4/5
Nice facilities and clean sites. Our spot had a great view of the water, though the laundry machines could use an upgrade.

Nice relaxing vacation spot
Loved the location. Spent a lot of time by the water. The sites are simple but kept clean. Will likely come back next year.

Okay stay but sites are tight
Nice views, but the RV sites are very close together. We barely had room for our slides and the picnic table was awkward.

Beautiful location and friendly staff
The park is well-maintained and the staff is so helpful. We had an issue with our electric hookup and someone came over immediately.
