A longtime fan of solo retreats, I've traveled much of the world on my own. One of my most life-changing experiences was at the highly regarded Chiva-Som (Hua Hin, Thailand) where I felt anything but alone thanks to a group of likeminded spa-goers I immediately bonded with over dinner at the spa's popular Talker Table. A good friend of mine also had a positive solo experience at Amansala Eco Chic Resort & Spa (Tulum, Mexico), home to the aptly named Bikini Bootcamp. Wanting to engage individual spa-goers, The BodyHoliday (St. Lucia), an all-inclusive health and wellness resort, is introducing a September Solos retreat (starting at $450 per night), which will take place from Sept. 2 to Sept. 30. The month-long fitness-inspired program will include daily spa treatments, group dinners, nightly cocktail hours, weekly sunset cruises, and Champagne concerts in Coubaril Valley. Participants can also take advantage of organized activities, such as a zip-line tour, sports tournaments, group fitness classes, and more.
