This remarkable cleft in the east end of the Sweetwater Rocks drew diary comments from many pioneers. Many walked and waded in the Sweetwater River through the gorge while their wagons followed the trail through the pass to the east, a route now followed by an access road to the historic Sun Ranch. A BLM interpretive site is located just south of the Gate giving details of the long and colorful history of the area. The hard-surfaced interpretive trail is ADA accessible. There are restrooms and trash collection.
