Trail Overview

This sandy single wide track with a few turnouts for passing is the Southern route to access the Cosmic Ashtray. 4x4 is highly recommended. The Ashtray is approx. 4.3 miles past the trailhead at Harris Wash so the length of your hike will depend on how far up Harris Wash Road you go. The last half mile section is very deep sand, but is less than a mile hike to the Cosmic Ashtray. There are a few washes to pass through, and is highly recommended to not pass if there is rain in the forecast at all. There are no trail signs to find the Ashtray, and no service out here, so be prepared with GPS coordinates and an offline map. Take plenty of water and gas as there are no service stations within 30 miles, and no shade on the hike. It is possible to climb into the bowl, but you'll need to bring rope to repel down and get back out. Please stay on the designated roads and always pack in what you pack out.
