One of the standout features here is the family-friendly atmosphere. The campground boasts a swimming pool and splash pad, perfect for cooling off during the warmer months. There's also a playground, though it could use a bit of TLC, and plenty of activities to keep the kids entertained, like bike rentals and putt-putt golf.

For those who like to stay connected, the campground offers WiFi and good cell coverage. Pets are welcome too, so feel free to bring your furry friends along. Just remember, while fires are allowed, you'll need to bring your own firewood as it's not available on-site.

Great campground

Loved our we can there. The site was a little bit muddy but no big deal. We were right by the restrooms which were nice they have a nice dump station and lots for the kids to do. The playground could definitely use some up keep there was a lot of rust and sharp metal pieces. The camp store definitely needs updating they hardly had anything in there. All in all we were totally go back is really relaxing and beautiful

Off Season and No Water

We love camping in the off season but with that comes closures. Some sections of the campgrounds might not be open, no camp hosts and limited bathrooms and showers houses. This is to be expected, but when I called the morning of our trip to make sure potable water was available and I was told yes it was only to drive 2 hours and realized they were wrong. No water πŸ™. This would not have been a peas we have dry camped before but all the bathrooms were closed as well.

After called the park ranger he did let us get some water at the maintenance building so we were at least able to finish the weekend. Lesson learned always pull with at least some water.

Now back to the campground itself was nice and clean. Site are a little close together. The biggest down side is you are there to enjoy the lake but the lake had algae warnings everywhere not to go near the water.

They do have a dog park, pool and splash pad when in season and a marina. Also they have WiFi and good cell coverage.

2nd time with new camper

This was our second time here but with our new camper. Great location of pull through sites for families with kids because of proximity to playground. This will be a regular spot for us in the coming years.

Nice quiet campground

The pull through area is very cramped; more like a parking lot; the campground is quiet; family friendly; no golf carts all over;

Great campground near home with decent amenities

The camping spot was great. It was very close to the pool and playground. The sites were pull through which was nice for have young kids. Could sit at our spot and watch our kids at the playground. This particular week there were tons of kids and our kids had a great time. This site is only a 15 min drive but it feels like its further away. While we get used to being campers having close spots helps us learn.

Family Friendly

Great sites, awesome new pool.

Huge sites!

My husband and I drove 8 hours to visit family and decided to camp here instead of staying in a hotel. It was great! The showers were always clean, the site is huge compared to what we normally stay in. It was pretty cheap per night. Our site was nicely shaded.

There must have been a nest of some type of bug in our site because I was bit dozens of times but bug spray pretty much fixed that.

Beautiful views

friendly staff, very clean restrooms, playground, could not swim in the water due to contamination which they have spent millions to repair and is slowly on the up and up, not too far from town, surrounded by many park accesses to Grand lake for fishing, boating or just hanging by the water. The lake is so big, it was like being on the ocean!
