The journey takes 90 minutes half of the time on the bumpy dirt road. We hired a driver and were stunned by his asking price (we didn’t ask for the price in advance - it was our fault - but still...) plus $20 per person outside the ticket. The sleeping Buddha and the waterfall were not that magical. The waterfall was destroyed by a lot of garbage - considering there are plenty around Siem Reap Other places to play, and it shouldn't be on my short-haul or long-haul schedule.
