“Keep conversations at a casual volume, refrain from using speakers or playing amplified audio”
The family pool is “heated to a comfortable 95 degrees by the geothermal exchange.” The jetted spa beside it is “above 100.” The 16 geothermal pools range “from 98°F to 112°F.”
“The family pool on the western portion of the Iron Mountain Hot Springs property is the largest of our pools. It is approximately 70′ x 35’”
“All mineral pools are communal, not private.”
“Reservations are not required, but tickets do sell out, especially on weekends, so we recommend booking your soak in advance.”
“Please use the showers to rinse off before soaking.” Waivers “must be completed at check-in and may not be signed ahead of time.”
The family pool is the gentlest place to start. The hotter geothermal pools are next door when your kid is ready, if they're 5 or older.
General Access (All Ages) is $43 to $75 and covers the 16 geothermal hot springs, the family pool, the jetted spa, the cold plunges, a locker, two towels and the Sopris Café. Online tickets are $5 less than walk-in.
Guests under 21 may not enter The Sauna Summit, the WorldSprings pools and area, or the Sandbar Café.
Outside food, drinks and coolers aren't allowed (refillable water bottles are welcome); food is eaten at the café or seated at a chair or table. Guests who are breastfeeding or pumping may bring pumps, breast milk, ice packs, a cooler and related supplies, and private, locked spaces and refrigerated storage for milk are available by request.
A Quick Dip Pass is up to three hours on the property; a Day Pass gives unlimited access all day, with leaving and coming back.
To change a reservation, email your confirmation with the change to info@ironmountainhotsprings.com at least 48 hours before your start time. There's a $5 change fee per ticket, the price may go up, and changes aren't guaranteed. Iron Mountain's pricing rules also say you may cancel or change once for free up to 48 hours before your visit, while changes carry a $5 fee per pass, so ask which applies when you book. Refunds must be requested at least 48 hours ahead; there are no refunds inside 48 hours unless you bought reservation insurance ($10, at the time of purchase), which gives a full refund if you cancel within 48 hours. The $10 itself isn't refunded.
Parking is free. If you park in Lot B, get a ticket from the front gate cashier to open the exit gate.
The property stays open in all weather. If there is nearby lightning, staff make an announcement and guests can move to the Bathhouse or stay in the pools.
A curving ramp with a handrail goes into the family pool, and an aquatic access chair is available.
Minerals in the water may discolor swimsuits; leave jewelry at home or in your locker.
