Like Ha Long Bay, Hoi An is a UNESCO World Heritage site and a popular tourist destination in Vietnam. The historical district is recognized as the best example of a historic SE Asian trading port from the 15th to 19th centuries, according to Wikipedia. But to the non-Googling eye, the area is an incredibly quaint, well decorated old town with clear Japanese, Chinese, and French influences. Presumably, because they all traded there.
Ha Long Bay is a UNESCO World Heritage Site and was our second destination in Vietnam. The bay is full of thousands of picturesque tiny limestone islands that abruptly pop out of the ocean. The area is strange and otherworldly. So much so that local legend says a dragon spit jade bullets into the ocean, which sprouted these islands in front of enemy ships. Seems logical enough, right?
