You should save a day to do this tour. This combines 2 of the trip in 1. The trip was well spread and leisurely planned. 1st we go to Cu Chi Tunnels, wear comfortable walking shoes, they stop at the handicap painting market, the products are sold 5 times higher, dont buy as you will find the same product in this trip at Cu chi tunnels souvenirs shop. The guide is knowledgeable and explains everything while walking through the area. Next we had a well spread set menu for lunch. At Mekong Delta we have fruits at a family farm, coconut candy farm where they show you how they are made and sell their products, bee farm where they sell their products, 20mins boat ride through the coconut village, free coconut once returning in the boat back to mainland. Cu Chi is 1.5 hours north of HCM district 1 and Mekong is 1.5 hours south of HCM. So expect some long traveling in between. Carry Vietnamese dong as you will be asked to tip at some places and if you buy from the farms, they only accept cash.
