14 Secret Beach Destinations That Aren’t Overcrowded Yet

5. Playa de Gulpiyuri – Spain’s Beach Without a Sea

This unique inland beach is one of Spain’s most incredible natural wonders. Located 100 meters from the coastline, Playa de Gulpiyuri is a tiny, hidden cove surrounded by lush green meadows. The beach is fed by seawater through underground tunnels, creating a surreal, ocean-like lagoon with soft golden sand. Despite its extraordinary beauty, Gulpiyuri remains relatively unknown outside Spain, largely due to its small size and secluded location. It’s a rare geological marvel that feels like a secret paradise tucked away in northern Spain.
