Guerlain Spa

Guerlain Spa sits inside The St. Regis Al Mouj Muscat Resort and runs on the Guerlain name, from the treatment menu down to the scent bar and skincare line stocked on site. There are 11 treatment rooms, two of them couple suites, plus wet facilities with steam rooms and saunas split into separate men's and women's lounges.

The treatment list covers 13 options: body scrubs and wraps, facials, eye and lip treatments, scalp and hair treatments, manicures and pedicures, and massages including couples sessions and a track aimed at men. The wellness menu draws on Omani ingredients and traditions rather than a generic international spa script.

Access doesn't require a hotel stay — a day pass is available, and the spa also takes walk-in bookings aren't guaranteed (reservations are the safer route given it's not listed as walk-in friendly). It's not restricted to adults only, so it works for a family trip alongside the resort's kids club and pools, though the spa experience itself is clearly built around couples and solo relaxation. Staff work in English and Arabic.

The spa is open daily from 10:00 to 22:00, and sits within a resort that also has a swim-up bar, adult-only and children's pools, a fitness center, and a rooftop padel court, so a spa visit can easily be paired with a longer day at the property. Price tier lands in the upscale range, consistent with the St. Regis setting and the Guerlain branding.
