The destination will welcome its first guests in Spring 2022 and pre-registration is now open.
The new resort is a 20-minute walk from Marbella’s city centre and a one-hour drive from Gibraltar, Ronda, and Malaga, or two hours from Granada, Seville, and Cadiz.
The resort will offer 14 hectares of garden, five swimming pools, a family waterpark, an adult-only "zen zone", two restaurants, a "gourmet lounge" and three bars.
Estelle Giraudeau, managing director of Club Med UK and Northern Europe, said the brand is "looking forward" to returning to the country after more than 20 years away.
"The resort offers the perfect blend of luxury, experiences, and cultural adventures for both families and couples alike," she added.
Club Med’s upcoming sale will go live from 12 to 14 October, offering 15% off of all resorts, including Magna Marbella, for holidays booked up until October 2022.
