This gorgeous retreat is nestled within a tropical rainforest on the northwest tip of the island Langkawi off the coast of Malaysia. While the setting alone is enough to make you feel instantly relaxed, the retreat also boasts an expansive spa set among the mangroves next to a small winding stream. Treatments incorporate healing plants found in the rainforest and philosophies of the Malay culture known as Ramuan. There’s also a collection of manicures and pedicures available from leading podiatrist Bastian Gonzalez paired with relaxing massages to boost circulation. The sprawling 37,500-sq-ft Datai Estate Villa boasts two connecting pools and comes with a 24-hour in-villa butler to take care of your every need.
