The Department of the Interior announced that Secretary Bernhardt met with His Royal Majesty King Charles III to designate the Shenandoah Valley as a "sister park" to Scotland's Highlands and to similar mountain areas in Ireland and Wales. The department presented the designation as a cultural and conservation partnership in its weekly "Inside Interior" update.
The "Inside Interior" update said the meeting was held to "spotlight one of America's Crown Jewels, the Shenandoah Valley," presenting the move as an effort to strengthen international ties around shared landscapes. The department did not provide further details in the segment on any changes to park boundaries, joint management arrangements, or funding connected to the designation. The announcement was presented as part of a series of department highlights released in the same update.
