★★★★★ 5.0 Erin Hockinson · Sep 2025

Go here! My husband & I were in St. Augustine over Labor Day weekend & I was in desperate need of relaxation after a really stressful trip. Walked into Poseidon Spa (in the historic district) for a pedicure without an appointment & they were able to accommodate within the hour! The spa was so beautiful! Large, antique storefront windows & tall ceilings. I felt right at home from the beginning. Angela gave me one of the best pedicures I’ve ever had. She took the time to remove a pesky/painful ingrown toenail & did a wonderful polish application! She was comforting to talk to (sweet, Southern accent & all), and even fixed my polish after failing the “is it dry yet” test. 😅 I added the hot stones & they were heavenly! Angela even gave me & my husband a complimentary glass of champagne 🥂.

During a recent short vacation to St. Augustine, I had a chance to enjoy a couples massage at Poseidon Spa. Located just outside of the beautiful Casa Monica resort's lobby, I found the Poseidon Spa and its staff wonderful. We enjoyed a 100 minute massage with added hot/cold stone treatment and aroma therapy. Arriving for our appointment, we were shown to a small but adequate changing area that offered a shower, bath products for use, towels, plush robes, and flip-flops (which were a little snug). There's a small waiting area that I found perfectly relaxing with chilled water and tea options. I've seen some people's reviews faulting a lack of snacks, but who goes to a spa and expects to eat before a treatment? That just seems odd, to me. Our massage technicians were professional, went ov

My husband and I celebrated his birthday with 80 minute facials followed with 80 minutes of massages. We were so relaxed and loved all the pampering. The staff were all super friendly and great at their craft. The spa offers a ton of great products and many you can try out in the locker rooms. Great place for a special day or even stopping in for gifts or products. We will be back!
