Platja Gran, Sandy beach near Vila Vella in Tossa de Mar, Spain.

Platja Gran, also called sa Platja, is the beach at the centre of Tossa de Mar, in the bay of the same name. It runs 381 m east-facing, with an average width of 74 m of coarse pinkish sand and a steep entry into the water. A rocky point leads east to Mar Menuda beach, the Cap de Tossa closes it to the west, and the Tossa stream reaches the sea at its southern edge, es Racó. A promenade with restaurants and bars runs behind it.

The beach sits at the foot of the Vila Vella, the walled old town whose perimeter walls and towers were built from the 12th century onward on the headland of Cap de Tossa. The fortifications were raised to guard the bay against pirate raids, and their silhouette above the sand remains the defining feature of the cove.

Fishermen still haul their boats onto the sand at Platja Gran, since Tossa de Mar has no harbour for them. The beach takes its other name, sa Platja, from local speech, and the riera de Tossa reaches the sea at its southern edge, at a spot called es Racó. At the northern end stands Frederic Marès's sculpture Minerva, listed in Catalonia's architectural heritage inventory.

The beach is easy to visit and has showers, restrooms, and lifeguards during the warmer months. The promenade behind it is flat and well-accessible with plenty of places to eat and rest.

Boat tours with glass bottoms depart from the beach to nearby coves, allowing views of fish and underwater rock formations. This experience draws many visitors who want to see marine life without diving.
