Spa Day on Kauai: The Best Resort Spas, Open Now
If you’re not sure what to do on a rainy afternoon, or you just want to make the most of your time while really relaxing, book a spa day. Kauai has some beautiful resort spas, and you don’t have to stay at the resort to book a treatment at most of them. Here are the ones we’ve confirmed are open.

Checked mid-October 2026. Hours and treatment menus change by season. Call ahead, and book couples treatments early.
