We did two days of tours with Billy Private Tours. We were picked up from the airport in Da Nang and that’s when our tour started. We spent the first day in Hoi An exploring the Old Town. The next day we started early heading to Monkey Mountain, Marble Moutain, Hai Van Pass and finishing at Ba Na Hills. It was a big day but it was worth it especially due to the reduced tourist numbers making Ba Na Hills very quiet which made it much more enjoyable. Thuy was a fantastic guide and we’d recommend Billy Private Tours to anyone wanting a private tour.
