Hyatt Regency Mission Bay Spa & Marina

The Hyatt Regency Mission Bay Spa & Marina sits inside the Hyatt Regency Mission Bay resort at 1441 Quivira Rd, on the water in San Diego's Mission Bay neighborhood. As a hotel spa, it's built to serve guests staying at the resort rather than operating as a stand-alone day-pass destination open to the general public.

The property falls into the upscale tier, which generally lines up with resort spas of this type — full-service treatment menus, quiet lounge areas, and a setting tied to the hotel's marina and waterfront amenities. Specific treatments, locker-room details, and hours aren't published here, so anyone planning a visit should check directly with the spa or front desk.

Because access is listed as hotel guests only, this isn't a spot to drop into on a whim if you're not booked at the Hyatt Regency Mission Bay. If you are staying there, the spa is part of the resort's broader marina-facing amenities, alongside water activities and the hotel's own dining and event spaces.

For booking, pricing on individual services, and current hours, call (619) 224-1234 or check the hotel's official spa page before you go. Given the limited public detail, it's worth confirming what's included with a treatment, whether any day-pass exceptions exist for non-guests, and what to bring, directly with the spa staff.
