We booked two tours via Tiger tours and they were both great days out. The first was to the Black Mountain and onto Cu Chi tunnels. Chau, our guide, was extremely informative everywhere we went and gave us plenty of opportunities to take photos. The second day was a bit ride down the Saigon river to see a floating temple and visit a reconstruction of a Mekong Delta Village. Both guides took photos of us during the tour and emailed them to us which was a nice touch. Very well organised and highly recommended.
