Mountain roads can be unpredictable, so planning is key. Start by researching scenic locations, gas stations, and rest areas. Use apps like Google Maps to mark potential stops, and if you’re entering remote areas, download offline maps. Consider how much driving you can comfortably manage in a day and plan rest stops accordingly. Flexibility is important, so allow extra time for detours, photo ops, or breaks. Ensure you have access to supplies like food, water, and a place to rest, particularly in isolated areas.
