Wall Street and the Rim Trail from Bryce Point to Inspiration Point have closed for the winter season. All other front country trails remain open. Fairyland Point Road and Paria View Roads have closed to allow for skiing and other winter activities.
The description of Queens Garden & Navajo Combination says:
... Continue straight ahead into the Wall Street half of the Navajo Loop which will return you back up to Sunset Point ...
Does the closure of Wall Street mean that one cannot hike Queens Garden & Navajo Combination?
