For as long as I can remember I've wanted to visit the Grand Canyon. I don't understand why I waited so long to actually do so. In 2007 I booked a helicopter tour from Las Vegas to the West rim of the Grand Canyon. What's interesting about the approach by helicopter is that you descend about 1 km to the canyon floor and in so doing you get a good idea of how high the canyon walls are. In 2014 I stayed two days at the South rim, from where I hiked part of the South Kaibab trail and the Grandview trail. I'd love to do a rim to rim hike some day.
