The northwest market town of Sapa is colorful and charming, providing the perfect oasis in the midst of a strenuous mountain trek or rice-paddy tour. The Gothic stone church at the center of town is a bull’s-eye in the center of shops and stalls, serving as a reminder of the town’s French missionary influence. Dine on Vietnamese or European-inspired cuisine downtown, and don’t miss the Saturday night “love market,” one of the most potent—and strictest-single’s nights imaginable.
