Arriving Oct. 4th for Balloon Fiesta in Albuquerque. Have three days planned there. Then comes the dilemma...which way to head from there? Either northeast to Santa Fe and Taos or west to Flagstaff and up to Grand Canyon. We have 11 days and don't want to feel worn out on our return home. As we usually try to pack in so many miles that we are exhausted on our return. We've quit calling them vacations and started calling them "sight-seeing trips." Can we make the big loop from Flagstaff up to Grand Canyon through Monument Valley and 4 corners and back through Taos and Santa Fe within that time frame and not feel drained? Or is that just too much? If you think so, any suggestions for "must-see" sights in Northern NM would be appreciated. If we just stick to NM, what should be see. We like everything so any thoughts or insights would be appreciated.
