24-Nov-2015 -- We arrived in Sênmônoŭrôm (eastern Cambodia) on 23 November 2015. In our Guesthouse we found a map of Cambodia with details around our confluence. So we saw a small village called Srê Trav which should be near by the confluence.
Next day we started from Sênmônoŭrôm at 9 am to Kaôh Nhêk by mini bus. Kaôh Nhêk is on the half way to Ban Lŭng. There we found a guesthouse ($8 one night) where we left our big luggage. The owner of the guesthouse spoke a little bit English. So we explained to him that we would see a place near the village Sre Trav and he helped us to rent a motorbike with a driver.
With this information and a GPS device we drove on a dirt road to Srê Trav. About 1000 meters from the confluence the road took another way. But we found a small forest trail which led us near to the confluence. For the last 150 meters we needed a stick because the grass was almost one and a half meter.
