This is small campground associated with a motel that opened before the season had started for us. The owner went out of his way to provide water for us as it was too early to turn the water on for each individual site due to freeze up potential. It was a beautiful level site. Luxuriant grassy setting.
Campground is operated by City of Cambridge. It is well maintained with clean washrooms and showers. No reservations. First come, first served. "Honor Box" to deposit the $15 per night. 3 night maximum. Local residents can only stay by special permit. Very wide sites with mature cedar hedges between. 7 sites with 15 amp power and 7 with 30 amp. 3 sites with water. City bus stop 8 minute walk away. We stayed 3 nights and were all by ourselves. Open to public dump station and water supply.
This is no longer a KOA, but called Serpent River Campground. Site was great, easy pull-through. The only concerns I had was that the dump station is on a mound and my front wheels on the motorhome were on the down slant by the time the dump valve was aligned with the sewage hole. I didn't get a complete dump. Very friendly staff.
