All participants are expected to arrive with appropriate health insurance according to their needs, particularly those wishing to practice winter sports. National cards other than Spain's are generally not accepted, but the European Health Insurance Card which extends your national coverage of a EU member state is accepted in the public system. The organization takes no responsibility.
The major public Hospital is here.
