On this trip to South East Asia my goal was to see the Angkor Wat ruins. I was disappointed but the journey from Siem Reap on a old crowded metal boat was worth it. Yes it was hot and humid but this is Asia.
The journey took six and half hours during the wet season and I have read it could take up to 12 hours during the dry season. Good luck if you took the boat during the dry season. Only adventurous people make the journey by boat once. Crazy people will do it more than once. 🙂
