Located in Piélagos, Beach of Arnia is a picturesque beach known for its striking landscapes and golden, fine sand. It is nestled close to Liencres and offers breathtaking views of the Cantabrian Sea. The beach features dramatic rock formations, with a prominent rock standing on the left side that shelters it from wind and waves. Opposite the beach is Castro Island, adding to its scenic beauty. Despite its natural appeal, the beach has limited amenities but offers access to nearby attractions and dining options. It has been recognized for its cleanliness by the Community of Cantabria.
The tranquil ambiance of the beach makes it perfect for relaxation and admiring nature. However, it is not ideal for building sandcastles or sunbathing due to its rugged surroundings.
