A few reminders to keep things safe and fun for all:
There is no lifeguard on duty, so kids under 16 need to be accompanied by an adult!
Please no running or diving! 
Keep glass and pets out of the pool area! 
Our pool opens daily at 10:00 AM (Mountain Time) and usually closes around sundown—but don't be surprised- we often keep the pool open later so late comers can enjoy the heated pool in the evening too! 
The pool officially opens Memorial Day Weekend 2026 & closes mid-September 2026. 
We often have pool parties with games and fun you won't want to miss!

Quiet hours are from 10pm to 7am. All children must remain under parental control at all times. Please respect your neighbors and keep your volume down during this time period. Children must be back at your campsite during these hours.

We have an onsite laundry room located in the main building behind the store. We have several washers and dryers and they are open 24/7. Washers cost $2.00 per load. The dryers are 25 cents per 5 or 6 minutes of drying time, depending on if they are the small dryer or the larger commercial dryers. They are coin operated, using quarters. We have a bill changer that dispenses quarters in the laundry room.  Sorry we can't take credit or debit cards for the exchange.  Just cash for cash. We also sell laundry supplies in the store!

Please make sure all visitors check in with the office to obtain a visitors pass.  Only one vehicle with guests per site is permitted.
