Best Dispersed Camping near Castle Rock, WA

I have camped here twice now, once during a scouting trip in 2016 with my boys and again in September 2024 with just me and my dog :).  I could pull my 17' pop-up "A" frame trailer and back into one of the two spots with no problem.  Due to the narrow road, it may be a bit more snug with bigger rigs (25+ feet long and anything more than 8+ feet wide).  I would scout the road and area before committing; however, there is a turnaround that you could use to maneuver the trailer to drive out.  It's plenty big to accommodate a few trucks/cars and one, maybe two towable trailers.  If you're going tent camping, there are about four flat places for tents.  The area has no trails, so you would not have to worry about people wandering into the campsite. The Ape Caves is a small drive away. The town of Cougar, WA. is about 10 miles away if you need gas or food.  There is a lot of shade, and it is not solar-friendly.  The main road is about 100 feet away, relatively quiet, and very private.  There was a large rock fire pit in the middle. There is no cell phone reception; however, if you drive East for a few miles, you may be able to get 2 bars with Verizon.

Per the state website, "On the southwest side of Mount St. Helens, Forest Road 81 provides an experience away from crowds. On this road, access Kalama Horse Camp, Red Rock Pass, and Forest Road 830, the road to Climber's Bivouac, and the start of the summer climbing route. From the west, the road begins on Forest Road 90, near Cougar, WA, and travels through private timberlands and state lands before entering Mount St. Helens National Volcanic Monument. The road connects with Forest Road 83 on its east side. While mostly paved, be prepared for several miles of gravel(between Forest Road 830 and 8123) and a road that is sometimes very rough."

Great spot because it's so secluded in the forest. There's basically zero traffic on the dirt road near the campsite. A lot of the trees around seem to be new growth. Great view of the stars at night!

There are at least 4 other campsite off this road at different points if you keep driving. Some of them are more or less level and more or less muddy. This one was the best, but there are lots of options. All of them are commonly used because there are ashes from fires. There's a moderate amount of trash at most of them.

Requires a Discovery Pass. I bought a day pass for $12 online since I don't need the annual pass. They tell you to write the date and order number in large print on a piece of paper and put it on your dash. No one came to check my pass though (in January, so it's the off season)

You have to take a dirt road to reach the campsite, but it is pretty well maintained. The only difficulty I encountered were two points where a few inches of road were a bit washed out. They were small enough that I could manage them alright in a 2WD van that had normal clearance. So most cars could probably manage them.

There's a small trail behind this spot that that leads to the creek, which is nice. Other than that, you can hike along the dirt roads, but there aren't any actual hiking trails that I found. I saw a porcupine for the first time while wandering one of the side roads! I didn't drive up to Snag Lake.

There are several spots off the road around these radio tower stations and it is quite secluded. We didn't see any other person the whole time we were there. The spot we chose was the best as it is away from the towers and buildings, plus has a great view overlooking the valley and bay, and you can see the ocean between the peaks in the distance. The road getting here is a bit rough with lots of washboard, steep grades and rocks. But it's fun. No amenities, obviously, but there is a concrete pad from an old structure you can park on. Other sites have solid pack gravel covered by grass.

This dispersed camping is free, huge bonus in my book. While searching for our perfect spot we did come across a few large parties, making us apprehensive that we would experience our ideal peaceful experience, but we were wrong to be. There were dozens of open sites that we had our pick of. A handful of cars drove by throughout the evening and night, but not an outrageous amount. Pretty dang good for very accessible NF camping spots. There are a good deal of trailheads near by, meaning you're never too far from a pit toilet or a bulletin board with information.

We visited in early September and found the weather to be very pleasant. Our view of Mt. St Helen's was obscured by the tall trees that offered our site seclusion and privacy, but we relished the view of the active volcano while driving to and from our site.

This is my first wildcamping/boondocking location, but I loved it. It feels like you're right in the middle of the forest! It's a wide dirt pullout with room for 7-10 cars. And although it's right alongside the road, it's not a super busy road like some highway spots, so it felt pretty secluded and quiet. Very few cars at night.

No signs of any kind indicating "no parking." 1 bar of Verizon LTE.

The dirt was solid -- I wasn't worried at all about getting stuck in the mud (and I'm here in the middle of winter with tons of recent rain). Plenty of room to turn around with ease.

And you're right at a hiking trail that takes you to beautiful falls!! What more could you ask for? -- Don't make the mistake I did. The trail all the way on the left side of the parking lot takes you to the falls. The trails in the middle of the lot are super steep and muddy and don't lead to the falls.

Only downside is it's not perfectly flat. It wasn't too bad though. I just parked with my head pointing uphill when I go to bed, of course.

There is also another option down the road to the east about 500 feet. It's a paved pullout, but it is smaller so it doesn't have as much space to turnaround.

Mt. Saint Helens has become a 4th of July tradition. In 2019, we hiked the Boundary Trail #1 to the Mount Margaret Wilderness overlooking the Saint Helens National Volcanic Monument. We set out to camp at Dome Camp in between Coldwater Peak and Mount Margaret. Permits are required and limited to 4 per night. At the time, they cost $6ea.

Upon our arrival after a ginger 6 hour hike in, we were greeted with expansive views in all directions. There are 2 campsites, one low in the saddle and one up top, with a latrine in between the two. We chose the higher ground one to have an incredible view of Mount St. Helens to the South, The Dome to the East, and Mount Whittier to the NE. The site is nearly perfectly flat with soft sand gravel mix. There wasn't any debris to clear and plenty of room for 2 two person tents. We staked down the tents as it tends to get a bit windy, but guests never got above 10mph. No camp fires, ever!

We arrived around 2pm, just enough time to settle in, set up, eat and then enjoy the landscape's shifting shadows as Sun lowered toward the horizon behind us. The mountains glowed in the summer evening sun as the clouds sunk lower and lower, down into the valleys below us.

Low cloud fronts built strength at the Whittier Ridge and slowly crept over and down into the valley. The fog rolled up over us and The Dome, creating rivers of clouds flowing down into Spirit Lake and the valley. The clouds came in waves drastically changing the environment every 30mins, giving us something new to see everytime.

In the morning, there was a herd of mountain goats along the ridge to the south west looking down over us, playfully dancing along the steep walls. Woodpeckers and coyotes could be heard in the distance truly expanding the environment.
