4. Trail Map: Bring a detailed trail map or a GPS device to ensure you stay on course. The trail is well-marked, but it’s always wise to have a backup navigation tool if you decide to explore and hit some other trails off of the Tom’s Thumb trail.

6. Proper Clothing: Dress in lightweight, moisture-wicking layers for comfort in the fluctuating desert temperatures.
