As stated on their website, "Authentically fashioned after a traditional Mexican village, Tlaquepaque, meaning the 'best of everything,' has been a Sedona landmark since the 1970s.

It takes about 2-2.5 hours to drive from Sedona to the Grand Canyon. Be prepared that the beginning of the drive has some winding roads between the cliffs of Sedona (experienced drivers recommended). The rest of the trip is quite flat and on major highways. Also, you will want to aim for the South Rim, as the North Rim is a much longer drive.
