Start at Sunset Point. Hike north (left) along the canyon rim until you reach Sunrise Point. From there follow the Queens Garden Trail to a 4-way intersection down at the bottom of the canyon. Continue straight ahead into the Wall Street half of the Navajo Loop which will return you back up to Sunset Point. Alternatively you can hike down Wall Street and up Queens Garden but doing so is not as scenic or safe and therefore not recommended by the staff of Bryce Canyon.
