Preah Khan temple is one of the larger temples in the Angkor complex. It is similar in style to the mysterious tree-covered Ta Prohm temple, however Preah Khan has been under more restoration and maintenance. Still, it is a beautiful temple with large trees strewn about. I loved the atmosphere here.
