indoor pool and hot tub



Happy fall everyone - the summer season is winding down, and we are looking towards our fall schedule at the pool . it is unfortunate that we have been unable to provide you folks with our indoor pool facility this summer…..

Our re-opening plan is as follows, and is subject to change based on future changes in State Regulations and how the plan is working. State rules only provide for "Lap" swimming at this time.

*We are going to open Tuesday, October 13.

*Hours will be Monday through Friday, 9:00 to 5:00 to start.

*At this time, we are going to offer the pool for exercise and therapy use only - NO recreational swimming such as open family swim or birthday parties.

*Swim sessions will be in 45 minute blocks,, with 15 minutes between each block for cleaning. times are on a first come, first served basis.

*Appointments must be made prior, no drop ins please.

*Pool will be limited to 6 people at one time. There will be assigned areas in the pool - two deeper water, one mid- pool, two in the shallow end and a lane open for lap swimming.

*We ask that you arrive in your suit and have limited use of the restroom and shower facilities. Exit will be out the side door.

*When you make the appointment, you will be asked Covid questions, and again when you arrive. PLEASE do not come if you are sick or have been around any one who is or has been.

*Masks are required when entering the building , but removed once in the pool room. Masks are not to be worn during swimming for safety.

*Those folks with punch cards that were current in March, will be extended the length of time we were closed. If your card was expired in early March or previously, it will not be extended.

*Please be on time for your appointment - if you find you cannot make that time, let us know asap so we may offer that space to another swimmer. (As we are limited to 6 at a time)

We appreciate in advance your patience and understanding as we attempt to work through this - We are bound by State Regulations and we are trying to figure out the best way to follow them, provide you service and keep everyone safe. Indoor pools have different rules than outdoor pools….

The campground office is open 9:00 to 7:00 for appointments - we will do our best to accommodate everyones wishes. Please call the office - email and messenger will not be answered as quickly.

Again,, thanks in advance for your patience. Please understand that the closure since March and new (temporary!) procedures are not our choice :(
