This RV park is very well maintained with an attentive and friendly staff. We stayed in site 70 with beautiful lake views and high enough off the water there were no mosquitoes. While there is access to the lake, there is a sudden and deep drop off a few yards from the shore so swimming is not allowed. A short drive away is Ike Kinswa Park which has family friendly swimming areas. Harmony has plans to expand and add a swimming pool in the future. We would definitely visit again, especially in the lakeside spots (67-72 were our favorites).
The location is fantastic - we were backed up to the Nehalem Bay. We rented crabbing equipment onsite and crabbed from the docks. They cooked the crabs for us then we made a fantastic dinner overlooking the water. The challenge with this campground is that it's essentially a parking lot with RVs parked close to each other. The weekend we visited was not too busy so we were able to enjoy some space and the view. Be sure to ask if they are having any events (such as a their monthly karaoke contest) before you go. We were there on karaoke night and the music was so loud we couldn't escape it. It started around 6pm and went to 11pm. Thankfully our 5 year old was able to fall asleep, and by 11pm there was solitude again.
The concept of the campground is great. Everyone we met was friendly and their vehicles/equipment were nice. We enjoyed the swimming pool and being able to access the Salmon River. The campground has beautiful trees, clean bathrooms and plenty of room between sites. The sites themselves have not been maintained. They are gravel, most overrun by weeds and in our space, the fire pit and table had been moved and were not back in their intended space. We had to move it ourselves. It doesn't appear there is regular maintenance of the sites which is too bad because again, the concept is great. We will watch to see if they make updates, if not we will likely find other options in Mt Hood National Forest.
