The Short Answer
A private day trek (terraced fields, Ta Van to Su Pan) typically runs $38-39 solo, roughly doubling per added traveller — though some operators flat-price a trek at $88 regardless of group size. A private motorbike tour (O Quy Ho Pass, Easy Rider-style) runs $103-207 solo. A private Fansipan summit tour with cable car runs $283 flat for 1-2 people. A multi-day private trek with homestay (2-4 days, Mu Cang Chai) runs $259-830 solo, scaling with length and transport (bungalow vs. full car-and-driver).
