At Mansion on Forsyth Park, Poseidon isn't the rageful god of the sea who made Odysseus's life extremely difficult. Instead, it's a spa with the opposite mission: soothing all who visit. Past a reception area with gauzy curtains and sea-blue lighting, relaxation experts perform body, skin, and nail treatments in private rooms.

Of course, many of these treatments have an oceanic theme. The Tranquil Sea Odyssey, for example, cocoons clients in a body wrap while a warm-stone facial massage enriches the skin with phytonutrients. Other services conclude with a cleansing Vichy Shower, and add-ons such as an ocean foot polish or an aqua gel mask elevate treatments to the next level of pampering. The spa even has its own 24-hour cardio fitness facility, as well as steam showers for a post-workout rinse or a pre-workout lesson on how liquids turn to gases.
