At 3143m Mt. Fansipan is the highest peak in Vietnam and the entire Indochina peninsula. This remote trek provides plenty to see and absorb. As we ascend through the lower reaches of Fansipan, we will pass terraced rice paddies and villages of the H'mong, one of Vietnam's many ethnic minorities

Travellers Advice:

1. be realistic about your fitness level. don't just assume that you are fit because you more or less have the body shape of a fit person. if you don't exercise aerobically regularly (run at least 10km every 2 days), don't even think about the 1 day trip and expect the 2 day to be hard. honestly, we were a bit slowed down because one member of our group was a bit behind in fitness - he did it valiantly, but suffered badly the next day - and he was actually in reasonably good shape.
2. have appropriate shoes. you can buy fake climbing shoes at sapa - probably it is far better to have brought your own from home. good hiking socks are a plus too. probably this means starting to think about Fansipan before you get on the plane to Vietnam.
3. pack light. there's no point in carrying crap you don't need. maybe everybody in your group doesn't need their own camera, for example.
4. dress warmly. i have no idea what the place is like on days when the sun is beating down. i do know that i was very happy for having taken thermal trousers underneath my hiking trousers, a medium weight hat (with anti-rain brim), and a warm top. the trip would have been torture without these items.
