Equinox is more than a spa, it a high end, full service gym. Bostonians in the know join Equinox for top notch fitness, but take advantage of the on-site spa after workouts. Although it is not easy for non-members to enjoy the gym (having to shell out $50 for a day pass) a service at the spa at Equinox allows you instant access. Book a massage, facial, wax, body treatment tan or healing session and enjoy the gym and its amenities for the day. If you have children with you, take advantage of the on site daycare while you get in a good workout and enjoy your spa service. Then get glamorous in their state of the art locker room stocked with Kheils products before heading back out onto the bustling Boston streets.
