It’s strictly 18 and up, so you won’t hear “Marco Polo” echoing across the water. Come here to unplug and feel kind of mystical.
The Inn at Little Washington — Washington, Virginia
Famous for its Michelin-starred dining, but the spa is criminally overlooked. It’s intimate, hushed, and deeply luxurious with every detail curated like a love letter to your nervous system. Book a facial and emerge with the skin of a minor deity. Bonus: you can wrap your day in a robe and sip wine by the fireplace like a fancy adult.
