Campground Reviews

Jun 25, 2025
We had a good stay. We needed to bridge our National Park reservations for a weekend. The stay at Grandy Creek KOA enabled us to get caught up on laundry, charge all our devices and fill our water. We enjoyed the campground atmosphere (not a parking lot) with the tall trees. The staff was helpful and polite. The laundry room was clean. Unfortunately half of the showers were not open.

Lovely spot in the Cascades. Beautiful tree stand and the kids had plenty to do. We used the laundry area and found it to be one of the best we've seen and used. Quiet too.

Noisy neighbors at night. Noone was taking care of that. The heated pool was a good ad for a cloudy day for my kids. Table at our spot could be a little bigger but ok

Our two children and their spouses along with 5 grandchildren joined us for our stay. The grandchildren were entertained by the many activities and played in the open field near the camp site allowing the parents to watch their kids and enjoy their stay. The weather was predicted to be very wet, fortunately the rain came in the night making the days enjoyable for all. A good experience for all.

It was just a short stay for us. The Entrance staff was extremely nice and helpful, the grounds were lovely, and the RV/trailer spaces were quite large, and well-spaced. There is a pretty creek neighboring the park, and they have a cleared space with a picnic table to enjoy the creekside. Nice amenities including a pool and hot tub, both clean and well-maintained. Nice activities for kids!

We stayed in one of the yurts for 2 nights. Our window screen was tied so tightly that I had to have maintenance come and adjust it after the first night of it being open. They responded quickly and were able to fix it. The bathroom house was large but half of the showers were out of order; the ones that were usable were either missing shower curtains or had large clumps of hair/debris.

Amazing facility and amenities! Absolutely the nicest and cleanest KOA we’ve stayed at! Shout out to Bryan for being so helpful and awesome and ensuring that our stay was perfect.

We enjoyed the property overall. The cabin we stayed in was clean and very nice. It worked well for our family of 4 with 2 kids ages 5 and 7. The only complaint is that the pool and pillow have late opening times, and both mornings I had to go track down staff to open the jumping pillow because they "lost track of time." It was supposed to open at 10 but it did not open on time both mornings.

Kids love the jumping pillow and I love the quiet retreat areas like the bench swing and the mini golf and trail.

We had a great time, we rented one of the luxury cabins, it was so cute and perfect. Our kids had so much fun riding their bikes around the property, and playing in the little creek. We will definitely be back!

Spots are narrow and very close together. Staff was great. Very expensive for what you get. And now bringing in full timers is only going to make it worse.

Very nice KOA! Check in, the store, amenities, and layout are great. Site was nice and level, spacious, and with nice large trees. Restroom was good and clean. Shower stalls are cramped.

I recently drove to Alaska and was looking for a KOA close to the Canadian border. What a pleasant surprise to find Concrete/Grandy Creek. It seems a little out of way for crossing the border into Canada but I found it convenient to the border crossing in Sumas. The staff is amazing and the property is in a quiet setting and offers a lot of amenities. I stayed there again in my way home.

All staff friendly. Love the decorations and activities planned for the holiday. Delicious breakfast.

Friendly staff, clean campground, decent sized campsites. One of the group tent sites nearby played loud music all night right up to the 11pm quiet hours each night, but overall another enjoyable stay at the Concrete/Grandy Creek KOA

Not happy with the WiFi service. Paid for a week, took 2 days and several service calls to activate then it didn’t work well at all.

everything look super good and clean. Staff was very good. bathroom were very nice and clean and well stocked. Looking forward tp my stay in june.

Good campground. Clean, however quiet time should be 10 pm not 11 pm and kids should be better supervised. Very nosy.

I would have rated it higher if we didn't wait at the gate for 1 hour. Rules can be broken this time of year. There isn't many campers and are spot was ready next to are friends. So I believe telling us to wait was unbelievable. Didn't even make common sense.

Campsites were well maintained. Park staff was helpful too.

The staff gives you a warm welcome at the gate and continues to offer help during our stay. Visiting the store was I highlight for the kids and adults to get a treat and souvenirs of our stay. Eric is absolutely fantastic! He is engaging with all who enter the store young or old. Thank you all for another great weekend

Other than the rain (obviously not anyone's fault) it was fun like usual! My kids were sad about not being able to do the hay ride but with so much rain it would've been a mess.

We had an amazing weekend at the campground. It poured rain the entire time, but the staff and the other guests were so friendly and no one seemed to mind the weather. That’s how much fun the campground is.

Not a very pleasant stay, especially being handicap staff continually telling me I can't park here or there after 2 days and having to park a distance from my campsite. I wanted to ask for a full refund for the unfortunate situation I was put! Thank goodness it was only 2 day's. I've stayed at the winthrop koa and never have had an issue. Thank you.

Spacious RV camp sites and friendly staff!

Our goal was to surprise a friend and the front gate attendant was amazing in helping us do just that. She was also very happy at her job which is always a nice treat!

We stayed here four nights in a 40 foot fifth wheel in site number 97. The site was wonderful! We were level and at the end of a row with private space in three sides. We have never stayed in quieter campground. Sleep was wonderful. Laundry room worked well but could have used a cleaning. Bath and showers were clean. The only gripe we had is that the camp store wasn't open until Thursday we are told so we had to go out of the park to get ice.

We only stayed for the night but Terry, one of the staff, was so kind to let us borrow his personal30Amp adapater because we didnt have one. Thanks Terry! Nice and quiet, we will be sure to come again for a longer stay with the kids.
