Away from the South Beach fray on Belle Isle, The Standard Spa is part of Miami’s most storied hotel, which features cute bungalows set in lush tropical gardens (with fire pits and hanging chairs) and an outdoor restaurant on a deck over the water. The entire third floor is devoted to the spa, which includes hydrotherapy treatments, a capacious circular marble hammam and yoga classes, but it’s best known for the detoxifying mud baths that you can take al fresco. §
