Navigate the famous Tham Ma Pass, known for its series of tight, winding hairpin bends snaking up the mountainside. This iconic stretch of road on the way to Dong Van is a favourite spot for photographers capturing the dramatic curves of the pass against the mountain backdrop.

Legend says the pass was historically used to test the strength of horses carrying goods uphill. Successfully driving or riding up Tham Ma Pass is a rewarding part of the Ha Giang Loop adventure.
