The Costa del Sol is having one of its strongest runs in living memory. In the summer of 2025 alone, the region welcomed 6.2 million tourists, generating an economic impact of €8.915 billion and a 3% rise in tourism employment, breaking all previous records. Property investment is following the same trend, and the region has firmly established itself as the economic engine of Andalusia.
But this success raises a question that not enough people are asking: is there actually a strategy in place to manage all this growth sustainably over the long term?
There is a real difference between attracting visitors and being equipped to handle them. The Costa del Sol has been doing the first part well for years, and the numbers bear that out. The second part is a conversation the sector can no longer avoid.
Sustained tourism growth puts pressure on infrastructure, public services and natural resources. The A-7 comes to a standstill every summer. Water supply struggles to keep up with seasonal demand. And house prices are rising at a pace that creates opportunities for investors while making access harder for local residents. These are not abstract concerns: they are clear signs that growth has outpaced planning, and that a coherent territorial strategy has become a necessity rather than a nice-to-have.
Yes, strategies exist. At a national level, the Sustainable Tourism Strategy 2030 sets a clear direction: shift away from the traditional sun-and-beach model towards one built on quality, sustainability and a fairer distribution of tourism’s benefits. At a regional level, plans like the Costa del Sol Action Plan 2026 translate those principles into a concrete technical roadmap.
From our perspective at Terra Meridiana, both strategies are pushing in the same direction: prioritising three high-value segments that put less strain on the territory:
That said, the success of all three depends on something no marketing strategy can replace: solid urban planning that ensures the territory can actually absorb this level of growth. The issue is not the absence of plans. It is the gap between what gets designed and what gets built. That is where the POU comes in.
For property investors, the answer to unmanaged growth lies in technical planning. The Urban Development Plan, known in Spain as the POU, is the instrument that helps protect an asset from losing value because its surroundings have deteriorated. It matters for three reasons:
Projects like the Senda Litoral coastal path and the Corredor Verde del Guadalhorce show that tourism growth and better infrastructure can go hand in hand, as long as the planning is serious and the coordination is real.
The most pressing issues facing this territory do not stop at administrative borders. A visitor staying in Estepona will often spend their day in Marbella or Benahavís, but the management of key infrastructure stops at each municipal boundary. The A-7 passes through several local authorities with no coordinated transport policy to ease congestion. Water is managed in a fragmented way. And a facility needed on the border between two municipalities can sit unresolved indefinitely because neither side can reach an agreement.
For investors, this fragmentation has real consequences: planning decisions in one municipality can affect asset values in the neighbouring one, with no mechanism to anticipate or address that. The challenge is to move towards genuine coordination between local authorities, built around a shared vision for the territory that outlasts individual electoral cycles.
The case for proper planning is not just theoretical. This year marks the twentieth anniversary of Operación Malaya, Spain’s largest ever urban planning corruption scandal, which ended with the unprecedented dissolution of Marbella’s town hall by central government. It showed, in very concrete terms, what happens when planning decisions serve private interests rather than the public good, and how long it can take a city to recover its reputation.
It was not a one-off. Operación Yedra in Churriana uncovered illegal earthworks in protected areas carried out with complete impunity. This region has learned those lessons the hard way, which is why technical rigour and administrative transparency are now non-negotiable in any serious conversation about land use and development.
The Costa del Sol does not need to slow down. It needs to grow more intelligently. The good news is that the tools are there: solid urban planning frameworks, infrastructure investment that anticipates demand, and a growing willingness among local authorities to coordinate. The region has everything it needs to take that next step, and there are increasing signs that it is doing so.
For investors with a long-term outlook, that process of maturation is part of what makes this market compelling. A Costa del Sol that learns from its past, plans its future carefully and continues to attract international capital is a destination with real foundations for the years ahead.
