If you're looking to take a helicopter tour to Grand Canyon. I highly recommend Maverick Aviation. I have taken a few of their tours before, other than getting motion sickness from the ride, I have been quite pleased with them. Their Wind Dancer tour takes you to the west rim of Grand Canyon, fly pass the skywalk bridge, and descends at the bottom of the canyon/near the Colorado river. They also provide light snack and champagne when you land. However my favorite tour will have to be the Canyon Dream tour. It is a 6-hour tour and you depart from the Henderson Executive airport. You take a 40-min flight (on a private/20-seat plane) to the Grand Canyon airport, where you hop onto the helicopter and they take you INTO the South Rim of Grand Canyon. After the helicopter ride, they will give you a chance walk around the national park (with lunch provided) to explore around the rim.
