A Retreat of Sound, Frequency & Flow with Katrina Baccetti and Sophia Rayne

Join yoga guide Katrina Baccetti and musician Sophia Rayne for a heart-opening Valentine's Day weekend at Harbin Hot Springs. Through movement, breath, sound, and sacred music, we’ll attune our bodies and nervous systems to the frequency of love.

Expect heart-centered vinyasa flows, restorative yoga, crystal-bowl sound journeys, live music under the stars, and quiet moments to simply listen. This retreat weaves silence and sound, movement and stillness—creating space to soften, restore, and remember what resonance feels like.

Katrina Baccetti is a yoga instructor and wellness facilitator known for her heart-centered approach to embodiment and transformation. Her teaching blends traditional alignment, intuitive flow, and meditative presence to support grounding, self-awareness, and inner connection.

Sophia Rayne is a soul/pop artist, intuitive singer-songwriter, and sound healer whose music carries frequencies of awakening, empowerment, and healing. Through crystal bowls, flute, and intuitive vocal channeling, she guides participants into emotional release and remembrance of the heart’s wisdom.

Heart Resonance was born from a shared vision to create an immersive sanctuary for the heart. Through yoga, sound, sacred waters, and the healing power of the elements, participants are invited to harmonize body, mind, and spirit—returning to inner stillness, vitality, and love.

Winter invites stillness, introspection, and rest. Join us for a weekend of yoga, sound, and soaking designed to restore emotional harmony and reconnect you with your natural rhythm.

Tune in. Open up. Feel the frequency of love.

Harbin Hot Springs is located in Lake County, CA and offers spring-fed hot, warm, and cold pools. In the tradition of Japanese onsens, Native American, and European hot springs, the soaking pools and pool areas are clothing-optional. This includes the pools, sauna, and surrounding sundecks.

The clothing-optional Mainside Pool Area now features a total of eight different pools. All these pools are fed by the different-temperature springs on the property. Spring waters are blended, heated, or cooled to produce and maintain the consistent temperatures that guests have come to know and love – ranging from profoundly hot to chillingly cold, and perfectly in-between.

Please be advised that the hot springs & surrounding areas are electronic-free zones. 

Soak in clothing-optional spring-fed pools and sunbathe on the deck overlooking expansive views. Settle in, explore the land, wander the garden, walk the labyrinth or hike the "Spiritual Path". Visit the food court for healthy snacks and delicious meals.

Because electronics are not allowed at the pool area or anywhere clothing is optional, we invite you to embrace your retreat time as a digital detox. You may want to bring a journal, sketchpad, or watercolors. Or visit our beautifully curated bookshop in the Reception Office and pick up something new to read during your visit. You’ll be surprised how quickly you adjust to a signal-free day, and many guests consider this feature to be a Harbin highlight. We hope to make your retreat as comfortable as possible, and we will do our best to make you feel at home.

Remember to stay hydrated throughout the day, especially when soaking.

Warm Pool ♡ As you walk up the road into the pool area, the Warm Pool is directly in front of you: you’ll see the curved stairs leading up to it, and the familiar white railing around it. When people refer to Harbin’s “main pool”, this is likely the one they mean; it’s also where Watsu® was initially developed. The water temperature here is ideal for enjoying long, meditative soaks without getting either too hot or too cold.

Hot Pool ♡ Harbin’s signature pool is its enclosed Hot Pool, under the peaked roof with manzanita-mullioned stained glass. You can enter this structure from the far end of the Warm Pool, or by walking around either side of that pool. The water in our Hot Pool is EXTREMELY HOT – so please enter it with awareness and care. And if you’re not experienced soaking in water this hot, please limit your initial dips to less than a minute.

Cold Plunge ♡ Around the back of the Hot Pool and up a half flight of stairs is Harbin’s Cold Plunge, and the fig-shaded sitting area that is home to our Quan Yin statue. This pool has very cold water, which comes directly from its spring and flows quickly through the pool without any treatment. Many guests enjoy alternating rounds of soaking between this Cold Plunge and our Hot Pool.

Trellis Cold Plunge ♡ The square pool closest to the entrance of the Sauna building is our Trellis Cold Plunge. Thanks to the physics of a pool-to-pool heat exchanger, its water is actually refrigerated – making this pool a truly bracing refresher following a hot plunge or a sweat in the Sauna.

Trellis Hot Plunge ♡ This square pool is located just in front of the Trellis Cold Plunge, and is a perfect mirror of it. Together, these twin Hot and Cold Plunges offer Harbin guests a second option for alternating rounds of hot and cold soaking. The water in this plunge is partially solar heated, and can be VERY HOT.

Heart Pool ♡ Our easily recognized Heart Pool is named for its shape, and located in the trellis area. As in the Warm Pool, the water here approximates body temperature, making it another perfect place to relax for extended periods. Unlike the Warm Pool, quiet talking and socializing are welcome here – as are supervised children from 10am-dusk.

Swimming Pool ♡ Harbin’s big Swimming Pool is the place to swim laps or exercise, lounge about, socialize, and play underwater in the deep end. For safety reasons, though, we do not allow diving into any Harbin pool. The water temperature here varies with the seasons, but is usually on the cooler side, appropriate for active enjoyment; during cold weather, we warm it slightly.

Spa Services Pool ♡ The oval pool under the oval roof was designed and built specifically to give our guests a more-private setting for their professional Watsus® and other aquatic bodywork sessions. Its body-temperature water is the ultimate medium for long, blissful treatments. To book, contact health services at (707) 987-2477 ext. 2000.

Steam Room ♡ Located inside the new Fern building, the brand-new Steam Sauna offers state of the art technology, beautiful, spacious, handcrafted tile bench seating, and ADA space. Please bring a towel to sit on.

Dry Sauna ♡ Our dry Sauna is more than twice as large as the one it replaced. It’s a beautiful cedar Sauna with ample seating and custom woodworking – including window, lighting, and railing details crafted from Harbin trees. Please bring a towel to sit on.

Sundeck ♡ Clothing-optional sunbathing is a favorite Harbin activity. Our sundeck (accessible by elevator from the ADA parking below) gets beautiful sunlight from early morning through midafternoon.

Fern Dressing Room ♡ Construction is complete on the new Fern building, bringing more poolside showers, four restrooms, lockers, and hair dryers to the Mainside Pool Area.
