15 Unique Places to Visit in Spain Even Locals Don’t Know About
Spain is full of hidden gems waiting to be discovered—places even many locals have never heard of. Beyond the famous sights, there are remote villages, stunning natural wonders, and historical sites that feel like stepping into another world.
If you love exploring off-the-beaten-path destinations, these 15 unique places in Spain will add unforgettable memories to your travels. From secret islands to mysterious caves, get ready for an adventure you won’t find in the guidebooks.
1. Cueva de los Tayos, Basque Country
Tucked away in the lush forests of the Basque Country, this little-known cave system is a dream for adventure seekers. Inside, you’ll find impressive rock formations, underground lakes, and ancient carvings that hint at its prehistoric past.
Unlike Spain’s more famous caves, Cueva de los Tayos remains largely untouched. The best way to explore is with a local guide who can take you through its hidden chambers—some of which have never been fully mapped.
2. El Acebuchal, Andalusia
Known as the “Lost Village of Andalusia,” El Acebuchal was abandoned after the Spanish Civil War and only recently restored. Hidden in the mountains near Frigiliana, this charming hamlet feels frozen in time, with whitewashed cottages, cobblestone streets, and no modern distractions.
Visit in the early morning for a peaceful walk through the village, then enjoy a meal at the famous Bar El Acebuchal, where traditional Andalusian dishes are made using century-old recipes.
3. Bufones de Pría, Asturias
Along the rugged coast of Asturias, these natural blowholes create an awe-inspiring spectacle. When the tide is high, seawater shoots up through the rock formations like geysers, reaching up to 20 meters in the air.
The best time to witness this natural wonder is during stormy weather when the waves crash against the cliffs with full force. Bring sturdy shoes and explore the nearby coastal trails for breathtaking ocean views.
4. Setenil de las Bodegas, Cádiz
Unlike any other village in Spain, Setenil de las Bodegas is built directly into massive rock overhangs. Houses, bars, and shops are carved into the cliffs, creating a surreal scene that blends nature and architecture.
Stroll through the narrow streets, stopping for tapas at La Tasca, where you can dine under a natural rock ceiling. Don’t forget to walk up to the castle ruins for panoramic views of the surrounding countryside.
5. Isla de Ons, Galicia
While the Cíes Islands draw most of the attention, Isla de Ons remains a quiet escape for those in the know. Located in the Atlantic Islands of Galicia National Park, it boasts pristine beaches, hiking trails, and some of Spain’s freshest seafood.
The island is only accessible by boat from Bueu during the summer months. For a true local experience, stay overnight in one of the few rustic accommodations and enjoy a plate of polbo á feira—Galicia’s famous octopus dish.
6. Mont-Rebei Gorge, Catalonia
If you’re looking for a jaw-dropping hike, Congost de Mont-Rebei is the place to go. A narrow path carved into the cliffs offers breathtaking views of the turquoise river below, with suspension bridges adding an extra thrill.
Kayaking through the gorge is another incredible way to experience its beauty. Go in the early morning or late afternoon to avoid crowds and see the golden light reflecting off the canyon walls.
7. Bardenas Reales, Navarre
This otherworldly desert landscape looks like it belongs on Mars rather than Spain. The Bardenas Reales Natural Park is a vast expanse of eroded clay formations, canyons, and plateaus, perfect for exploring by bike or on foot.
One of the most famous landmarks is Castildetierra, a unique rock formation that has become a symbol of the park. Visit at sunrise or sunset when the golden light transforms the landscape into a photographer’s dream.
8. Pozas de Melón, Galicia
These hidden natural pools in Galicia are a dream come true for wild swimming lovers. Surrounded by lush greenery and waterfalls, the Pozas de Melón feel like a secret paradise far from the tourist crowds.
The best time to visit is in late spring or early summer when the water is refreshing but not too cold. Pack a picnic and spend the day hopping between pools, enjoying the peaceful atmosphere.
9. Peratallada, Catalonia
A fairytale medieval village straight out of a storybook, Peratallada is one of Catalonia’s best-kept secrets. Its stone houses, winding alleys, and ivy-covered walls make it one of Spain’s most picturesque places.
For a true taste of the region, visit in autumn when the nearby vineyards turn golden. Enjoy a leisurely meal at Can Bonay, a family-run restaurant serving Catalan cuisine in a 13th-century building.
10. Cala San Pedro, Almería
For those who love remote beaches, Cala San Pedro is an adventure worth taking. Accessible only by a hike or boat ride, this unspoiled bay offers crystal-clear waters, golden sand, and even a small community of off-grid residents.
Bring plenty of water and supplies, as there are no modern facilities. The best time to visit is early in the morning before the sun gets too strong.
11. La Garrotxa Volcanic Zone, Catalonia
Yes, Spain has volcanoes! The La Garrotxa Volcanic Zone Natural Park is home to over 40 extinct volcanic cones, covered in lush forests and hiking trails.
One of the best hikes takes you to the Santa Margarida Volcano, where you’ll find a picturesque chapel sitting inside the crater. Visit in autumn when the fall foliage creates a magical atmosphere.
12. Cueva del Tesoro, Málaga
Unlike most caves in Spain, Cueva del Tesoro is a marine cave formed by the sea. Legends say it hides an ancient treasure, though its true beauty lies in the crystal-clear pools, eerie rock formations, and prehistoric paintings.
Located near the coastal town of Rincón de la Victoria, this cave is one of the only marine caves in Europe open to the public. Visit during low season for a more intimate experience.
13. Castillo de Zafra, Guadalajara
Game of Thrones fans might recognize Castillo de Zafra as the Tower of Joy from the series. This medieval fortress sits dramatically on a rocky hill, surrounded by the vast landscapes of La Mancha.
Since it’s in a remote area, you’ll likely have the castle all to yourself. Visit during golden hour for stunning views and an almost mystical atmosphere.
14. Fageda d’en Jordà, Catalonia
A magical beech forest in the heart of a volcanic region, Fageda d’en Jordà is straight out of a fairytale. The trees take on a dreamy golden hue in autumn, making it one of the most beautiful spots in Spain.
A network of trails winds through the forest, perfect for peaceful walks, horseback riding, or even hot air balloon rides over the volcanic landscape.
15. Río Tinto, Andalusia
If you’ve ever wanted to visit another planet, Río Tinto is as close as it gets. The river’s deep red waters and surreal rock formations create a Martian-like landscape, shaped by centuries of mining.
NASA has even studied this area for its similarities to Mars! The best way to explore is by taking a scenic train ride through the region, learning about its fascinating history.
