If you've never been to Vietnam or Saigon, and you're arriving for the first time by plane, try and get close to a window. The view is really wonderful; the sun glinting from a thousand roofs, the buildings all painted in pleasing pastels such as creams, pinks and light blues. There is no uniformity to the skyline as tall narrow buildings shadow small ones, it looks like a just begun lego kit.
Here's a shot looking down on the heart of D1. You can see the town hall on the right, and in front of that is the Rex Hotel (green covers on the roof). In the distance, you can see how many trees there are in parts of D1.
This is slightly elevated from the last picture, looking out over D1 and D3. You can see the famous Saigon landmark, The New World Hotel, the big yellow building top left.
