Prepare for hot summer days. Bring plenty of water and wear a hat and sunscreen. Use extreme caution with fire. Open fires are permitted only in established fire rings at designated campsites. Never enter a flooded wash.
Dry washes can become fast moving rivers after rains.
Dirt roads become impassable after rains. Expect late afternoon storms July-August. Africanized bees are present in southern Arizona. Stay away from active bees. Backcountry bikers and drivers should carry spare equipment and be prepared to make their own emergency repairs.
