New Owners: Meet Steve & Stacey

 For several years Steve and Stacey tossed around the idea of owning an RV Park/Campground. Knowing they wanted a lifestyle change, it was time to make their dream come true.   

May 1, 2018, marked the beginning of that dream and a new adventure as they became the new owners of Cougar RV Park & Campground.

Purchasing the RV Park/Campground in Cougar appealed to them as they both enjoy fishing, boating and hiking. Steve also enjoys hunting while Stacey enjoys photography and reading.

Along with Steve and Stacey came two additional new residents, Hercules and Molly, their loving and faithful dogs who enjoy napping and belly scratches.

They have big plans for the RV Park so feel free to stop by and say hi.  And of course, camp!

UPDATE:  We just celebrated our one year "RV Park/Campground" anniversary!!!  Looking back over the last year, we have made many new friends and met some wonderful people from around the world! 

We are excited about the progress and changes we have made and with more changes to come.

We hope to make more new friends this year and to continue providing the best service possible!

Enjoy your day!

Nearby Outdoor Activities

Yale Reservoir

The closest access to Yale Reservoir (boat ramp and day use area) is less than one mile from the campground.  The main attraction at this reservoir is Kokanee. Although there are four boat ramps on the reservoir, the water level fluctuates making access by boat difficult at times. 

This reservoir is located on the North Fork Lewis River.  Shallow fishing for kokanee is best in the spring and fall; in the summer months deep fishing is the best method. Coastal Cutthroat Trout can be caught near the mouth of Siouxon Creek.

There are some Bull Trout in the reservoir. All Bull Trout and Dolly Varden must be released. Fees are required to launch on weekends. All ramps may be out of the water when the lake level is lowered. Call (800) 547-1501 for updated reservoir levels.

Swift Reservoir

Swift Reservoir is located approximately 12 miles northeast of Cougar, on the south side of Forest Road 90. During April and May fish tend to congregate near the dam and around streams entering the reservoir. By June, trout should be dispersed throughout the reservoir. Landlocked salmon rules apply with a 15" maximum size on salmon caught.

Selective gear rules are in effect in the upper portion of the reservoir; check the regulation pamphlet for boundaries. A public boat launch at Swift Forest Camp, managed by PacifiCorp, has two concrete ramps. There is a fee to launch on weekends.

Merwin Lake

The reservoir fluctuates depending on the amount of run-off making boat access difficult at times. 

Kokanee are the main target, however, Tiger Muskie planted in 1995 are also popular with anglers.   

Angling is best in early spring, with Kokanee averaging 12"inches. 

All Bull Trout and Dolly Varden must be released.

PacifiCorp operates boat launches at Speelyai Bay (14 miles away) and Cresap Bay (19 miles away).  There is a fee to launch on weekends.Call (800) 547-1501 for updated reservoir levels. 

There is very limited shore access

Merrill Lake

This fly-fishing, catch-and-release-only lake is located north of Cougar (5 miles) near Mount St. Helens. It is open to fishing year-round, but action is usually slow and often inaccessible during the winter months due to snow. The lake was formed when lava flows from Mt. St. Helens blocked the stream valley. Merrill contains Coastal Cutthroat, Brown Trout to several pounds and some Rainbow Trout and Eastern Brook Trout. 

This lake is stocked annually with rainbow, browns, and brooks. 

Ape Caves

The third longest lava tube in North America, known as the Ape Caves, formed more than 2,000 years ago, but it wasn’t discovered until 1947 by a logger named Lawrence Johnson. There are two entrances: Lower Cave Section (shorter and easier route) and the Upper Cave (longer and more difficult route).  For more information:

Trail of Two Forests

This trail loops through two forests that stand side by side, but are separated in age by 2000 years. One forest is old-growth Douglas-fir and western red-cedar and the other is a young forest that was originally engulfed by lava flows from an eruption of Mount St. Helens over two millennia ago. The boardwalk trail loops through the two forests, and is kid- and wheelchair-friendly. For more information:

Camping Etiquette


Whether you’re an experienced camper or planning your first outing, be sure you mind your manners at the campground! Camping etiquette is, for the most park, common courtesy. Here are a few suggestions on being a courteous camper:

· Respect other's rights. Don't walk across another camper's site - walk around it.

· Obey the campgrounds quiet hours. Voices, radios and other noises carry further than you might think on a quiet summer night.

· Pack out what you pack in. A good rule is to leave your campsite cleaner than you found it. Recycle when possible.

· If you own a pet, keep it contained and clean up after it. Don't expect to tie your dog to a tree and leave him unattended. He will likely bark at strangers, dig holes and annoy your fellow campers.

· Don't cut living trees for firewood. Know the campground's rule on finding your own wood or buying it.

· Campground facilities exist for the benefit of all campers. Help keep them clean!

Know and respect the campground's rules, even if you don't understand them all. Feel free to ask for explanation of any of them. The rules have been established to protect and respect the rights of campers, the campground and the environment.

We are a pet friendly RV Park and to continue allowing pets we enforce a strict pet policy. Please always have your pet on a leash (no more than 8 feet) and pick up after them (even in the National Forest). We have pet waste bags available by the office door.

If your dog disturbs or threatens another guest or employee of the RV Park, the dog will be asked to leave.

We do allow pets inside our the bunk cabins only. Under no circumstances may any pet be left in the Cabin unattended. We ask that no more than 2 pets at any one time be allowed inside the Cabins.
