Great off season campground

Our camp spots were close to the lake. The cedar trees gave great cover from the rain. The trails around camp were well maintained.

Convenient spot

Lovely but busy spot in North Cascades NP. We were fortunate with really good weather. You can swim in the lake, there is a boat launch and there is a hiking trail across the street. Super convenient. Thunder knob trail.

Bathrooms were clean. Sites a little close. Lots of people come into the park on the weekends from Seattle though it is the least visited of the three Washington Parks. Lovely scenery, turquoise lake.

You need to be prepared when you arrive. Closest camp store is about 25 minutes with limited supplies, but can get you by.. there are restaurants and gas stations in Marblemount, but that is all from what we could tell.

Beautiful Location

I generally enjoyed this location in North Cascades National Park. It is a beautiful area with hikes nearby and chilly swimming. Mosquitos weren’t bad which was a relief. However, sites at this campground are close together and not very private. It feels a bit like a carnival at times instead of camping in the woods.

We found ourselves in the middle of the Pace family reunion while visiting. Apparently all the adults coordinated and rented sites by each other for this event instead of renting a group site. The adults yelled across our site to each other, their children ran through our site to adjacent ones, and they were up and noisy by 6 AM. We also were treated to dirty looks, I’m guessing because it was their “usual spot”? They said they camped there for over 30 years so they clearly feel like it’s their private park at this point. This certainly impacted our enjoyment, and ability to relax.

In the future, we will consider a site away from the water for more privacy.

Despite the presence of bears, there was also a pretty cavalier attitude to bear safety and adherence to those rules. There were a lot of kids and adults day drinking so they just weren’t as alert as they should be. This can put those around them at greater risk for a bear encounter. A fed bear is a dead bear, so this was frustrating to witness.

Stunningly Busy

We were super excited to camp at Colonial Creek. I've read so many reviews saying this is the best place to camp in the N Cascades. I imagine your experience will be different on any given night based on the community camping at the time. But, boy would I ever think twice about camping here on a summer weekend again. It seemed like every site was over capacity with many cars and tents and huge groups of people jammed in everywhere. The result is complete chaos of barking dogs and screaming children and parties going late into the night. On the weekend we were here it seemed like a group of 50 or so folks had rented several sites and would gather to sing & talk lake into the night each night. Because there were SO many people at each site there were often lines at the bathrooms. That said, bathrooms were clean.

We were in site 163 which is huge with a huge tent pad. That said, it is almost a twin site with 162 and tons of traffic. Like, you could almost stand between cars parked in both driveways and touch them.  The sites on the lake side of the inner loop (like 157, 159, etc) seemed more private and away from the ruckus. 

If you are a rooftop tenter it's probably worth noting that the parking spots for even the drive-up lake-side camp spots are basically in a parking lot/on the road and most of the campsite itself is a bit of a walk to the lake.

Pretty but noisy

Colonial creek south #80 is our favorite site. It's a double site so there's room for a couple of tents, close to water and toilets. The sites close to the water are packed tight, often one on top of another. No privacy. We had screaming kids at all sites around us, so it was hard to relax. Still a great campground. We saw bald eagles, hawks and deer. There were bears sited within the campground, so the rangers were being very vigilant.

Awesome car camping spot with waterfront camping

What can I say that others haven't!? Some of the best car camping in the Cascades. The lake is shockingly blue and COLD, but after a sweaty day of hiking is the ultimate in refreshment! Camp sites are close but feel secluded enough. If you walk into the tent sites on the north side of the campground you have some better options if you want to lug all of your gear with you.

North Cascades National Park camping at its finest!

This is by far the nicest campground in North Cascades National Park that one can drive to.  If you are lucky to be able to reserve beach side spots on Diablo Lake you will also have lots of privacy and incredible views of this amazing turquoise blue lake and maybe even your own water access/beach.  If not, the dock and beach are only a few steps away. Bathrooms are pretty basic, no showers. Cell reception is non-existent.  Amazing access to the lake and incredible hikes from your campsite!

So Awesome

Colonial Creek South was SO busy when we visited but still so awesome!!

Finding parking can be the first challenge. Due to the boat ramp and hiking trailheads there are A LOT of people/ vehicles. Getting a reservation can be a challenge, good luck. There are walk up sites also, however the system they use can be a little frustrating. Time of year and day of the week I’m sure factors in.

Once you are in though it is deep cedar/pine forest camping. Several walk in sites are right by Diablo Lake which is beautiful. There’s bear boxes at each site , picnic tables and areas to set up. Water activities galore and hiking trailheads in the area. So much to do. I want to go back!

Great Lake Access

I’m not by any means a pro fisherman but this camp gives great access to any fish that stray away from the lake in to the inlet. The sites are pretty spread out compared to other camp sites in western Washington for sure. Everything is pretty open and there is a nice trail at the end you could take to go backpacking or just a day hike

Social Distancing - Great Place

Campgrounds are full. Camping is one of the safest ways to get out and about yet still practice social distancing. Luckily we planned our trip before COVID-19 appeared and we were able to go on our trip in spite of COVID. And luckily we had reservations. Colonial Creek South Campground on Diablo Lake was a wonderful place to camp. Our site was big enough for our A Frame Pop Up camper and it had a nice private picnic table and tent area we could have used if we’d had extra people camping with us. We were right across from the camp sites that backed up to Diablo Lake and have already scoped a camp site on that side we’d love to check out next summer. There’s lots of lovely hikes in the area. The campground was kept very clean. Kayaking, boating, swimming (although the water is cold) - the lake is a beautiful turquoise jewel in the heart of the North Cascades. We can’t wait to go back.

So many people have dusted off their camping gear or bought new gear and are out and about. Colonial Creek North Campground, which is not reservable, was full mid week. Usually we’ve been able to get non-reserved camp sites mid week easily. So just a word to the wise if you are going camping, arrive early or get reservations where possible.

I wasn’t really sure what to expect from this campground. The maps made it look tight and the park didn’t make much sense to me but I was in for the biggest surprise of our trip. This campground is astounding. The spacing was great especially for a national park campground, the walk ins weren’t to far away but not to close either, the bathrooms were placed appropriately and the attractions are right at your site. There had to have been a dozen old growth giant trees in our site and the views to really help you relax. The bathrooms didn’t have a shower and you could tell the plumbing was old but it didn’t matter. The sites all have a normal fire ring and table. Our site was for tents only and it is recommended to check each site before you book a reservation. Reservations are a must here as well.

Our family really liked the camp ground itself. The only complaint really is other campers. Our "neighbor" obviously wasn't in the know about campground etiquette. Spot lights on until 11 PM and were very loud. But the campground was in a beautiful area close to the beautiful Diablo lake view point. The lake was right at the campground and it was just amazing.

We loved this campground! In the off-season only a few walk-in sites are available for free. The main restrooms and water are locked up, only a vault toilet is available at this time. Site #64 is the best site, much farther away from the nearest campsite and larger. This campground was very quite during the weekends but got busy on the weekends. Next to a few popular overnight hikes, right on the lake, boat dock access. Beautiful spot!

This was our first stop of a 7 day road trip! We arrived in the dark and only stayed for the night. Surprisingly there were plenty of open spots! Our site was small, equipped with a bear locker, fire ring and picnic table. The camp ground had flush toilets, the bathrooms were very clean. They also had a garbage and recycling service, and even potable water available. We explored the camp ground during the day. This camp is right at Diablo lake! There were even camp sites right on the water! Fully accessible fishing pier and boat launch. Kayaking was rough as the winds were strong while we were here. Hiking and more available to those that stay. Fishers had a place to clean their catch! We paid 16 dollars for 1 night. Typically camp at dispersed sites but I would certainly stay here again.
