The Golden Mile (Milla de Oro) is the stretch of Marbella between the western edge of town and Puerto Banús. Depending on where its ends are drawn, it runs for about 4 to 6.4 km. The old N-340, now the Bulevar Príncipe Alfonso de Hohenlohe, cuts it in two. Its story starts in 1954, when Prince Alfonso of Hohenlohe turned the Finca Santa Margarita into the Marbella Club. The Puente Romano apartments followed in 1974 and became a hotel in 1979. From the mid-1970s King Fahd of Saudi Arabia (then crown prince) had the Mar-Mar palace built here, and the King Abdul Aziz mosque was finished in 1981.
Daily life splits along the boulevard. On the sea side are the hotels, low-rise apartment complexes and beachfront villas, and a seafront path runs past the Marbella Club pier. Inland, the land climbs through Nagüeles, Las Lomas del Marbella Club, Altos Reales, Sierra Blanca and Cascada de Camoján towards La Concha (1,215 m). Up there almost every errand needs a car. Groceries come from the Lidl, ALDI and Supersol on the A-7 service roads. Marbella's old town is about 8 minutes' drive east and Puerto Banús 6 minutes west, and urban buses run along the boulevard between them.
There is no separate census for the Golden Mile: the municipality of Marbella had 159,786 registered residents on 1 January 2025, and the town's population rises by about 30% in summer. The Golden Mile suits families who want Swans International School (its secondary campus is in Nagüeles) and Blue Flag beaches: Nagüeles and Casablanca held the flag in 2025 and again in 2026. It also suits buyers who want a hotel-resort life of tennis, beach clubs and restaurants within walking distance, rather than village life.
July and August are the busy months. The Starlite festival fills the Cantera de Nagüeles quarry with concerts through the summer. Puente Romano's beach runs Suite del Mar nights on Thursdays, and daybeds at the beach clubs need booking. Much keeps going in winter: the Marbella Club says its beach restaurant opens all year, Victor's Beach says it opens all year, and Puente Romano describes La Plaza as a year-round cocktail and dining scene. January is much quieter on the beaches.
The downsides are real. The boulevard is a busy multi-lane road, and its traffic and noise reach the first rows of homes. Hillside streets have few pavements. The Golden Mile itself has no cheap tapas bars, no municipal sports hall, no hospital and no golf course, so for those you drive into town or to Nueva Andalucía. It is also Marbella's most expensive district: The portals' index puts it at €5,626/m² in October 2026, against €5,060/m² for the municipality as a whole. The cheaper way in is an older flat in Nagüeles Alto or La Carolina, from about €250,000–400,000.
