Hiking preparation checklist for Spain:
• Hiking boots with non-slip soles (Vibram or similar), tested before the trip, with thick hiking socks.
• Walking poles (Trekking poles), which ease the pressure on the knees on descents.
• Water: at least 1.5–2 litres per person, and more in summer; do not count on finding springs.
• A hat with a brim, sunglasses and sunscreen SPF 50.
• Layering: an inner layer that wicks sweat, + wool or fleece, + a jacket that protects against wind and rain.
• A headlamp (Headlamp), even on day trips.
• First-aid kit: blister plasters (Compeed), antiseptic, painkillers, allergy medicines, elastic bandage.
• Offline map: Wikiloc (the most used in Spain), Maps.me or AllTrails, with the route downloaded in advance.
• A portable charger (Power bank) and a cable.
• Snacks: nuts, dates, energy bars, fruit.
• For children: properly fitting shoes that are not new, an extra layer, a hat, a whistle the child wears, favourite foods, and a short circular route (under 8 km) with rest points; a carrier for babies.
• In summer: start before 9 am, avoid walking between 12 noon and 6 pm, and follow the heat alerts (AEMET); some trails close during heatwaves or because of fire risk.
• In the mountains (the Pyrenees, Picos de Europa, Sierra Nevada): the weather changes quickly; carry a rain jacket, turn back immediately in dense fog or thunderstorms, and remember that the temperature drops by about 6 degrees every 1000 metres.
Trail markings:
• GR (red and white): long trails of more than 50 km that run for several days.
• PR (yellow and white): shorter trails of 10 to 50 km, suited to one day.
• SL (green and white): local trails under 10 km, best for families and children.
• Two parallel lines = keep going; a mark shaped like the letter L = turn; an X mark = wrong way.
Emergencies:
• The single emergency number in Spain and Europe is 112; it works free of charge and without credit.
• Download the My112 app (or a regional app such as 112 Andalucía / SOS Madrid); it automatically sends your location to the rescue teams.
• Tell someone your route and your expected return time before setting off.
