Top 10 Hidden Beaches in Spain (Where the Crowds Still Haven’t Found You)

By Reserra Book — Travel Smarter. Travel Beautifully.

Spain is known for its golden coasts and iconic resort towns — but some of its most breathtaking beaches are tucked away in quieter coves, secret bays, and rugged coastal hideaways known mainly to locals. If you’re craving turquoise waters, dramatic cliffs, and that slow Mediterranean rhythm (without the crowds, noise, or overbuilt boardwalks)… this list is for you.

Below are 10 hidden beaches across Spain — with Mallorca’s Cala Deià taking the #1 spot for its cinematic beauty and timeless Mediterranean calm.

1. Cala Deià (Mallorca, Balearic Islands)

Best for: Stone-bay swimming, coastal sunsets, artist’s hideaway feeling.
Vibe: Warm Mediterranean romance layered into ancient stone and turquoise coves.

On the northwest coast of Mallorca lies Cala Deià, a small pebbled cove framed by dramatic cliffs, fishing huts, and pine trees clinging to the hillside. It doesn’t feel discovered — even though it sits near the beloved village of Deià (once home to poets, painters, and writers). The water glows in tones of deep emerald and sapphire, and evenings here often bring golden-hour swimmers floating quietly as the sun slides behind the cliffs.

Insider Tip: Time your visit late afternoon and stay for dinner at one of the two rustic seafood restaurants built directly into the rocks — it’s one of the most romantic dining settings in Spain.

2. Playa de Gulpiyuri (Asturias)

A surreal hidden inland beach that sits behind rolling green hills — connected to the Bay of Biscay by underwater cave channels. When the tide rises, waves surge into a sandy hollow surrounded by countryside fields. It feels like stepping into a fantasy novel.

3. Cala Macarelleta (Menorca)

Crystal-clear lagoon waters, white limestone cliffs, and a curved cove shaped almost perfectly by nature. The water here looks Caribbean — and still avoids the crowds of Mallorca’s main beaches.

Go Early: Morning light turns the water into pure watercolor blues.

4. Praia das Catedrais (Galicia)

Known as the Cathedral Beach, this otherworldly stretch reveals towering stone archways when the tide is low. It’s dramatic, raw, and unforgettable — like wandering inside a natural stone cathedral carved by waves.

5. Playa del Silencio (Asturias)

A sweeping crescent of polished stones, calm waves, and cliff-lined seclusion. There are no restaurants, shops, or facilities — and that’s what keeps it beautifully quiet.

6. Cala d’en Serra (Ibiza)

Yes — Ibiza still has secrets.
Tucked in a sheltered bay in the north, Cala d’en Serra feels worlds away from the nightlife scene. Bring your snorkel — the underwater visibility is incredible.

7. Playa de Monsul (Almería)

A volcanic beach surrounded by surreal rock formations and soft black-gold sand. It’s wide, cinematic, and untouched — famously used as filming location for classic adventure films.

8. Cala del Moraig (Costa Blanca)

A cliff-backed cove with translucent turquoise waters. Follow a hidden path into La Cova dels Arcs, a natural rock archway with views straight across the sea.

9. Cala Trebalúger (Menorca)

To reach this beach, you’ll hike through forest paths, cross a stream, and descend to a quiet cove of white sand and deep green waters. The journey makes the arrival feel like a secret meant only for you.

10. Playa de Bolonia (Tarifa, Andalusia)

Wide, wind-brushed sands and ancient Roman ruins just steps from the shore. Climb the sweeping dunes for one of the most impressive coastal views in southern Spain.

Closing — Travel Beautifully

The most unforgettable moments in Spain aren’t always in the famous plazas or crowded resorts — they’re found in quiet coastlines, hidden coves, and evening swims beneath cliffs that glow in the last golden light of the day.
