation among both island regulars and passing visitors. The social media presence — under the handle @blue_lagoon_food_n_drinks — positions it as a food-and-drinks operation that also handles breakfast and brunch, so the kitchen runs for a longer stretch of the day than a typical taverna.

What to Expect

The menu centers on fresh seafood and Greek dishes, the two things Naxos does best. Expect the standard lineup of grilled fish by the kilo, calamari, and mezedes alongside heartier plates of meat grills and salads built around local produce — Naxos is unusually well-supplied with its own potatoes, cheese, and vegetables, so side dishes here tend to be better than on smaller, less fertile islands.

The setting is casual and beachside. Kastraki is a quieter alternative to the more developed Agios Prokopios and Agia Anna beaches to the north, so the atmosphere here leans relaxed rather than buzzy. Tables are positioned to take in the Aegean view, and the kitchen covers breakfast through to evening meals, making it flexible for different schedules.

How to Get There

Kastraki is roughly 8 km south of Naxos Town (Chora). By car or scooter, take the coastal road south past Agios Prokopios and Agia Anna; Kastraki begins shortly after. Blue Lagoon is on Odos Apostelogianni, the main road running through the settlement — look for it on the seaward side.

The KTEL bus from Naxos Town runs a route down the west coast that stops at or near Kastraki; check current timetables at the main bus terminal near the port, as schedules vary by season. Parking along the Kastraki road is generally manageable outside of peak August weeks. There are no entry fees — it's a restaurant, not a ticketed site.

Best Time to Visit

Blue Lagoon operates through the main tourist season, roughly May through October, with the busiest period running from late June to late August. Lunch service during peak season can get crowded on weekends, so arriving before 13:00 or after 14:30 gives you a more relaxed experience. Sunset dinners here are popular — Kastraki faces west, so the light on the water in the early evening is a genuine draw. Shoulder season visits in May, June, or September offer the best combination of good weather and manageable crowds.

Tips for Visiting

• Call ahead in high season: The phone number is +30 2285 075147. A quick call to reserve a table facing the water is worth it in July and August.
• Go for the local catch: Ask what fish came in that day rather than defaulting to the printed menu — freshness varies, and the staff will usually tell you straight.
• Budget for a full meal: The pricing appears to sit at the higher end of casual beachside dining (noted as "$$" in aggregator listings), so factor that in if you're watching costs.
• Combine with the beach: Kastraki beach is directly accessible from the restaurant area. Arrive early, spend time on the sand, and move to a table for lunch without needing to drive anywhere.
• Follow their Instagram: @blue_lagoon_food_n_drinks posts food and seasonal updates — useful for confirming they're open if you're visiting in the shoulder months.

What's Nearby

Kastraki beach itself stretches for a couple of kilometres and is significantly less developed than the beaches immediately north. The dunes behind the southern end of Kastraki are part of a protected coastal zone. Plaka beach begins where Kastraki ends and continues further south toward Alyko — both are worth exploring if you have a car or scooter. The ancient marble quarries at Flerio and the Temple of Demeter at Gyroulas are inland day-trip options from this part of the island.
