I've seen some pretty spectacular photos from HKG, particularly on approach to 07R, which is closest to Lantau Island.
Some examples:

I'd love to have the opportunity to get here and I've looked at how best to do it; there is a site which explains how to reach some of the locations for spotting, but the access to the island seems quite difficult and includes a very short "ferry" journey to the Sha Lo Wan public pier.
Has anyone done this? Alternatively, is it possible to get to the photo locations by taking a taxi from Tung Chung?
