About Colonial Creek South Campground

Colonial Creek South Campground in North Cascades National Park is a remote, yet bustling campground nestled in old growth forest. Located on the south side of State Route 20 near mile marker 130, there are 94 campsites that are surrounded by forest and located on Diablo Lake.


Visitors can access several trails from within the facility, such as Thunder Knob Trail and Thunder Creek Trail. Colonial Creek South Campground is also close to several trails along State Route 20. Visitors can also go boating, fishing, and swimming (although the water is a chilly 43 degrees) on Diablo Lake. Bears do inhabit the area, so care should be taken when hiking, picnicking, or camping.


The campground is located on the southern side of State Route 20, with some campsites along the lakefront of Diablo Lake. The entire facility offers drinking water, flush toilets, garbage removal and some paved parking spaces, but most sites have uneven gravel parking. Each campsite offers a picnic table and campfire ring.

This Lake!

Diablo lake is one of the most stunning sites my eyes have feasted on! We love this campsite. We’ve done first come first serve here, but I think that there are reservable sites too. The hiking, the swimming, the drive in! This place is truly magnificent and magical.


We were surprisingly pleased with this campground. Our site was was a tent site only. The sites are spread out and do offer a little privacy. The sites have a picnic table, fire pit and a bear box. The restrooms a bit dated and you could defiantly tell they need to be updated. Diablo lake is beautiful and plenty of hiking trails to keep you busy. We will be back.

Absolutely amazing

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.

Good location

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.

Favorite campground in the area

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!

camp at diablo lake

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.

Relaxed and Refreshing

Colonial Creek is right on Diablo Lake. My boyfriend and I were at a spot with the water just in the other side of the trees and it was phenomenal. We had a deer walk through the campsite the next morning, but other than that our spot felt secluded and was one of my favorite campsites I have had.

Beautiful lake and a network of amazing trails

Colonial Creek is situated in the heart of the North Cascades. It has easy boat access to Ross Lake and trails along Thunder Creek. Has clean restrooms and spacious campsites. Sites are first come, first served. Sites are wooded and bugs were minimal.

Quiet, peaceful with raw beauty along all the trails and lake.

It is a very clean peaceful campground, many trails to explore and view the mountains and glaciers that are just stunning. Many old growth trees that dwarf you in this majestic place.

Jumping off point for great trails

Not super quiet but not crazy busy. Close to water and great hikes!
