Description

State Park

Far in the Northwestern corner of the United States lies a world of magic, splendor, and mystical beauty. Perched atop the historical Mount St. Helens, Seaquest State Park is the home-base for thousands of volcanic visitors year round. Most notable for its proximity to the Mount St. Helens Visitors Center, this park is the home base for hikers, explorers, tourists, and adventures alike. It’s not just the volcanic aftermath that makes this area so special. Even before the eruption, Gifford-Pinchot National Forest has always been known for its dense foliage, as well as its beautiful lakes, tributaries, and waterfalls.

When it comes to nearby attractions, the area is packed with them. Miles and miles of trails fork and wind throughout the park. Beyond the confines of the park’s boundaries are numerous additional trailheads, all offering something unique to those seeking it. Perhaps the most popular trail nearby is the Monitor Ridge trail. This 10 miles round trip excursion will have you climbing 2,000 vertical ft. through grassy meadows and winding forest paths. The last 1,000 feet are especially difficult due to the volcanic debris and soot that cakes your clothes. However when you finally reach the domed summit, you’ll be pleased with your efforts. Massive and expansive, the St. Helens dome is unlike any other scenic viewpoint in the US. Nowhere else can you see the true force and impact of Mother Nature’s wrath.

Nearby, the Mount St. Helens Ape Caves give visitors a chance to traverse through the labyrinth of volcanic caves left behind by magma runs during the the eruption. Today, the caves are a popular attraction for families and explorers. There’s two separate options, one which is well-lit and suited for families. The other option will send you through a pitch black adventure trekking the depths of the craggy, drippy tunnels. If planning to visit, be sure to bring a strong flashlight or kerosene lantern, as you’ll be unable to enter otherwise.

Camping in Seaquest State Park is relatively painless thanks to the 52 standard campsites, 18 partial-hookup sites, and 15 full-service sites. RVers, tent campers, van travelers, and anyone else with a form of shelter should have no issues finding somewhere to stay here. Aside from standard camping accommodations, there are also full-service Yurts available for rental, complete with heaters to stay warm if you’re visiting in the chilly months.

Great Spot for Exploring Mount Saint Helens

I gave this park a high rating primarily because of its location. It is a great place to launch your Mount Saint Helens exploration, with a Washington State Visitor Center you can walk to from the campground. We had hookups but our site was very close to the site next to us and we had no privacy there. If you don’t need hookups, I would recommend the loop that has 32 - 54. These were much more private and actually had better Wi-Fi than our location. Bathrooms are convenient and have free showers. There was better hot water at the bathroom on the loop with sites 32 - 54.

Solid

Seaquest has something for everyone. My campsite was not close to the road , but I stayed when Johnston Ridge was closed, so maybe road noise would be a factor at other times.

Some pluses here include: some private sites, lots of trees, bathroom / showers, playground, open areas, close to other points of interest. And for those who can’t live without it: WiFi.

Although bathrooms were clean, I believe they could use an upgrade. Showers in particular.

Secluded campsites, nice facilities

We went over Labor Day weekend with a small group and had two adjacent campsites. The sites were large and well graded. They were also well separated from each other with lots of vegetation dividing them. Bathrooms seemed to have been recently upgraded and were some of the nicer state park bathrooms we’ve come across. Kids enjoyed the junior ranger program and the Mt St Helens visitor center across the road has great exhibits on the eruption. About a 40 minute drive to Coldwater lake where you can access a number of trails closer to the volcano.

But the wireless is really only in the day use area. I'd love it if it works throughout the campground but no. The spots are nice though and there is a lot of shade. Odd to be so near a big lake and really, it doesn't seem to have any access to it. Loads of trails though which is nice.

Nice Little Getaway

It was a great place to escape from everything for a night. We stayed at site 35 in a tent, and it was perfect. A little dip down and isolated enough perfectly for my wife and I. A nice fire ring, picnic table, and plenty of space for our Rav4. It was really busy but our area was almost completely empty so we had a blast. Awesome staff and clean bathrooms.

Relaxing weekend get-a-way!

This was what I would call perfect winter camping- no rain but chilly. It was like being deep in the forest but with the convenience of a full-hook ups. (Water is shut off in the winter but you can fill your tank at the park. The “tt” sites are just like regular rv park types- field of grass w/ picnic tables. The straight #s are the sites in the forest.

Shady noisey

We spent 3 nights here July 19-22. The facilities were adequate and clean. 3 minutes per token for the showers. The sites are pretty well spaced which was nice. It is very shaded which is good if it's hot but not so good if you are counting on solar.

The campground is located directly across hwy 504 from the Mt Saint Helen's visitor center. There is even a walking tunnel under the hwy from the campground.

The general discription here in thedyrt says there is wifi. There is no wifi in the park. We had extended Verizon service. So we could text usually and even in a few spots could make a call but no data access.

The nearest data connection we found was back towards Castle Rock / I-5 3 or 4 miles. The downtown area of Castle Rock is a pretty nice place with a couple pubs and a few restaraunts and a small grocery store. 

I would recommend avoiding the loop of sites 55-76. They are the closest loop to the hwy and the hwy noise is very noticable.

*about 40 miles from campsite to main visitor center for Mt St Helens *If you want to see Spirit Lake etc, you will want to camp closer to the mountain. From Sequest State Park, it was a 10 hour day to do the loop in order to see the east side, with only one short hike thrown in. *as of this date, all visitor centers are closed due to covid. But for some reason the forest service and park service feel it's ok/safe to keep the gift shops open... masks are required. *the signage at the overlooks is very good however, so we felt we weren't left short of information with the visitor centers closed.

Regular campsites and yurts - YES; RV spots - NO!!!

I love Seaquest for their beautiful campsites and the proximity to a wonderful forest to bathe in. But don't go for the RV sites, which are laid out in a parking lot setting with no real distance from neighbors and not surrounded by trees. Unless that's your jam. It was definitely not ours, tent camping alongside some friends with a trailer who liked nothing more than to hang out at said trailer, and walk through the campground to look at other.. trailers. I don't think they even stepped foot in the 7+ miles of forest trails which is a few steps away. If you can step away from the hookups and get a real campsite off the RV pad, it is a stunning experience. Each site is surrounded by trees, creating privacy and serenity.  Another great option is the yurts. We stayed in Yurt 2 (the only pet friendly yurt) and loved it. 

For those with RV's, trailers, campers - look into the regular sites because I think some of them even have hookups and can accommodate most sizes. Just steer clear of RV sites T1-T16.

Great wooded spot!

Had a great time here, the sites were spaced out and private. It was a bit noisy being by the road, but there are spots farther away that would be a lot quieter. Went paddle boarding nearby in a great lake and took the time to drive up to Mt. St. Helens.

Nice park primitive sites $20 pw $30 full hookups $35. Full hookup sites are more like a RV park than a campground

Not far from freeway and Mt St Helens visitors center. The Johnson Ridge observation point is about another 35 miles away. Both were closed when we were there on 3/26/21. There are sites from tent only to full hookup. The ones towards the front are close together with power and water. Thick trees makes it pretty shady. The biggest sites are in the back loop. They were closed not sure if it was the season or the fact that many had extensive wind damage.

Easy Access to Mount St Helens

Loved the yurt village, which is in its own area on the other side of the campground from the regular sites. Yurts and restrooms were clean. Beware the mosquitos! We always get eaten alive when we stay at Seaquest. Easy access to the Mount St Helens area. Johnston Ridge Observatory was closed when we were there but we were still able to see some amazing views and get some nice hikes in nearby.

nice, but noisy

I didn't have reservations.  Securing a spot was easy enough using the phone at the ranger station (it was after the rangers had gone home for the day).  Most of the sites had a level spot(s) for a tent.  There was a picnic table and I fire ring.  There was a. very clean bathroom with flush toilet and shower (shower operated on tokens; I didn't use it).  Near to the restrooms was a high flow potable water spigot (which I used to top off my water supply---tasted great). There were lots of families camping (August) and the expected noise that comes with kids playing.  The unexpected noise came from Hwy 504.  I was in the lower campground (closest to the highway) and the noise was omnipresent until about 1030pm and started up again around 530am.  If I were to return to Seaquest, I would make sure that I got a site further away from the highway.

Beautiful, clean, quiet.

My family loves this campground. It is very peaceful, very clean, friendly people. Paved roads surround several loops. Tent camping and trailer camping is plentiful. Majority of sites are private. There is a playground for kids and many trails surrounding the park. We live within 20 min and this is our choice for camping. The campground is located across the highway from one of 3 Mt St Helens visitor center with a tunnel that goes under the Hwy to get you safely from the campground to visitor center. If you are going to see the mountain this park is a great place to stay at and then head up to the mountain in the morning and come back to camp another night. There is a very nice ADA accessible trail around the wetlands that are on Silver Lake. If you enjoy star gazing there is a large open field that you can lay in at night and make a wish on numerous shooting stars you may see. Absolutely a great place to stay for a night or a week.

This is a great family campground.

We (2-adults) spent two nights: Sun & Mon. The campground is huge but our site felt fairly private even though there were lots of campers around. Good, clean services (toilet, water, trash bins); it's very well maintained. 

We explored the area near Mt. St. Helens during the day; there are plenty of lakes and hikes around. 

For what it is it's great. If you are looking for more remote and fewer campers, it may not be your first choice but for an easy getaway between Portland and Seattle, we enjoyed our time.

Nice little State Park

Keeping in mind that we went during a rainy season (fall), this wasn’t a terrible place.

On the way to Mt St Helens, it is a nice base camp for exploring the area a bit, though we didn’t do much of that. I would certainly expect that we would the next trip here.

The good: Fairly Quiet. And that’s staying in the full service trailer area, which is more of a parking lot than a camp ground.

The bad: the loops are not clear on the direction of travel in this spot, and we had a fellow drag his trailer across the front bumper of my Jeep soon after I was backed in and settling the details of my placement. I’m not certain if he was traveling the correct way, but he didn’t have enough room to accomplish his mission and he definitely was traveling the opposite direction that I used to correctly back my trailer in.

Now he has a hole in his trailer which didn’t seem bother him as much as the twisted bracket on my bumper bothered me.

My brother and his wife tent camped on our site, and ended up swimming in rainwater overnight (the slope of the land didn’t help, but they have since also purchased an RV after this final tent experience).

This section also had no tree cover and was widely exposed to the elements.

I would definitely try this campground out again, but for now it was slightly disappointing.

Nice place to camp

We were looking for a place between Portland and Seattle for one last night of camping. We were able to get site 12 the day we arrived at Seaquest without an advance reservation. It’s near a water spigot and not too far from the bathhouse.

One bathhouse included in my pictures was part of another loop that was on the walking path to the Mount Saint Helens Visitor Center, located across the street. A short tunnel goes under the road for safe access to the visitor center.

Seaquest State Park has a small playground and picnic area. There’s not much else to the park. It’s proximity to Mount Saint Helens probably makes it popular. The facilities were clean and the campground was quiet. Nice place for a quiet, relaxing camping experience.

Such a well maintained park. The sites were big and while we had neighbors on all sides there was enough distance and tree/fern cover to feel private. We stayed at site 41, which had a trailhead right beside it offering a leisurely walk to explore the surrounding woods. An easy walk to a visitor's center with a decent exploration of the Mt Saint Helens eruption. The center is also surrounded by a wetlands nature walk that has some great birdwatching.

First time camping and doing it across the states starting in Tacoma WA and ending in Savannah GA. First stop was here and it seems like it’s setting the bar high. Super easy to find and claim a spot. Campsites were clear and a decent size with picnic table and a fire pit with a grill. The bathrooms have hot water and were clean. I was very impressed.
