We recently travelled from the North to South Vietnam over 13 days with a private tour guide throughout. We had booked our flights and had some idea of what we wanted to see but contacted Mr LInh Adventures who came up with an itinerary to suit and it was all brilliant. We had a local tour guide at each area we traveled starting with Billy who met us at Hanoi airport and whose knowledge and friendliness was great and a perfect start to our welcome in to Vietnam. We had the highlights of Hanoi in 1 day and then followed on to Lan Ha Bay for an overnight cruise with Calypso then met the following day and drove to Ninh Binh for an overnight stay and then a day in the Tam Coc countryside before boarding an overnight train (met by next guide Hoa, to Phong Nha and spending a day at the national park (zip wire, dark cave, mud bath and paradise cave) over night at the lake house and then a day travelling to Hue via the Vinh Moc tunnel and crossing North to South. Next day greeted by Long and a day around Imperial Citadel, tombs, local market overnight in Hue and then on to Elephant Springs, Golden Bridge in Ba Na Hills and on to Hoi An. Next day met by Miss Phuong with a day round the local Tra Que Village on bikes (stunning local area) and then she accompanied us the next morning to DaNang airport. Met in Ho Chi Minh by Chin who accompanied us around Ho Chi Minh City, the following day to Mekong Delta and last day to Cu Chi Tunnels. The itinerary was action packed each day but with very informative local guides giving you the best out of your limited travel time and lunch was included where they booked you in to the local restaurants that they recommend and had some lovely local specialty foods. Don't feel we would have been able to see anywhere near as much had we tried to arrange things ourselves individually and also had the knowledge that they were their to assist with any problems that may occur. We had a fantastic trip and wouldnt hesitate to use again if and when we return to visit Vietnam as there is still so much to see. Ideally 3 weeks would be good to include Sapa, 2 nights on cruise at Halong Bay, more time in Hoi An for leisure time and beach (such a pretty area).
