The largest city in Thailand is more accessible—and far more calm—by the river, exemplified by the lush boutique hotel The Siam and its one-of-a-kind approach to culture, wellness and design. Weave through a quiet-for-Bangkok neighborhood’s palaces and tall walls, and you’ll reach the tranquil entry. Noted as one of the Thai Princess' favorite spots, the blood pressure-dropping palette of all white, black and electric green creates an unmatched sense of arrival. Walking inside feels akin to a fantasy. Ferns drip overhead, glowing with sunlight from a glass pyramid above, while a hall of towering banana leaves arcs over the world’s most elegant reflection pool.
