1. Start with the youngest hiker.
Pick distance, elevation and footing for the person with the least margin.
2. Check heat before difficulty.
An easy exposed trail can become a bad choice in dangerous temperatures.
3. Know the bathroom plan.
Trail logistics matter more with children than glossy travel pages like to admit.
4. Set a turnaround rule.
Decide when you will turn back before tired brains start negotiating.
5. Carry more water than optimism.
Arizona rewards preparation and punishes wishful thinking with impressive efficiency.
6. Have a backup.
Weather, parking, closures and kid energy can change the plan. Keep a shorter option ready.
