200+ feet underground on Route 66?! 🤯🛣️ Day 3 took us to Peach Springs, where we explored grandcanyoncavern and even had lunch underground. Definitely one of the most unique experiences we’ve had in Arizona. Then it was off to Seligman for all the vintage signs, classic cars, quirky shops, and old-school Route 66 charm before ending the night in Williams at the gcrailway Hotel. 🚘🚂 Follow welcometoarizona for Day 4, and find our Arizona Route 66 itinerary at the link in bio! 🗺️ #ArizonaRoute66 #Route66RoadTrip #carsmovie #ArizonaTravel #WelcomeToArizona
