The Royal Palace as seen from the other side of the river. Summertime is, when the evening skies are clear and balmy, the perfect time for an evening cruise along the Tonle Bassac river. One can rent an entire boat, similar to this one, for $8-10 an hour. You can bring as many friends as you like and all the food and booze you desire. For additional amount (and depending on the number of guests and the variety of food and drinks required) the boat-owners can also provide catering.
