I might have some downtime in between a trip to SEA. I was wondering if someone has done, or heard of someone one taking a few days to go down the Mekong River ? Plan B, I want to take a sampan to Catba National Park ? Basic criteria is a) No cell signal b) No creature comforts c) Just a short wave radio. to chill for a week before heading back to SIN. I wonder if there was anything comparable to the mail boats from Manaus to Santarem ?
