Petroglyph Canyon is located near the center of the Valley of Fire.
The canyon is about .75 miles long and ends at the "Mouse's Tank".

Petroglyph Canyon is probably the Valley of Fire’s most popular attraction, carrying as it does the park’s largest concentration of petroglyphs – primarily symbols incised by prehistoric Native Americans from the Lost City. The purpose of the petroglyphs is unclear: some may have been no more than the road signs of their day, while others might have had a religious or mystical significance.
