The Cu Chi tunnels tour was great- this is my second time doing this tour (previously doing it with a different company some years ago) This tour was much better- the guide was funny and well informed. He was very passionate to teach tourists his side of the story. Expect to spend a while in the van/bus as the drive is long, and traffic can be terrible in HCMC. That's not the tour's fault tho, and all of these tours will have this "issue". You can buy light refreshments and drinks at the Cu Chi tunnels at reasonable prices too if you need.

Tuan was extremely knowledgable as he himself fought in the war and also very funny. The tour was very interesting and definitely a must if you’re in Ho Chi Minh. The only downside was that there was no opportunity to eat lunch or buy food so make sure you take plenty of snacks and water.

The tour picked me up on time and our guide was good. They don't provide enough water though, only 0.5 liters for the whole 6 hours. I felt they could have provided more background information on the war. The tunnels are quite far away so half the time is spent getting there and back from HCMC.
