Caminada Nocturna Solidària is a night charity walk in Calafell. It begins at L'Estany in Plaça Països Catalans and concludes by the sea at La Mar Salada Beach Club in the Sector Sanatori area. Participants are asked to wear white, creating a unified appearance from the start.
The route leads from the town meeting point down to the beach club finish, where a white party follows. The Mas Romeu Drum and Fife Band accompanies the walk, providing music. The event raises support for the Catalan League Against Cancer. A gift raffle is also held, with a 2 euro donation per ticket, sold at local venues in Calafell and El Vendrell.
