You may be referring to the Observation Point hike at Zion. It starts off with a 2k ft high switchback route. But at the end it will put you smack dab in the middle of the canyon higher than Angeles Landing (and a bit safer, less crowded hike). And you still have a stunning view of the canyon and far beyond.

I did Angel's Landing at one point and I'm glad I did but wouldn't do again. Observation point is my favorite but I don't think my old route is open any longer though you can still apparently get up there by another trail.
