Photographs show different viewpoints, dates and conditions. They do not establish current access to a particular route. Every image is credited below.
At Angkor, scale is only the beginning. Moving from an approach to a gallery and then an enclosed court changes what you can see and how the building feels. Reliefs reward a much slower pace than a circuit of viewpoints. Compare one carefully studied passage with the larger composition, then take the same approach to a contrasting temple.
Choose a manageable group of temples instead of treating every available circuit as compulsory. Leave a shaded break between concentrated visits.
