I’m planning a road trip that mixes the best of Arizona’s national parks with a quick stop in Southern California. The idea is to spend about 5–6 days exploring Arizona — think Sedona’s red rocks, the Grand Canyon, and Monument Valley — and then head west for 2 days in San Diego to relax by the coast. We’d rent a car, so I’ll need someone comfortable driving, but it should be a fun mix of desert adventure and coastal downtime.
