“A beginner trail near the McCabe entrance.
— Adam Kagy
Sandy Wash Trail is far away from the main trail system. It's a beginner trail and this area is frequented by quite a few folks who shoot guns, sometimes across this trail! Taking this into account this is the big reason why this trail doesn't get used very often and when it does it's usually by moto bikes.
The name is self explanatory as it partially follows a sandy wash near the McCabe Parking area.
