We did the "Half-day cycling tour to explore the typical values of Hanoi", booked online via their website. The whole experience was excellent. We were picked up and dropped off at our hotel, and were the only ones on the tour. The mountain bikes we had were of excellent quality. Our guide was knowledgeable, considerate and spoke English very well. We loved seeing a different part of Hanoi and hearing about the day-to-day lives of the residents. Highly recommended, would do it again.
