During the peak heat of mid-summer, some European destinations get a bit scorched (especially along the Mediterranean and on the Iberian Peninsula). However, in higher altitude regions (and colder, more northern countries), the weather is simply sublime. From Iceland’s national parks to the highland meadows of the Mont Blanc Circuit, you can experience ideal conditions in many regions. Plus, it’s the best time to visit the United Kingdom as well.
In North America, national parks with limited seasons, such as Glacier, enjoy their best months.
