For walkers planning a trip to Spain to come walking and hiking with me, I strongly advise that you purchase the appropriate holiday/travel insurance to cover you against accidents, cancellations, flight disruptions, etc. associated with your travelling plans and holiday arrangements.
Similarly, I highly recommend suitable hillwalking insurance for the duration of your trip to adequately cover you when you are out walking and hiking, if this is not already included in your travel insurance. Importantly, it is not sufficient alone to rely on your European Health Insurance Card (EHIC) for health cover and treatment while on holiday, especially if any treatment that will be required is for a walking/hiking related injury. Please note that EHIC does not replace basic travel insurance; neither does it replace, nor is it a substitute or replacement for adequate hillwalking insurance.
Please refer to the relevant links below for information on acquiring a European Health Card or appropriate hill walking insurance depending on your country of origin:
