Death Valley is very safe in every way other than heat exhaustion/dehydration. I did 6 nights there earlier this year doing most the 4x4 trails, back country camping and hiking 100% alone. Not once at all did I ever feel unsafe. The biggest knife I had on me too was a kitchen paring knife to make dinner with.Very nice. I always wonder, I've yet to venture out in that area alone. I want to go with some buddies so we have multiple cars. Do you guys pack weapons? Guns to be specific, to be safe?
