Ahoy Crew!
Grab your maps and magnifying glasses — today we’re sailing into the magical geography of San Sebastián, Spain, where golden beaches, green hills, and rocky islands meet in one of the most beautiful bays in the world.
Welcome to La Concha Bay, the sparkling crescent that wraps Captain PillowBelly in waves, wonder, and just the right amount of sunshine.

🏖️ What’s a Crescent Bay?
A crescent bay is a curved stretch of coastline that looks like a smile from above. The word concha even means “shell” in Spanish — and La Concha Bay truly looks like a shiny seashell cradling the sea!
These bays form naturally over thousands (or even millions!) of years. The wind and waves slowly shape soft parts of the coastline into smooth arcs, while harder rocks stay strong, creating shelter on each end.
Why does this matter?
Because that natural shape creates gentle waves, safe swimming, and sandy shores — perfect for a relaxing day of play and napping (Captain PillowBelly-approved!).
🌄 What Makes San Sebastián’s Geography So Unique?
Let’s look at the amazing mix of land and sea that makes this Spanish seaside city so special:
🟢 La Concha Beach – a protected crescent that faces north into the Bay of Biscay but feels as calm as a lagoon
🪨 Mount Igueldo & Mount Urgull – two tall hills that guard the bay like sleepy giants, offering epic views and protecting it from harsh winds
🌴 Santa Clara Island – a tiny island right in the middle of the bay! At low tide, a hidden sand path appears so you can walk across the sea like magic
🏞️ Basque Mountains – not far from the beach, the rolling green hills rise quickly into mountain ranges that shape the city’s climate and culture
San Sebastián is a rare city where ocean, island, mountains, and historic buildings all fit together like puzzle pieces — and that makes it a dreamland for little explorers.
🐾 A Pillow-Sized Lesson
Captain PillowBelly learned that geography isn’t just about land and water — it’s about how those features shape how people live, what they eat, how they travel, and even how they celebrate.
In San Sebastián, the geography brings families to the beach, gives surfers perfect waves nearby, shelters boats in the harbor, and offers hikers views from above. All in one city!
Next time you see a beach shaped like a smile, remember: Earth’s geography has its own way of giving hugs.
