Harbin Hot Springs near Middletown is a paid, membership-based retreat, not an informal creek swim. The manager describes hot, warm and cold pools, plus a large pool for lap swimming. Pool areas are clothing-optional. Decide whether the retreat atmosphere and rules suit your group before booking.
As checked October 8, 2026, adult six-hour passes cost $45 Monday-Thursday or $55 Friday-Sunday. Membership is additional, with a $15 one-month trial, $35 annual membership or $300 lifetime option. Children have their own pass rates. Book ahead, bring physical photo ID and review the final total, deposit and cancellation terms. Everyone arriving in the same vehicle must buy the same pass length.
The first Tuesday of each month is normally pool maintenance day. The warm pool, cold plunge and hot plunge are unavailable while being serviced and refilled, while the manager lists other pools as available. Construction can also bring noise. Check current notices instead of assuming every pool is open because the retreat operates year-round.
Children may use only the heart-shaped and large swimming pools, with an accompanying adult, during the published child-access hours: 10am-8pm in summer or 10am-sundown in winter. Expect an uphill walk from normal parking; ask about the specific ADA facilities if needed. Bring your own pool towel and a locker padlock. Visitor photography is prohibited anywhere on the property, and electronics are not allowed in the pools or clothing-optional areas.
Paid 24-hour passes include camping. RV and ADA tenting arrangements require a call, and vehicle restrictions apply. Indoor lodging has weekend and holiday minimum stays. Use the current rates and accommodation details to choose your stay rather than treating a day pass as overnight permission.
Use 18424 Harbin Springs Road, Middletown, California 95461 and the manager's current arrival instructions. Follow signs to reception for check-in; when reception is closed, report to the front kiosk. The retained historical map point is not a verified entrance or pool-access pin.
Bring physical photo ID for guests age 18 and older. All occupants arriving in one vehicle must choose the same pass length. Six-hour passes run from arrival or until midnight, whichever comes first. Check current construction notices and the first-Tuesday monthly maintenance schedule before choosing your date.
Confirm the entrance, parking arrangements, and legal access with the land manager. A map pin does not establish a public right of access. Follow posted routes and never block gates or driveways.
Current swimming permission has not been independently confirmed for this listing. Check official rules, fees, hours, and closures before visiting. Public park access does not necessarily include permission to swim. Respect private property and posted restrictions.
Water conditions can change quickly. This listing does not provide a current safety or water-quality assessment. Check official alerts and avoid entering water when conditions or permission are uncertain.
Bring sturdy water shoes to protect your feet on rocks and slippery surfaces. A waterproof dry bag keeps your phone, keys, and valuables safe. Pack a quick-dry towel, sun protection, and drinking water - never drink from the natural water source.
