Ciudad Madero has a beach named "Playa Miramar", which, in recent years, has been expanding its services with new hotels and restaurants. Near the beach there is a lighthouse, named "Faro de Ciudad Madero" – although this has been replaced by a red beacon light atop a small tower, to guide approaching ships in to the channel of the Río Pánuco. However, in October 2006, the Ciudad Madero Planning Commission signaled its intention to build a new lighthouse because of the cultural and tourist values it would provide.
