Isaac Peak is a 6,726-foot (2,050 m) rock formation in Zion National Park in Washington County, Utah, United States.

Access to Isaac Peak is from the main Park road through Sand Beach Trail.

Explorer Frederick Samuel Dellenbaugh, a companion to Powell's, illustrated and wrote about the park in Scribner's Magazine, giving publicity to the region.

[11] Sands of Time is located starting on a prominent crack to the left of Tricks of the Trade (VI class 5.10 A3).

The route climbs the south face of the main buttress although it doesn't complete at the summit.
