You need a permit to hike the Narrow. There are hiking stick (just some tree branch) provided at the start of the trail, but you can buy your own if you plan to hike else where in future.
The narrow is currently close due to heavy water flowing so check before you go. The permit is available for reservation at the 5th of each month.
Here is the site for more info and reservation: https://zionpermits.nps.gov/wilderness.cfm?TripTypeID=3
If you cannot get permit, then I recommend to take The River Walk Trail (2miles, paved, easy). The River Walk is first part of the Narrow, it always opens and no permit required. You can get 80% of the Narrow. The trail ends where the Narrow starts.
The extra time, you can take Emerald Pool trail, it's beautiful, you can see waterfalls. Be sure to climb up top.
ST chưa hike cái Angel Landing nên không biết, nhưng nghe nói đẹp, và ko cần permit.

Ổng là thợ chụp hình chuyên nghiệp, nên tất cả các trail ổng đều chụp tường tận, vô coi có thể thấy nó đẹp xấu ra sao, rồi chọn cho thích hợp. Very detail with lots of photos.
