If you are planning a trip in winter, be sure to take a warm jacket, hat, and gloves, as the temperature often hovers around zero or drops lower. Spring and autumn can be quite cool and windy, especially in March and November, so a windproof jacket and a cosy sweater will be indispensable. Do not forget a compact umbrella or raincoat: rains happen here regularly, especially in late spring and early summer.

For this time of year, light clothing made of natural breathable fabrics, as well as sunglasses and cream for protection from the active sun, are ideal. Nevertheless, even in summer, evenings can bring freshness, so a light cardigan or hoodie in your luggage will certainly not be superfluous for long evening walks.
