What to pack
Pack layers, even in summer, as the weather can change quickly. A waterproof jacket and comfortable walking shoes are essential, as you'll likely be doing a lot of walking and encountering rain. An umbrella is also useful. While there are no specific cultural dress codes, dressing respectfully when visiting religious sites is always appreciated.
