Bureau Of Land Management, Wyoming.
The Castle Gardens Petroglyph Site is located in central Wyoming approximately 45 miles east of Riverton.
The name of the area comes from the outcropping of sandstone which the wind has eroded into fanciful shapes resembling the turrets and towers of castle. This unusual formation has been luring visitors for thousands of years, and many of them left their mark in the soft sandstone--the area holds a treasure of Native American rock art, or petroglyphs.
Improvements to the site have been made over the past several years to enhance the experience and to better protect the petroglyphs. A fine crushed gravel walking trail exist throughout the site, foot bridges to ease the crossing of deep drainages and a new parking area.
Future work at Castle Gardens will include new interpretive panels and benches for enjoying the view. All of these improvements are designed to reduce the amount of vandalism through increased understanding of the site and better visitor facilities.
The road is somewhat rough most of the year, especially the county road section of the Casper route, so high-clearance, four-wheel-drive vehicles are recommended.
We will be upgrading the Recreation.gov Help Center system this weekend. From 11:00pm ET on 10/24 until 10:00am ET on 10/25, the Help Center, phone support, Contact Us page, and chat support may be temporarily unavailable.
