Kona Kai San Diego Resort

Kona Kai Resort sits on 11 acres at the tip of Shelter Island in Point Loma, and its spa, SpaTerre, is the wellness wing of that waterfront property. The spa offers sauna, steam room, and pool access alongside its treatment menu, set within a resort that also includes a marina, private beach, and a fitness center for guests who want to combine a workout with a soak.

Access is tied to a hotel stay rather than sold as a standalone day pass, so this is a spa you visit as part of booking a room at Kona Kai rather than dropping in independently. That makes it a fit for travelers already planning a stay on Shelter Island who want spa treatments, a sauna and steam session, and pool time without leaving the property.

The resort leans into its waterfront setting, with rooms and suites overlooking the marina or bay, and dining that centers on water views. The spa itself is positioned as the place to unwind after time spent on the water, whether that's paddleboarding, boating, or simply exploring the gardens and terraces on site. Given the upscale price tier, expect the spa experience to match the rest of the resort's polish, though specific treatment prices and operating hours aren't published and are worth confirming directly.

For anyone weighing a stay in San Diego with wellness built in, Kona Kai combines the practicalities of a full-service hotel—restaurant, event spaces, water sport rentals—with a spa that covers the core amenities of sauna, steam, and pool. It's a resort-first booking rather than a spa-first one, so plan a room reservation if the spa is the draw.
