Everything east of Marbella town, from Río Real out to the Mijas boundary: roughly four to fourteen kilometres from the centre, either side of the A-7.
Not one place but the municipality's whole eastern half, and the reason people quote wildly different Marbella prices at each other. It holds Los Monteros and Río Real at the town end, Las Chapas and Elviria in the middle, Cabopino and Artola at the far edge by the dunes. Plots get bigger and prices get lower the further east you go, which is the entire trade being made out here. Beachside pockets like Marbesa and Costabella sit on the sand; the hillside stretches behind the motorway sell the view back down over it.

Counted from 112 distinct homes asking €3,000,000 or more, deduplicated across the agencies listing them, 20 of which are on the market with more than one firm at once. 74 of the 112 come from a source that dates its listings individually; the rest publish one timestamp for the whole catalogue, so their prices are current but their edit dates are not evidence. Every figure is the agency's own asking price, linked above.
Numbers from the linked sources, dated as marked. Asking is not getting, for what sellers actually achieve, the catalogue keeps receipts.
