For a trip between June and August, T-shirts, light trousers, and shorts are suitable, but be sure to bring a hoodie or sweater for cool evenings.

A universal tip for travelers is to follow the principle of layering. This allows you to easily adapt to temperature changes by simply adding or removing a layer. Also, don't forget comfortable, broken-in shoes for long walks, as the terrain is perfect for hiking trails. In the summer months, despite the moderate heat, the sun can be quite strong, so sunscreen and a hat will be very useful.
