I stayed there for a couple of weekdays in mid-July, and was had the place largely to myself except for a fairly substantial porcupine that wandered through one morning.  The spots are well-spaced but most of them are pretty shallow, and not suitable for larger rigs or trailers.  I did see one large class C using the group camping area, which is basically a large parking lot with an outhouse and trash bin.  But, because many of the spots aren't great they look like they're not getting a lot of use (overgrown).  Still, the good spots are great and the campground is as tidy and well-kept as we've come to expect from BLM Alaska campgrounds.  Easy creek access!

BLM has the most well-maintained campgrounds in Alaska, and Marion Creek is among the tidiest.  It's very clean and quiet, with reasonable privacy between spots and well-placed pit toilets and bear-proof trash cans.  The surrounding mountains are quite beautiful, and Marion Creek itself is lovely and looks very fishy (although I did not fish while there).  I stayed two nights, and would happily stay there again while traveling the Dalton.

Although the state currently lists the campground as open, visiting there in mid-June I found that it looked essentially abandoned.  There was no fee collection, the toilets were locked, and the fire ring in the site I chose apparently had no fires since last year, as it was covered in dried leaves.  Other sites were similar.  Nobody else camped there the night I stayed.  Overall it was a slightly creepy experience.

That said, it's a lovely location with heavy foliage providing substantial privacy between sites, and several sites are adjacent to the creek (which was running a bit high and fast for decent fishing the night I was there).  The sites were large, with picnic tables and fire rings at each one.  The mosquito situation was about normal for that part of Alaska (bring bug dope).  Water is available, but boil before using.

Not sure what the heck is going on with its status but I would guess it's pretty nice when it's being maintained.  That said, I'm not sure I'll be back - it's about 40 miles from the Eagle Trail SRS, which is really nice.

This is a fairly standard state-run campground on the upper Chatanika River. It's somewhat popular with Fairbanks locals but because of its proximity to town is not a place you're likely to stay if you're heading up the Steese.

The camping spots are small and there's relatively little privacy, and the facilities are, in general, not as well-maintained and clean as we've gotten used to with BLM campgrounds in Alaska. Several camping spots are right on the river. Fishing on the Chatanika is inconsistent but can be very good at mid-summer. If you continue west of the campground there is primitive camping on gravel bars on the river, but you'll probably want 4WD to get there. Also, note that there can be very good berry picking on hillsides near the campground in August and early September.

The BLM has some of the nicest campgrounds in Alaska, and this one is no exception. There are 12 sites with plenty of space between, although they're small for large RVs and trailers (it was perfect for my teardrop trailer). The sites are not directly on the Chatanika River, but you can hear the river running in the background and there is a trail that runs along the riverbank between the campground and the day use area. There are a few walk-in tent sites between the main campground and the river, as well.

Like other BLM facilities it's cleaned and well-maintained, and there are signs up showing local wildlife. Each camping spot has a fire pit and picnic table, and there is a pump to get untreated water near campsite 7. Because it's only about an hour from Fairbanks it doesn't get much traffic from people passing through, although it can get busy during hunting season.

This is a small, quiet campground just off the Alaska Highway between Tok and the border, sitting on the edge of a lake in the Tetlin National Wildlife Refuge. Most of the campsites are directly on the lake, but the ones away from the lake are large and relatively isolated, giving you the feeling of camping alone. It's also worth noting that mosquitoes can be fierce in this part of Alaska and it's less bad away from the water, although it's such a lovely lake that you might prefer to tolerate them in exchange for the view.

There's a small boat launch, a viewing platform, and a nature walk on an elevated boardwalk (which also makes it ADA accessible). The waterfowl viewing is excellent. I've stayed a number of times, spring through fall, and it's always a treat.

This campground isn't directly on the West Fork of the Dennison, but it's an easy 1/4 mile walk. The campsites each have picnic tables and fire rings and you'll need to bring your own firewood. There are individual campsites in the upper part of the campground, and there's a parking area for RVs, with an accessible pit toilet, just below. It's probably a little far from Chicken for people looking for tourist activities but it's a lovely place to stay a few days.

Because I was there as early as I was, the grayling fishing was okay but not spectacular. The fish were skinny (winters up here are very long) and you had to fish pretty deep to find them.

I was there in May, and weather blows through the 40-Mile country very quickly - it can be a bit unpredictable. We had snow at one point. Parts of the Taylor Highway can be a bit sketchy, particularly early and late in the season, but the section between the Alcan and Chicken tends to be in good shape and highly driveable.
