Just want to post the link of photos from my Sapa trip early May 2007. Sapa is a small town in northern Vietnam, ~8hrs train ride from Hanoi. The attraction here is the ethnic minority groups (H'mong, Dzao, Red H'mong, Flower H'mong etc) and the trekkings to the villages.
Photos are here:

Will update this again once I am back from Redang Island trip (11pm tonight!)
