Thousand Trails Grandy Creek

SUMMARY PRESENTED BYT-Mobile

Kayaking into the North Cascades and fishing along Grandy Creek give campers concrete reasons to base themselves at Thousand Trails Grandy Creek, a full-hookup campground outside Concrete, Washington, open March 15 through October 31. Sites accommodate RVs up to 90 feet with electric, water, and sewer connections, and the campground also draws tent campers, though at least one reviewer notes the experience works better for those with trailers or cabins given the amenity-forward setup.

The campground runs a mix of Thousand Trails and KOA sites, and reviewers consistently flag cleanliness as a standout feature. Sites are spacious enough that campers generally don't feel crowded, though some note that certain spots sit close together with limited privacy. A security gate and off-road positioning give families room to let kids move around freely. The jumping pillow and creek access are frequently mentioned by families, and organized activities like outdoor movies and ice cream socials appear during summer weekends. ATT cell coverage is reported as solid, and WiFi is available on-site.

"Camp clean and serviceable but boring for geezers," writes Nichol I., which is a useful framing: this campground fits families and RV travelers better than those seeking a remote backcountry feel. The North Cascades Highway runs nearby, opening up day trips east toward the Skagit River corridor. Rasar State Park Campground sits a short distance southwest for campers who want a more natural alternative. Reservations are recommended for summer weekends, when the campground sees its highest activity.

Friendly, quiet, great location

We've now stayed at this campground twice.  It's a bit unique as half the sites are KOA and half are Thousand Trails, but both sections are serene, well maintained, and peaceful.  We use this campground as a jumping off point for kayaking adventures into the North Cascades.

Great for kids

The campsite is great for kids because of the amenities like the pool and other games. Good for people now into glamping. If you're looking for a "nature" experience this isn't it. If you have a trailer or reserve a cabin is great. I wouldn't tent camp here though. Sometimes it's nice to just get away though and still have power and a bed.

Love this place

This is one of the top campgrounds in our rotation. The sites are pretty spacious, lots of stuff for kids to do. This weekend there is a lollipop toss, ice cream social, candy bar bingo, and an outdoor movie. The jumping pillow has been repaired and is (new?) better than ever! Great place to bring the kids. Because it’s off the road and has a security gate, I have no problem letting my kid be a kid. ATT cell service is solid. I was able to use my phone as a hot spot and work a bit, too. BONUS!!

Foothills of the Cascades

Campground provides plenty of sites so you are not on top of each other. Great activities and some of the best scenery to hike, picture taking or just relax. Campground is clean secure for all ages.
