Health
Spain has high food and water standards; tap water is generally potable in cities and resorts, though hikers should treat untreated water. Summer heat, strong sun, wildfire smoke, beach currents and mountain weather are practical risks. Use insect precautions outdoors: CDC notes bug bites can spread disease in Spain, including sand-fly leishmaniasis risk. Higher routes in the Pyrenees/Sierra Nevada require sun, cold and altitude planning.
Vaccinations
Consult a doctor or travel clinic at least a month before travel. CDC advises being up to date on routine vaccines, including MMR, flu, polio, varicella, Tdap and shingles as applicable, and COVID-19. Hepatitis A is considered for most travelers, especially rural areas or street food; hepatitis B is recommended for unvaccinated travelers under 60 and may be considered for older travelers. Rabies pre-exposure vaccine is only for selected higher-risk activities or access concerns. Yellow fever vaccine is not recommended and not required for entry to Spain.
eSIM / connectivity
eSIM is widely usable in Spain if your phone is unlocked and eSIM-compatible. Major local networks include Movistar, Orange/MasOrange, Vodafone Spain and Yoigo; Movistar states eSIM is available for mobile lines and compatible with prepaid when requested in store. Orange Travel sells Spain eSIM plans online/app and lists partner coverage on Orange, Movistar/Telefónica, Vodafone and Yoigo. Airport, city-store physical SIMs and travel eSIM marketplaces are also common.
