Dramatic. Green. The desert after the rain.
Late summer. Still hot but the monsoon brings green, the desert flushes with life after storms. Slightly less crowded than July as families head home for school. Dramatic skies.
Magic window: Dark Sky Season (Jun – Sep nights)
The longest, warmest nights of the year, warm enough to sit outside at midnight. The Milky Way arcs directly overhead. Zion is a certified Dark Sky Park, pair with Bryce Canyon’s Bortle 2 skies for the full experience.
