Summer is dwindling away faster than you can say “back-to-school sale.” At this point, though, it’s probably too late to organize a vacation, and spending your weekends at the pool is starting to get old. So how do you enjoy the remainder of the sunniest season.

We believe there’s summertime fun in store for you yet. The key is to organize some time for yourself with a weekend full of pampering—though a day or even a couple of hours will do the trick, too. Whether you choose to indulge in massages and facials or guided meditation and sauna sessions, a summer spa retreat will leave you feeling relaxed and restored. That is, as long as you’re prepared for your spa visit beforehand.

But Groupon not only has you covered in terms of beguiling spa offers, but our Beauty Editors have also assembled a directory of the information you need to make your spa retreat as effortless as possible.
