As Zion gets more popular, use strategies for getting the experience you came for by following these tips:
Timing: Even in busy June, I found Zion delightful in the cool mornings between 7 and 10 a.m. It also was nice after around 4 p.m., when a lot of day visitors left and the late day sun turned everything rosy gold. Come early or late, and you also miss the midday heat.
Days and seasons: Come midweek, not weekends. Come on a regular day, not a holiday or holiday weekend. Come in April or October, the shoulder seasons, rather than in busy July and August. Zion is open all winter (it does get some snow and ice), but you can drive your car rather than take the shuttle then.
Trails: Don’t shun easy trails such as Emerald Pools and Riverside Walk just because they’re popular. Both are extremely beautiful, even when you are surrounded by other tourists. More challenging trails such as Angel’s Landing or the Narrows require proper gear and preparation; don’t just set off on your own in flip-flops.
