San Lorenzo Beach is Melilla's most convenient swim, a city beach beside the marina with golden sand, calm-to-moderate water, and the practical services you want when the beach is part of an urban day. It is not wild or secluded, but that is not the point.
Use it as a cooling-off stop between Melilla la Vieja, the modernista centre, and the port. Its central location makes it easy to drop in for an hour, and the promenade setting gives a quick sense of how tightly Melilla's beaches, monuments, and everyday city life are packed together.
