Dear Theona campers,

When we bought this business 35 years ago, we didn’t know how long we would own it. Kathy and Walter were young, and Bill and I were just kids. We all worked hard to provide you and your families with an enjoyable camping experience every summer. We saw many families come and go, and many families who wanted nothing more than to come back to our Park every year. It was particularly enjoyable and appreciated to see several generations of the same families enjoying our Park.

Now, as Kathy and Walter are seniors and Bill and I are getting older, we have decided to close this chapter of our lives. Our families need us now more than ever.

We had not planned on selling the Park this year, but an unexpected opportunity arose, and we decided that the timing was right for our family.

We would like to thank all of our customers, past and present, for your patronage. We appreciate all of the friends we have made over the last 35 years. We take with us so many fond memories which will never be forgotten.

We have sold the Park to Summerhill Resorts Ltd. who have experience in running recreational parks. Bill and I will be assisting Summerhill Resorts Ltd. in the transition period.

We hope you enjoy many more years to come at Theona Park.

Please note that the e-mail address for Theona Park will change to Please direct any inquiries to this address.

Beachside Relaxing

We’re located on beautiful Buckhorn Lake. There’s really nothing better than casting a line in the water on a hot sunny day or going for a picture perfect boat ride.
