If you own land, operate farms or run businesses in the Guadarrama Sierra area, this regulation affects you right now, even though the final expansion has not yet been approved. The Council of Ministers approved on March 31, 2026 the initial proposal for the expansion of Guadarrama National Park, published through the Resolution of April 13, 2026 from the Autonomous Body National Parks.
This initial approval is not the end of the process: it is the beginning of the administrative procedure that may culminate in the final expansion. And it is precisely now when businesses, landowners and municipalities have the opportunity to participate and submit objections.
What does this regulation establish?
The resolution publishes the agreement of the Council of Ministers approving the initial proposal for expansion of Guadarrama National Park. This initial approval has two immediate effects:
- Opens the consultation period and prior administrative procedures for the final expansion.
- Requires affected municipalities in Madrid and Castilla y León to participate in the public information process.
If the expansion is finally approved, the incorporated areas would be subject to the special protection regime of national parks. This regime implies restrictions on use and activity in the affected territory, with direct impact on agricultural, livestock, forestry and tourism activities.
The exact list of affected municipalities and land must be consulted in the complete proceedings published by the Autonomous Body National Parks, as the resolution does not detail the specific geographic limits of the expansion.
Economic and operational impact
The expansion of a national park's perimeter is not a minor change. The special protection regime that applies to these spaces can translate into very concrete economic and operational consequences for those operating in the area:
- Agricultural and livestock activities: Possible limitations or prohibitions of certain practices in the incorporated areas, with need to adapt exploitation plans.
- Forestry activities: Restrictions on timber harvesting, forest management and forestry land uses.
- Tourism companies: Changes in permits required for active tourism activities, rural accommodations and services in the park's surroundings. In some cases, the expansion may represent an opportunity for positioning as a protected nature destination; in others, it may limit the capacity to develop new infrastructure.
- Landowners: Land incorporated into the park becomes subject to the restrictions of the special regime, which may affect the value, use and transfer of properties.
In this initial phase, the concrete economic impact will depend on the outcome of the objection process and the final limits that are established. Acting now in the proceedings is the only way to influence that outcome.
Who does it affect?
- Landowners adjacent to Guadarrama National Park who may be incorporated in the expansion.
- Farmers and livestock farmers with operations in the park's area of influence, in municipalities of Madrid and Castilla y León.
- Forestry sector companies with operations in the Guadarrama Sierra area.
- Tourism companies: rural hotels, active tourism companies, mountain guides and operators developing activities in the sierra.
- Municipalities in Madrid and Castilla y León affected by the expansion, which have an obligation to participate in the public information process.
- Legal advisors and consultants managing interests of clients with assets or activities in the area.
Practical example
An active tourism company operating hiking routes and mountain activities in the Guadarrama Sierra area currently has its permits in order under current regulations. If the park expansion incorporates the areas where it develops its activity, that company would begin operating within the special protection perimeter.
This could imply the need to obtain new authorizations, adapt its routes to park restrictions or limit the number of participants per activity. If the company does not submit objections during the public information period, it will lose the opportunity to convey to the proceedings its specific situation and the possible economic damages the expansion would generate.
The same reasoning applies to a livestock farmer with pastures in the area or a forest owner with ongoing operations: the objection window is the key moment to defend their interests.
What should businesses do now?
- Identify if your land or activities are in the area of influence. Consult the complete proceedings published by the Autonomous Body National Parks to determine if your assets or activities fall within the perimeter of the proposed expansion.
- Review the concrete impact on your activity. Analyze what restrictions of the special protection regime of national parks would affect your operation, business or land if the expansion is finally approved.
- Submit objections within the deadline. The public information period is the only formal way to convey to the proceedings your interests, objections or proposals for modification. Those who do not object within the deadline lose that right.
- Coordinate with the corresponding municipality. Affected municipalities in Madrid and Castilla y León have an obligation to participate in the process. Contact your town hall to learn about planned actions and add your position to the municipality's if appropriate.
- Seek legal advice. If you have relevant assets in the area, it is advisable to have specialized legal advice in environmental and administrative law to prepare objections with the greatest possible strength.
- Monitor the proceedings. Initial approval is only the first step. Follow the development of the proceedings in the BOE and on the Autonomous Body National Parks website to not miss any relevant procedure.
Frequently asked questions
