Ash Meadows National Wildlife Refuge
Here is the Refuge website. Brochure Map
“Year-round hiking is permitted along designated refuge roads and trails. Refuge boardwalks provide an up-close view of the springs, fish, and plants of Ash Meadows without disturbing the fragile habitat.”
? The photos of the boardwalks look as if they are wheelchair accessible, but you had better call 775 372-5435 to be sure.
