World's Coolest Hot Springs
Andy Short/Thermae Bath Spa
Thermae Bath Spa, Bath, England
The Soak: Enjoy a splash of history at Britain’s only natural thermal springs—the water is believed to have fallen as rain 10,000 years ago—which have vanquished stress for everyone from conquering Celts and Romans (their ancient baths are now a museum) to politicians and poets. Although the water surfaces at a red-hot 113°F, the spa’s intimate Cross Bath and rooftop New Royal Bath are a comfy 93°F.
The Scene: Paging Mr. Darcy! One of Britain’s loveliest Georgian cities, Bath is best known for its honey-hued limestone crescents and celebrated resident-author Jane Austen.
When to Go: Year-round.
