Minivan to the NamPhaPaYai camp have been moved to Mo Chit Bus Station since this month. THERE IS NO MINIVAN GOING FROM VICTORY MONUMENT TO KAENG KHOI (CAMP'S TOWN) ANY MORE!!!
The nest way to go Kaeng Khoi by public transport is going by minivan, departing from Mo Chit bus station every hour. But when you arrive Kaeng Khoi, you may still need to take a taxi to the camp, which cost you 400 THB for a ride (no matter how many people) .
