Live NPS alert for Zion National ParkAbout 3h 20m of moving time for 9.4 mi and 334 ft of climbing — that is Naismith's planning rule, so it counts walking only, with nothing for photos, lunch or the queue at the top.
Planning figures for that much moving time are 1.7–3.3 L, cool day to hot. No refill point is recorded on the route, so you carry all of it. Informational only, not medical advice.
No — The Narrows (Bottom-Up) is closed to dogs. Our Zion National Park dog guide lists the trails where they are welcome, plus boarding and the nearest 24/7 vet.
We rate it comfortable from age 8. It is not a stroller route. That rating is our own hand-check of length, footing and exposure, not an official NPS grade.
About 40% of the route is shaded, and Zion National Park peaks around 100°F in its hottest month. The less shade a route has, the more of it you want behind you before midday.
